404 Records of the Indian Museum. [ VOL, XID; 
of the mid-dorsal line, is large and procurved. The eye is exceed- 
ingly long, reaching beyond the end of the antennular peduncle ; 
it is composed of two distinct segments, the proximal and more 
slender of the two bearing a conspicuous dorsal spine. The anten- 
nules and antennae are normally developed, except that the 
lateral process on the basal segment of the former is rudimentary. 
The third maxillipedes and all the peraeopods except the last bear 
very long exopods. The chelae of the first and second pairs are 
more rudimentary. The full series of gills appears to be present 
but there is no trace of epipods. The pleopods and uropods are 
well formed and the apex of the telson resembles that of the post- 
larval specimens, but possesses a pair of setae near the middle. 
So far as I am able to discover the larva differs from that of 
all other Carids hitherto described in the possession of a large spine 
on the eyestalk.

Borradaile’s description of this species runs as follows :— 
‘“ Rostrum *", straight but upcurved at end, outreaching anten- 
uular stalk. Third maxilliped as stout as first leg, in which hand 
and arm are subequal, wrist a little shorter. Second wrist has 
20-22 joints, the last the longest. Maldive Is.’’ 
The Andaman specimens agree well with this description as_ | 
far as it goes. The rostrum reaches beyond the end of the anten- | 
nular peduncle and is almost or quite as long as the carapace ; it 
is furnished with 9 or 10 teeth above and with 5,6 or 7 below. The 
posterior tooth of the dorsal series is situated a little in front of 
the middle of the carapace and is separated by a marked interval 
from the rest; the latter are rather crowded posteriorly but more 
distantly spaced on the rostrai blade; two of them (that is to say 
three teeth in all) are situated on the carapace behind the orbital 
notch. The teeth on the lower margin are as large as those on the 
upper. Theieis alarge antennal spine on the carapace and another, 
which is smaller, at the pterygostomian angle. 
The lateral process of the basal segment of the antennular 
peduncle is short, not reaching to half the length of the segment; 
its outer margin is strongly convex. ‘The outer antennular flagel- 
lum is thickened at the base, but is devoid of the accessory ramus 
found in species of Lysmata. The antennal scale is narrow, scarcely 
broader behind than in front, and four times as long as wide. 
The outer margin is conspicuously concave and terminates in a 
sharp spine that reaches beyond the distal end of the lamella. 
The mouth-parts closely resemble those of H. vittata. All three 
maxillipedes bear epipods; the exopod of the last pair reaches 
beyond the middle of the antepenultimate segment.
