anteriorly ; width of head, 2 in its length; depth of head 1; snout 
6; eye 334; maxillary 314; mandible 27; interorbital space 4; 
first developed dorsal ray 17%; lower caudal lobe 1; first devel- 
oped anal ray 256; pectoral 1%; ventral 2; least depth of 
caudal peduncle 2% ; base of anal 324 in head and trunk. Body 
compressed, rather déep, somewhat ovoidly rhomboid, and great- 
est depth about origin of dorsal. Nuchal and thoracic regions 
bulging a little on anterior profiles. Caudal peduncle com- 
pressed, its least depth equal to its length, from base of last anal 
ray. Head rather small, compressed and deep, obtuse in front. 
Profiles similarly inclined. Snout short, obtusely convex in pro- 
file, and somewhat compressed. Eye rather large, anterior, cir- 
cular, and about midway in depth of head. Adipose eyelid well 
developed, the exposed portion of eye a little less than half its 
diameter. Mouth a little inferior, upper jaw produced beyond 
mandible, and maxillary reaching about opposite front margin 
of pupil. A groove along side of mandible obliquely back from 
below posterior extremity of maxillary. Teeth in narrow bands 
in jaws, and minute. Vomer and palatines edentulous. Tongue 
rather large, triangular, thick, free marginally, but with median 
frenum extending well forward so that it is adnate with floor of 
mouth. Rami of mandible well elevated inside of mouth. Nos- 
trils together, lateral, and near front margin of eye. Upper 
surface of head adipose-like over eye, and interorbital space well 
elevated convexly. Symphysis of mandible with a tubercle, fit- 
ting in a depression in upper jaw when mouth is:closed.  Gill- 
opening extending forward till not quite opposite front rim of 
pupil. Rakers 135 + 110?, fragile, slender, short, longest */; 
longest filaments which are a little shorter than orbital diameter. 
Pseudobranchiz nearly twice as long as longest rakers. Isthmus 
a little broad, with flattened surface. Scales large, narrowly im- 
bricated, cycloid, and forming nearly horizontal series, those in 
front of dorsal not completely crossing over, but leaving a nar- 
row naked strip medianly on back. Head naked. Abdomen 
medianly from gill-opening to vent with 30 robust keeled serra- 
tures. Fins naked, except base of caudal, which is covered with 
small scales. Small scales along base of anal forming a low
