304 Records of the Indian Museum. [ VoL. XII, 
The mandible resembles that found in the genus Thor; the 
incisor-process is well developed and is furnished with about seven 
teeth at the apex. The palp is entirely absent and the molar pro- 
cess is cleft and furnished with slender spines, many of which are 
serrate. 
The second maxilla is normally developed; the distal endite 
of the endopod is divided into two parts of equal breadth. The 
first and second maxillipedes possess epipods, that of the former 
being emarginate distally, while that of the latter is deeply bilobed. 
The ultimate segment of the endopod of the second maxillipede is 
placed terminally at the end of that which precedes it and is not 
applied as a strip along the outer margin of the latter as in the 
great majority of the Caridea. The third maxillipede {(text-fig. 2d) 
does not possess an epipod; the exopod is small but foliaceous, 
reaching about to the middle of the antepenultimate segment. 
The ultimate segment (text-fig. 2e) is less than twice the length 
of the penultimate and is not three times as long as broad; in 
addition to numerous hairs it bears a series of nine or ten sharp 
spinules in its distal half. 
The first peraeopods (text-fig. 2/) are stout, but very short ; 
the ischium and merus and carpus are sub-equal, a little shorter 
than the chela. The segments bear long setae but are otherwise 
unarmed. ‘The chela (text-fig. 2g) is rather more than twice as 
long as broad and the fingers are distinctly longer than the palm. 
On the internal surface of the chela the fingers are deeply hollowed 
or spooned near the cutting margin, while externally each forms 
a thin blade with a saw-like edge, the two meeting throughout 
their length when the claw is closed. At the extreme tip each 
finger is provided with three large teeth. 
The second peraeopods (text-fig. 24) are much longer, reach- 
ing nearly to the tip of the antennal scale. The carpus is almost 
as long as the ischium and merus combined and consists of two 
segments, the second a little shorter than the first and about twice 
as long as broad. The chela is almost two-thirds the length of the 
carpus and nearly two and a half times as long as wide. the fingers 
being about one-third shorter than the palm. When the claw is 
closed the fingers meet only at the tips where they cross each other. 
The last three pairs of peraeopods (text-fig. 27) are similar and 
show no sexual differences. The carpus is scarcely shorter than 
the merus and is a trifle longer than the propodus. The propodus 
is armed beneath with five or six spines, two pairs towards the 
distal end and one or two others, which are smaller, near the mid- 
dle. When the dactylus is folded inwards it lies between the two 
spines constituting the distal pair and thus forms a poorly de- 
veloped grasping organ. The dactylus (text-fig. 27) is short, spines 
included about two-fifths the length of the propodus: on its in- 
ferior edge it bears a series of seven or eight spinules which in- 
crease in size distally, the two terminal ones being large spines. 
All the legs bear very long plumose setae, especially conspicuous 
on the ischium, merus and carpus.
