Vertical range. — Off the Irish cx)ast this species has been 

 found between 8 and 230 fathoms ; in Indian waters it is re- 

 corded from 200 to 250 fathoms ; in the Bay of Biscay it has 

 been trawled by the Huxley in 412 fathoms ; while in the Medi- 

 terranean it is stated to have occurred in 543 fathoms (Aden- 

 samer). Post-larval specimens, up to 30 mm. in length, are 

 frequently caught in midwater and less commonly at the sur- 

 face. Although the adult is occasionally found under similar 

 conditions, there can be little doubt that it lives normally on, 

 or very near, the bottom.

The rostrum is in the form of a procurved post-frontal spine 

 rising from the dorsal carina ; the apex usually reaches slightly 

 beyond the anterior margin of the carapace. The carapace 

 is slightly less than half the length of the abdomen (excluding 

 the telson) and its greatest depth is about half its length. As 

 in P. sivado it is furnished with a sharp spine at the base of 

 the antennae above the obtusely rounded sinus. A carina de- 

 fines the superior boundary of the branchial chamber, disap- 

 pearing before it reaches the posterior margin. 



All the abdominal somites are sharply carinate dorsally with 

 the exception of the posterior third of the sixth ; this somite 

 is about one and a half times the length of the preceding and on 

 each side of it a rather conspicuous carina may be seen. The
