The rostrum and carapace of the largest specimen are 39 millim. long; the 

 abdomen fully-extended, is 51- millim. long, the measurements being taken in Hu- 

 mid-dorsal line. 



Common off tho Coromandel coast in H8-250 fathoms, also found off the 

 Malabar coast in 124-119 fathoms. 



This species is as closely as possible related to P. pli!l!i>]>inftitit 8p. Bate, with specimens of 

 which I have compared it. The only differences l>etween the two species are the following: in 

 P. pliUippinensis the rostrum is strnighter, there is no nn^uhition of the 4th and 5th' abdominal 

 t,ergit on either side of the median carina, there is no tooth (tlionpli there is a slight concavity) 

 near the base of the inner antennnlnr flagellum on its inner-npper border, and thoujyh the posterior 

 border of the " tholycum " is curved something like a u> the middle limb of the <o is long broad and 

 squave-cnt.

This variety differs from P. coniger in the following particulars only : 



(1) the rostrum, though uptilted, is nearly straight : (2) the subcarina- on 

 either side of the median carina of the 4th and 5th abdominal terga are indis- 

 tinct : (8) the posterior border of the "thelycum" is deeply undermined, it is 

 curved like a <u reversed, but the middle limb of the is long and very broad and 

 recurved at its free end : (4) the " andricum " of the 1st abdominal appendages 

 is at least half as long as the carapace (without the rostrum). 



In the largest specimen the rostrum and carapace are 50 millim. long and 

 the extended abdomen is 76 millim. long, measured in the mid-dorsal line. 



Common in the Andaman Sea between 100 and 244 fathoms : also taken 

 once, in large number, off Cape Comorin in 143 fathoms.

Glabrous. Rostrum with a very slight double curve, armed dorsally with 

 12 or 13 teeth not including a tooth on its gastric carina : in the female its free 

 portion is not quite three-quarters tho length of the rest of the carapace 

 measured in the mid-dorsal line and its tip reaches to the far end of the unten- 

 milar peduncle, but in the male its tip falls short of the end of the antcnnular
