176 ALBATROSS EXPLORATIONS, FISHES— JORDAN AND BOLLMAN. 



large black spots some what smaller than eye ; these are regularly four 

 below dorsal aud two above anal, the first of dorsal above arch of lat- 

 eral line, the second above anterior third of straight part, the third at 

 base of last rays and almost forming a cross-bar with the one at base 

 of aual rays. 



Dorsal, anal, aud caudal dusky, with small whitish spots; a pale' 

 spot at base of last four dorsal aud anal rays ; a small black spot at 

 base of outer caudal rays on peduucle. Pectorals and veutrals dusky, 

 but not spotted. Eight side immaculate. 



Numerous specimens were dredged at Station 2805, at a depth of 51£ 

 fathoms. 



Engyophrys gen. no v. 



Allied to Platophrys (Swainson), but haviug the iuterorbital space 

 very narrow and armed with a spine, and the scales of moderate size 

 and cycloid. Gill rakers obsolete. No anal spiue. Gill membranes 

 entirely separate. 



It is nearest the genus Engyprompon Gunther, but in that group the 

 iuterorbital space is broader, the scales cteuoid, aud the gill-rakers de- 

 veloped. 



Type: Engyophrys sancti-laurcntii. 



30. Engyophrys sancti-laurentii * sp. nov. 



Diagnosis. — This peculiar species is distinguished from species of 

 Platophrys and Engyprosopon by its very narrow iuterorbital ridge ; from 

 the species of Arnoglossus by the form of the body, the short gill- 

 rakers, etc.; and from all related species by the peculiar coloration of 

 the blind side. 



Type: No. 41,155, U. S. National Museum. 



Hab. — Pacific Ocean, off coast of Colombia ; from Station 2805, 7° 

 56' N., 79° 4P 30" W., and Station 2795, 7° 57' N., 78° 55' W. 



Description.— Head 2| to 2| (3 to 3i) ; depth 1| to 2 (2 to 2£). D. 78 

 to 85; A. 68 to 72. Scales GO to dS, along lateral line. Length of type 

 4£ inches. 



Body broadly ovate, much compressed, the greatest depth over pec- 

 torals; dorsal aud ventral outlines equally curved; profile scarcely 

 concave before eyes. Mouth very small, oblique, the maxillary reach- 

 ing opposite pupil of lower eye, 4 to 4i in head. Teeth present on 

 blind side well developed, close set, and even; none on vomer. Snout 

 short, 4£ to 5 in head. Interorbital space a very narrow, sharp, scale- 

 less ridge, the ridge forking above pupil, leaving a very narrow con- 

 cavity anteriorly ; lower ridge armed with a strong spiue, turned back- 

 ward, inserted just above pupil of lower eye. Anterior orbital rim of 

 upper eye rather high, enteriug profile. Eyes large, lower in advance 



In allusion to the gridiron-like markings on the blind side.
