1 inches. Pacific coast of Colombia. Numerous specimens were dredged 

 at Albatross Station 2805, at a depth of 5H fathoms. This species differs 

 from Hippoglossina stomata in the gill rakers, which are shorter and fewer 

 in number, 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 

 somewhat shorter, 8 or 9 on anterior limb, 2 on upper 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 squamation agreeing per- 

 fectly with H. stomata. (Named for Charles Harvey Bollnian.)

Lioglossina, GILBERT, Proc. TT. S. Nat. Mus. 1890, 122 (tetrophthalmus). 



This genus is allied to Hippoglossina, but its scales are all cycloid, the 

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

 and thick. (Azoj ; smooth; Tt\(!b66a, tongue; for Hippoglo&slna.} 



2989. LIOGLOSSINA TETROPHTHALMA, Gilbert. 



Head large, 3J 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 

 angulated above upper pupil, the snout projecting; length of caudal 

 peduncle \ its depth, its outlines diverging backward ; depth of body 2 

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

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

 posterior border of lower eye, 2 in head; a blunt projecting 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 upper; vertical from front of upper falling midway 

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

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

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

 less, its width f 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 pupil 

 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, | length of head; ventral 

 6. Scales rather small, growing distinctly larger posteriorly, everywhere 

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

 of maxillary, the latter with a patch of scales on posterior end of its 

 expanded portion; on blind side an area around nostrils, and the greater 

 part of exposed portion of preorbital, scaleless; fin rays of vertical fins,
