Careinological Fauna of India. 167 
female they are hardly stouter than the legs; but in the male they 
are distinctly stouter, especially as regards the palm, which is club- 
shaped: the palm is much longer than the fingers. 
The first three pairs of legs increase in length, gradually but 
slightly, from before backwards, the 3rd pair being between 4 and 43 
times the length of the carapace: the dactyli are long and curved. 
The fourth pair of legs are a little longer than the male chelipeds: 
their last two joints are short, and the dactylus folds down, like a knife- 
blade, on a*double row of spines along the posterior border of the 
propodite. 
In both sexes the last abdominal tergum is shaped like a spear- 
head, and the 2nd 3rd 4th and 6th terga have an acute tubercle in the 
middle line. 
The carapace of an egg-laden female is 8 millim. long, the same 
length as that of an apparently adult male. 
Colours in spirit yellow, the fingers and eyes dark brown. 
In the Indian Museum are two males and a female from the Anda- 
man Sea, 53 fathoms (not the same station as that where Latreillia was 
dredged). 
Distribution : off the Andamans and off the Philippines.

Carapace elongate-piriform, not covering the basal joints of the 
legs, its anterior part prolonged to form a subcylindrical “neck” at the 
end of which are the spiniform rostrum, lying deflexed between two 
long slender divergent “ supra-ocular” spines, the eyes, the antennules, 
and the antennz. The regions are fairly well indicated, and there is 
no linea anomurica. 
Hyes much as in Homola, large and borne free at the end of very 
long and slender basal stalks. Antenne short, of filiform slenderness, 
freely movable from their base. 
Kpistome of great length fore and aft, corresponding with the 
“neck” of the carapace. Buccal cavern well demarcated from the 
epistome, the efferent branchial channels well defined. External 
maxillipeds not completely closing the buccal orifice: they have a 
pediform cast, the ischium and merus being rather narrow and the 
flagellum coarse.
