to anterior border of pupil of lower eye. Teeth small, conical, 

 closely apposed; strong on the blind side, very weak and few on the 

 opposite side; located in a single row with occasionally an irregular 

 one. Gillrakers on first arch 2 + 5; those on upper limb scarcely evi- 

 dent, the lower ones short, flat, blunt, and widely spaced. Nostrils 

 tubular. 



Lateral line with a very abrupt arch which at its highest point is 

 about eight scales above the horizontal, with an accessory branch 

 which does not extend backward as far as the gill opening. A con- 

 spicuous ventral branch extends downward and forward beneath the 

 eye to the maxillary. Scales weakly ctenoid, this character appear- 

 ing as distinctive when the species is compared with L. hilineata; 

 those of opercles minute and closely crowded; occipital space with 

 but a single row of minute scales; all the fin rays except the pectoral 

 on the blind side with minute scales; edge of preopercle naked. 



Dorsal originating above anterior edge of pupil; longest rays con- 

 tained about two times in head. Highest anal rays equal in length 

 to those of dorsal. Caudal rounded, 1.2 in the head. Pectoral 1.8 

 in head; that of blind side about 3 in head. Ventrals rather stout, 

 the ra}^s heavy, 3 in head. Base of anal preceded by a short, strong 

 spine that protrudes through the skin. 



Color in spirits pale brown. 



Two specimens were procured in the market at Otaru, Hokkaido, 

 one of which, measuring 208 mm. in length, is selected as the type, 

 Cat. No. 68245, U.S.N.M. The other, measuring 145 mm., is recorded 

 in the Stanford University collection as cotype No. 21430.

GLYPTOCEPHALUS SASjE, new species. 



This species has a deeper and more robust body than G. zachirus, 

 and it also differs from that species in having a shorter, rounded 

 pectoral and a much weaker anal spine, which does not appear to 

 protrude from the skin. It differs markedly from G. zachirus and 

 also from G. cynoglossus, the Atlantic form, in having but 49 vertebrae. 



Head 4.8 in length to base of caudal; depth 2.9; depth caudal 

 peduncle 11.5; eye 3.5 in head; snout 4.1; maxillary 5.2; D. 90; 

 A. 77; pores in lateral line about 109; transverse series of scales 

 about 113. 



Body dextral, the snout rather blunt; mouth small; the maxillary 

 extending but little beyond anterior margin of eye, that of the blind 

 side almost a third longer. Lower eye advanced in position, its pos- 

 terior border touching a perpendicular through edge of pupil of upper 

 eye; interorbital space broad, almost equal in width to half the 

 vertical diameter of lower eye. Anterior nostril with a short tube. 

 Teeth present on both sides of the jaws, in a single row, closely
