broad, depressed or flattened, and trifle wider than long. Eye 

 large, little elevated, a little anterior. Adipose eyelid not developed. 

 Mouth broad, terminal, with short commissure about half way in 

 snout length. Maxillary small, thin, about f in snout. Lips thin, 

 and rather firm cutaneous edges without cilia. Tongue not distinct. 

 Jaws about even, rami wide and little elevated in mouth. Nostrils 

 together, about last third in snout length, anterior simple pore and 

 posterior in crescent. Interorbital broad, flat. Preorbital rather 

 narrow, equals long infraorbital, both smooth. Preopercle con- 

 current with infraorbital and cheek thus covered entirely by last. 

 Opercle large, smooth. Occipital fontanel broad, uninterrupted 

 from internasal space to occiput. Occipital process short and 

 equilaterally triangular. 



Gill-opening extends forward about midway in eye. No gill- 

 rakers. Filaments about half of eye. Isthmus narrowly constricted, 

 convex. 



Scales large, cycloid, exposed edges entire, attached edges usually 

 with 3 lobules. Scales of mostly uniform size, though a little smaller 

 on caudal base. Scales on isthmus slightly smaller than those on 

 breast, and latter equal those on sides of body, also of uniform size 

 over their area. Ventral with small axillary pointed scaly flap. 

 L. 1. complete, straight, inclined parallel with axis of body from 

 shoulder to caudal base medianly. Tubes simple, and about equally 

 developed anteriorly as elsewhere. Hind edge of each scale in 1. 1. 

 with slight notch. ^ 



Dorsal origin midway between snout tip and origin of adipose fin, 

 and apparently front rays little longer than others (fin damaged). 

 Adipose fin slender, about long as eye. Anal inserted well before 

 front of adipose fin, or about midway between ventral origin and 

 caudal base, front rays longest (fin damaged). Pectoral short 

 (damaged). Ventral inserted about opposite middle of dorsal base, 

 iin pointed and nearly reaches anal. Vent close before anal. 



Color in alcohol brownish, paler on sides of head and body, and 

 lower regions, where also with slightly silvery tinge. Iris whitish. 

 Including 1. 1. for width of its scales its entire extent paler band. 

 Caudal blackish basally, or spot thus formed about equal to eye, 

 and but slightly reflected on median rays for a short space. Fins 

 pale brownish. 



Length 38 mm. (caudal damaged).
