 extends obliquely  above  the  outer margin of  the  branchial  opercula;  along the middle’ of  the  
 upper part there is  a row of small, white  spots, the  one  immediately above the  spinners, which  
 terminates  the  series,  being  the  most  conspicuous;  the  spinners  are  cylindrical  and  rather  
 prominent.  Some  slight modifications  of form  and  size may be perceived,  occasionally,  in  the  
 white lines  and  spots,  so remarkable  on this  species. 
 The male  is  smaller than  the  female,  but  it  resembles  her  in  colour.  The  cubital  and  
 radial  joints  of  its  palpi  are  short,  the  latter  projecting  a small, pointed  apophysis  from  its  
 extremity,  on the outer side;  the digital joint is  of  an oblong-oval form,  somewhat pointed  at  
 the  end;  it  is  convex  and  hairy  externally,  concave  within,  comprising  the  palpal  organs,  
 which  are  highly  developed, with  a  small, prominent,  curved  spine  underneath,  and are of a  
 red-brown colour. 
 In warm  sunny weather in  spring and  summer this  small  but brilliant spider may be seen  
 running  on  the  ground  in  the woods  of  Denbighshire, Caernarvonshire,  and  Berwickshire.  
 Like many other species of Araneidea, it is  partial to moisture, and drinks water freely.  A pair  
 confined  in  a  phial  having  become  feeble  and  greatly  emaciated,  they were  supplied with  a  
 few drops  of water,  which  they  drank with  avidity,  and speedily  resumed their strength and  
 former plump  appearance.  In  the month  of May,  1833,  females,  in  a  state  of captivity,  constructed  
 cocoons  of  a  hemispherical form, measuring  about one  sixth  of  an. inch in diameter,  
 in  each  of  which  they  deposited  nine  or  ten  spherical  eggs  of  a  pale-yellow  colour,  not  
 agglutinated  together.  The cocoons were  composed  of.  delicately white  silk,  of  a  very  fine  
 but compact texture;  and  connected with  the  upper  part  of  each  was  a  tube  of  the  same  
 material, usually occupied by  the female.

 Length  of  the  male, |th  of an  inch;  length  of  the  cephalo-thorax, ^th,  breadth,  5'?th;  
 breadth  of  the  abdomen, ^th;  length  of  a  posterior  leg,  «th;  length  of  a  leg  of  the  third  
 pair, |th. 
 The legs are long,  slender, provided  with  hairs  and  sessile  spines,  and  of  a  yellowish-  
 brown  colour,  with  the  exception  of  the  femora  of  the  first and  second  pairs, which have  a  
 dark-brown  hue,  those  of  the  second  pair  being  the  paler;  the  fourth pair  is  rather longer  
 than the first, which  surpasses  the  second,  and the third  pair  is  the  shortest;  each  tarsus is  
 terminated by  two plain,  curved  claws, below which there  is  a  small  scopula.  The  palpi  are  
 robust;  the  humeral  and  cubitaljoints  are  somewhat darker  coloured than the  legs,  and  the  
 radial  and digital  joints  have  a  dark-brown  hue ;  the humeral joint has  a gibbosity  near its  
 extremity,  on  the under side, which is  provided with  short hairs;  and the  radial joint projects 
 CLUBIONA. m 
 forwards, from  its  outer side,  a  very large, curved  apophysis, whose yellowish-brown  extremity  
 is  slightly bifid ;  the  digital joint  is  of  an  elongated  oval  form,  convex and hairy externally,  
 concave within,  comprising  the  palpal  organs;  these organs  are  highly developed,  very  protuberant  
 at  the  base, which  is  convex  and  glossy,  and have  a  small,  prominent  process  at  
 their extremity ;  they  are  of a  dark-brown colour,  faintly tinged with red.  The  eyes  are  dis-  
 . posed  on  the  anterior  part  of  the  cephalo-thorax  in  two  short,  transverse,  slightly  curved,  
 concentric  rows, whose  convexity is  directed backwards,  the  intermediate  ones  of the anterior  
 row being rather the  smallest and darkest of the  eight.  The  cephalo-thorax is  ovalj'fpnvex,  
 glossy, with.slight furrows  on  the  sides -converging towards a  narrow indentation  in the medial  
 line ;  it ,is; sparingly  clothed  with hoary hairs,  some  of which  are .disposed  in  three faint rows  
 on  each  side, along the furrows ;  the  fa lc f| are  conical,  vertical, and  armed with a  few minute  
 teeth  on  the  inner  surface ;  the maxillæ are powerful,  enlarged where the  palpi  are  inserted,  
 greatly, dilated  at  the base,  rounded  at  the  extremity,  and  inclined towards  the lip,  which is  
 Jonger.thanbroad.and  rounded at the  apex;  the  sternum is heart-shaped.  These parts  are  of  
 a brown  colour ;  the margins  of  the  cephalo-thorax,  and  the  base  of  the lip  being much the  
 darkest.  The  abdomen  is  oviform,  glossy,  thinly'Sejothed  with  short  hairs,  convex  above,  
 ■projecting  a  little, over  the  base  of  the  cephalo-thorax,  and  is  of  a  dark-brown  colour,  the  
 -under part being the palest ;  there is  a  spot on each side of the  anterior extremity,  a fine line  
 extending thence-along  the. middle  of .the upper part,  nearly half of its  length,  and  an  oblique,  
 transverse, curved line, whose-extremities  pass  along  the  sides  to  the under part,  and whose  
 middle portion,  abruptly curved  forwards,  is  bisected  by  the  point  of  the  fine  medial  line;  
 these marks  are  somewhat obscure,  of a  deep,  yellowish-browu hue,  and are sparingly covered  
 with hoary hairs ;  a few white hairs form  a  minute  spot immediately above  the  spinners,  and  
 the  colour of the branchial  opercula is  brown. 
 Two  adult  males  of  Drassus propinquus,  which  is  closely  allied  to Drassus nitens, were  
 captured  in  the  spring  of  1853 ;  one  running on a public road  near Llanrwst,  and the  other  
 in  a  window  of  the  sitting-room  at  Oakland.  In the  summer  of  the  same year Mr.  R. H.  
 Meade  took  an  adult male  of this  species in Norfolk.

 not differ greatly in size. 
 Maxilla long,  straight,  and  enlarged  at the  extremity. 
 L ip  long and  somewhat oval,  or truncated 'at the  extremity,  and nearly quadrangular.
