callosity which is u n ite d to th e labrum above a n d being
slig h tly expanded almost conceals th e umbilical fissure.
Length, 7 lines, bre ad th 34, a smaller specimen is 4 f
lines long and 2 | broad.
The spiral lirations are ra th e r more p rominent th a n the
lo n gitudina l ribs, and th e three on th e superior h a lf of the
whorls are finer th a n those on th e lower portion. The
])oints of intersection are fa in tly nodulous.
The figure representing th is species is n o t characteristic,
for i t is ta k e n from a young example, and th e form of the
mouth is very different from th a t of th e ad u lt shell.

Mr. A. Adams describes th e colour of this species which
appears to have been overlooked by Von Martens in his
List of New Zealand Shells as. “ v irescenti.” All three
specimens in th e Cumingian collection are yellowish
(luteus). H e writes “ labro in tu s sidcato,” which refers to
th e th re e or four shallow sulcations placed fa r w ith in the
aperture. The dimensions of this species are as follows :
greatest he ig h t 16 m ill; diam. 19.

Placiphora terminalis, Cgrr. MS. (in Coll. Cmning.)
Shell elongately ovate, ra th e r elevated, roundly angled
along th e top of the valves, black or bluish-black, with a
white wedge-shaped stripe with a black one w ith in it
down th e centre of the valves, forming a continuous
white stripe divided by the black one along the centre ol'
the shell, in some specimens with a few short white da.shes
diverging from th e rad ia tin g ridges. The intermediate
valves mucronated, bisected on each side by one raised
radiating rib, the posterior margins sinuated and thickened
by coarse concentric laraelUe : th e entire surface is covered
with m inute striate-wrinkling, those near the ridge being
coarser th an th e re st and radiating from it like the webs
from the shaft of a feather. The posterior terminal valve
has th e m uero quite tenniual. The anterior valve radiately
eight-ribbed (at times one or two additional minor ones are
present) with diverging oblique striations on each side of
them. In te rio r of valves g re en ish -b lu e ; valve lobes
whitish, th e sinus between them deep ; th e h airs or bristles
on the mantle-margin are short, few and horny, those
arising from the nine pores being th ick e r th a n the rest.
Largest specimen (in a contracted state) 42 mill, lo n g ;
width ol' valves, 20.
An average specimen. Length, 25 m i l l ; width, 11.
Hab. New Zealand {Col Bolton an d Capt. Stokes).
“ Terminalis ” appears to be b u t a man u sc rip t name
attached to some specimens in th e Cumingian collection.
As I understand th a t Dr. P. 1’. Carpenter is engaged on a
work on Chitonidce I retain the characteristic name he
imposes.
The central white stripe w ith th e black one w ith in it
appears to be very constant.

This species m ust n o t be confounded w ith T. lata,
Deshayes, which is distinguished a t once by the sinus in
th e pallial line being ra th e r shallow in comparison with
th a t in vexitricosa, which is considerably deeper, and tlie,
la tte r shell is more iimequilateral, and has two obsolete
keels (in th e figure only one is shown) radiating from the
umbones to th e margin down the anterior end of the
valves, whereas iii lata there is but a single obsolete angulation.
