The front projects beyond the margin of the buccal cavern and 

 ends in three teeth of nearly equal size, but it is not prolonged back- 

 wards as a ridge between the hepatic regions. The external orbital 

 angles are not acute. 



The hepatic regions have no convexity distinct from the general 

 convexity of the carapace. 



In the male the third thoracic sternal segment is produced, on 

 either side of the abdomen, to form a laminar tooth which projects 

 forwards, across the secoud segment, well on to the first. And the 

 margins of the fossa in which the tip of the abdomen is lodged are 

 finely beaded. 



The chelipeds in the adult male are twice the length of the cara- 

 pace, and are exceptionally massive — the arm being between a half 

 and a third as broad as long : the arm has its inner border and proxim- 

 al half of upper surface beaded, its inner surface completely covered 

 with vesicular granules, and its under surface smooth : the wrist and 

 hand are quite smooth, the hand of the adult male being as broad as 

 long : the fingers are stout, as long as the hand, and meet only at tip : 

 the dactylus in the male has one of its teeth — situated near the 

 middle — -of very conspicuous size ; the fingers in the female are without 

 teeth. 



The true legs exceed the arm in length almost by their last two 

 joints. 



The male abdomen resembles that of the last species, and its long 

 second piece has a stout tooth at its extreme distal end. 



The carapace of the male measures 7"5 by 65 millim., that of the 

 female 8 by 7 millim. 



Colours in spirit : uniform yellowish pinkish brown. 



In the Indian Museum collection are 2 males (one adult) and 6 

 females (four ovigerous) from the Andamans, and an adult male from 

 off Cape Comorin, 39 fathoms.

Pseudophilyra pusilla, Henderson, Trans. Linn. Soc. Zool. (2) V. 1893, p. 398, 

 pi. xxxvii. figs. 13-15. 



Differs from Pseudophilyra wood-masoni in the following particulars 

 only :— 



1. Its size is even more diminutive, the carapace of the largest 

 male in the Indian Museum — an undoubted adult — measuring 6 by 5 

 millim. 



2. The edge of the front is straight, slightly deflexed and concave 

 in the middle line, this deflexed portion being again produced horizon-
