7 inches. Pacific coast of Colombia. Numerons specimens were dredged 

 at xUhaiross Station 2805, at a depth of 51i fathoms. This species differs 

 irom JIi2)poglossiiia slomata in tlie gill rakers, which are shorter and fewer 

 in niimber, and in the larger .scales on sides. Scales in 16 rows between 

 lateral line and back, instead of 21 or 22, as in H. stomata. Gill rakers 

 somewh.it shorter, 8 or 9 on anterior limb, 2 on npper limb. In H. macrops 

 the gill rakers are slender, close set, 13 or 14 on anterior limb, 4 on vertical 

 limb. In other respects of color, fin rays, and sqnamation agreeing per- 

 fectly with //. stomata. (Named for Charles Harvey Bollman.)

This genns is allied to Hippoglossina, bnt its scales are all cycloid, the 

 teeth are small, pointed, nniserial, and uniform, and the gill rakers short 

 and thick. (Aezoj, smooth; TtX&dd a, tongue; iov HippogJossbia.)

Head large, 3^ in length in a specimen 1 foot long. D. 76 to 83; A. .58 to 

 62 ; lateral line (pores) 97. Body of moderate height, the profile distinctly 

 angnlated above npper pupil, the snout projecting; length of caudal 

 peduncle I its depth, its outlines diverging backward; depth of body 2J 

 in length; snout projecting beyond prolile, bluntly rounded, the lower 

 jaw included. Mouth large, the maxillary reaching nearly to vertical from 

 posterior border of lower eye, 21 in head ; a blunt jirojecting process ante- 

 riorly from head of maxillary. Teeth small, pointed, in a single close-set 

 series in each jaw, none of them enlarged; vomer toothless; lower eye 

 slightly in advance of npper; vertical from front of upper falling midway 

 between front of orbit and front of pupil of lower eye; vertical diameter 

 of upper orbit bnt little more than ^ its longitudinal diameter, which is 

 contained 3i in head ; interorbital space a blunt high ridge, entirely scale- 

 less, its width 'i diameter of orbit. Anterior nostril of blind side with a 

 very long flap, that of eyed side shorter; a well-marked cutaneous flap on 

 lower eye above pupil. Gill rakers very large, broad, and strong, well 

 toothed on inner edges, longest equaling diameter of pupil, the number 

 on outer gill arch 10 or 11. First dorsal ray over anterior margin of pnpil 

 of upper eye, the fin not high, its highest ray 3 in head; anal similar; 

 caudal sharply double truncate, the median rays produced; ventrals 

 rounded, equal, barely reaching front of anal ; no spine before anal fin ; 

 pectorals moderate, with 9 or 10 developed rays, i length of head; ventral 

 6. Scales rather small, growing distinctly larger x>osteriorly, everywhere 

 smooth; head scaled, except snout, interorbital area, mandible, and part 

 of maxillary, tlie latter Avith a patch of scales on posterior end of its 

 expanded porti(m ; on blind side an area around nostrils, and the greater 

 part of exposed portion of i)reorbital, scahdess; fin rays of vertical fins,
