15. Galathea spinosirostris, Dana ?
To this species are rather doubtfully referred female specimens
collected at Alarie-Louise Island, 17 fms. (No. 186) ; He des Neufs,
15 fms. (No. 187) ; and Providence Island, 19 fms. (No. 187).
These specimens differ from Stimpson’s description of Galathea
lahidolepta *, based on specimens from tbe Cape of Good Hope, and
from a dried example (probably male) in the Aluseum collection
from Simon’s Bay {J. Macgillim'ay, H.Al.S. ‘ Battlesnake ’), only in
having the strigæ of the carapace (in the adult) very scantily
pubescent, tbe lateral margins of tbe carapace armed witb nine
spinules, aud tho palms of the chelipedes very slender and scarcely
scabrous above, but they are spinulose and setose nearly as in
Stimpson’s description.
Dana’s G. spinosirostris is but briefly described, and he does not
state bow many spinules there are on tbe lateral margins of the
carapace in his types, which were from the Sandwich Islands ; the
description and figures, however, agree fairly woll witb our specimens.
Dr. Bichters refers to tbis species specimens from the Foiiqiiets.
Two small specimens from Darros Island, 22 fms. (No. 233), mucb
more nearly resemble G. lahidolepta in the more distinctly strigose
and pubescent carapace, whose lateral margins are armed wdtb seven
or eight spinules (including the infra-antennal spine). In one of
these specimens (a male) the palm of tbe chelipede is more broadly
dilated and tbe fingers relatively shorter than in tbe specimen from
Simon’s Bay referred to above.
16. Munida edwardsii. (P late LI. fig. A.)
Tbe carapace, as usual in the genus, is transversely strigose ; the
strigæ ciliated ; tbe lateral spines of tbe rostrum are rather more
than half as long as the median spine ; outside of tbe lateral rostral
spines there is a small supraocular spine. The front of the gastric
region is armed with a transverse series of about eight spinules ; on
tbe sides of tbe carapace, near to tbe lateral margins, are two
spinules, situated one in front of and one behind tbe cervical suture ;
tbe antero-lateral angles of tbe carapace are bispinulose, and posterior
to these, on the lateral margins, are six spines ; the postabdomen is
without spinules on tbe dorsal surface, and the lateral margins of
the second to sixth segments are rounded. The corneæ of the eyes
are considerably dilated ; tbe terminal peduncular joints of tbe
antennules are armed witb four spinules, of wbicb one is very long ;
tbe peduncular joints of the antennæ (except tbe last) are each
armed witb a spinule (tbe flagella, botb of antennules and antennæ,
are wanting in tbe single specimen examined). Tbe chelipedes (in
the male) are ratber robust, tbe merus enlarging distally and armed
witb superficial and marginal spinules at and toward its distal extremity
; carpus spinulose above and on tbe margins ; band somesiij'

what dilated, and vertically flattened and compressed; tbe margins,
both of palm and fingers, spinulose, but tbe surface smooth, without
spines. But one ambulatory leg remains attached to the body (on
tbe left sid e ); this is ratber small and slender, and has the upper
margin of the merus, carpus, and penultimate joints spinulose, the
dactyl obscurely denticulated below. Colour iight brownish pink
or yellowish. Length of the body to end of rostrum nearly 6 lines
( 1 2millim.); of a chelipede about 6 | lines (14 millim.).
Tbe single specimen (which is, I think, a male) was obtained at
He des Neufs, 15 fms. (No. 187), witb Galathea spinosirostris.
^ Tbe spinulation of tbe carapace, with the form of the chelipedes,
distinguishes it from all the species with which I am acquainted.
The presence of supraocular spines will at once separate it from
the Oriental forms Alunida gregaria (Fabr.) = ilf. suhrugosa, Dana,
AI. japónica, Stimpson, and also from AL. spinulifera, described at
p. 279 of tbis Beport.
AIACBUBA,
1. Alpbeus obesomanus, Dana.
A specimen was obtained at tbe Seychelles, 4 -12 fms. (No, 194).
I t has been already noticed at p. 287 of tbis Beport.
2. Alpheus edwardsii (Audouin).
A specimen, in which tbe smaller chelipede is wanting, was obtained
at tbe Seychelles, 4 -1 2 fms. (No. 194). I bave already
referred to tbe distribution, sexual characteristics, and variability of
tbis species a t p. 284 of this Beport.
3. Alpbeus lævis, Bandall.
Of tbis widely distributed species specimens were collected at tbe
Seychelles, 4 -12 fms. (No. 194); African or Eagle Island, 10 fms.
(No. 184); and Etoile Island, 13 fms. (No. 191) : most of these are
ova-bearing females.
Specimens are in the Britisb-AIusenm collection from the Bed Sea,
Gulf of Suez (R. MacAndreiv); Gulf of Akaba (Major Burton) ;
E l Tor (Major MacDonald); Daedalus Shoal (Lt.-Col. Playfair) ;
also Bed-Sea specimens received from the Godeffroy Alusenm, and
wrongly designated A . tricuspidatus, Heller; also from Bodriguez
(H. H. Slater); Cejdon, Galle (Dr. W. Ondaatje); Samoa Islands
(Rev. S. J. Whitmee); and Fiji Islands, Alatuka (H.Al.S. ‘ IleralcV).
There is in tbe collection a specimen of Alpheus from African or
Eagle Island, 10 fms. (No. 184), wbicb for tbe present I refrain
from designating by a distinct specific name. I t is evidently very
nearly allied to Alpheus collumianus, Stimpson*, from tbe Bonin
