Standard length. The dorsal spines in both P. rctvosp'mis and P. Iicrrei 

 are 6 in number, Fowler having overlooked the hidden sixth spine 

 in these specimens.

Ilolotype. — U.S.N.M. no. 93186 (Field no. 16) ; from Caroline 

 station i, ofif Punta Boca Juana, north coast of Puerto Rico, latitude 

 i8°33'45" N., longitude 66°r5'oo" W., January 30, 1933, large otter 

 trawl, 360 to 600 fathoms. 



Dorsal VII — 19. Anal 19. Scutes in the upper of the two lateral 

 series 33. Lower lateral series of scutes not breaking up into two rows 

 anteriorly, behind the appressed pectoral fins. 



Head and snout broad. Width of snout (including flanges), at base 

 of rostral processes, equal to snout length and greater than length 

 of processes. Rostral processes long, narrow, of almost equal breadth 

 throughout their length, diverging, their bases far apart, their length 

 2.25 times in distance from their base to posterior termination of main 

 cephalic flange. Interorbital equal to horizontal diameter of bony orbit. 

 Cephalic flange well developed along its entire length, its margin more 

 or less regular, not strongly emarginate near its end, truncate at its 

 posterior termination. Supplementary ridges below flange well devel- 

 oped, low, not produced outward beyond flange at any point. Greatest 

 width of head (including flanges) much greater than its greatest 

 depth. Anterior pair of ventral thoracic plates short and broad, not 

 extending as far forward as do the bony processes before each pelvic
