P. demani was hitherto known only from the Chilka Lake in 

 Orissa and from the Adyar R. and Ennur backwater near Madras. 

 In the Chilka Lake it has been found living in water ranging in 

 specific gravity from i - ooo to T0265.

I have seen the type of this species in the Cambridge Museum, 

 but have not dissected it to examine the mandible. It is the only 

 known species of the genus in which the supra-orbital spine is 

 present and the hepatic absent. 



The antennal scale is not much narrowed apically ; the outer 

 margin is concave and the terminal spine extends beyond the apex 

 of the lamella. The merits of the second poraeopods bears a 

 spine at the distal end of the lower margin. Only one of the 

 posterior legs is in existence ; it is very stout, with the propodus 

 only about 4 times as long as broad and with the dactylus simple, 

 strongly curved and partially concealed by thick hairs. The telson 

 bears two pairs of dorsal spines, placed rather close together near 

 the middle of its length. 



P. lifuensis is known only from Iyifu in the Loyalty Is.

The rostrum varies greatly in length ; in the specimens I have 

 examined it is from i'6 to twice the length of the carapace, while 

 in the large male described by Borradaile as P. kolumadulensis it 

 is said to be 2*5 times the length of the carapace. The rostrum is 

 very slender, straight at the base, but with the distal half bent 

 obliquely upwards. It bears from*t) to 12 teeth (nearly always 10 

 or 11) ' on the upper border ; the posterior tooth is placed on the 



' Ol thirty-two specimens two have 9 dorsal teeth, twelve have id, seventeen 

 have 11 and one has 12.
