118 DEEP SEA FISHES. 



equal to that of the skull across the parietals. In the upper and longer 

 l)ortion of the fin there are fifteen rays ; this portion is separated by an 

 interspace with four short rays, distant from one another, from tlie lower 

 portion of the fin, which contains five raj's nearly as long as those in the 

 Tipper part. The shortest rays of the pectorals occup}- a space the width of 

 which is about equal to the length of the orbit ; they are connected by 

 membrane. The longest rays are nearly or quite as long as the longest of 

 those of either dorsal or anal. Accurate determinations of the numbers 

 of rays in the vertical fins, or of the shape and connections of the caudal are 

 prevented by the condition of the specimen. 



Total length ten inches or more. 



Dark brown or black. 



The structure of the pectoral most likely agreed with that figured for 

 P. hathyhius in the " Challenger" Report by Glinther in having the low mem- 

 brane between the sections of the fin, but with the addition of short raj-s in 

 support, which may not have protruded beyond the edge, as in the figure 

 given by Collett.

Total length equal to three and one fourth times the lengtli of the 

 body cavity. Body compressed, depth about one sixth of the total lengtli ; 

 caudal section very long and slender. Head less than one seventh of the 

 total, one fourth deeper th.an wide, high at the najie, curving downward in 

 front in a broad arch, flattened or slightly convex on the crown and fore- 

 head, narrower and rounded and blunt on the snout ; interorbital space 

 little, if any, wider than the eye, narrowing rapidly in front. Snout some- 

 what produced above and forward of the mouth, hardly as long as the eye. 

 Mouth medium, horizontal; maxillary not reaching a vertical from the hind 

 border of the orbit. Teeth small, simple, short, acuminate, not numerous, 

 in single series, stouter and broader toward the base than those of P.fim- 

 briatus. Eye large, one and one third times the length of the snout, 

 orbital length nearly equal to the width of the interorbital space. The
