Pseudoscyynnus Hekre, Copeia, No. 3, p. 124, fig. 2, 1935. (Type, PseuOosoymnits 

 hoshuensis Herre, orthotypic.) 



Body elongate, fusiform : Groove on each side from above pectoral 

 origin to above ventral. Head rather small, somewhat depressed, 

 flattened above. Snout short, broadly rounded. Eyes large, elongate, 

 without nictitating membrane. Mouth gently arched, with very 

 long labial fold concealing each angle. Teeth unlike in two jaws 

 18 rows in each. Upper teeth slender, pointed, several rows func- 

 tioning. Lower teeth broad, with single, triangular serrate cusp 

 on a broad and long base, slightly oblique, but one row visible. Nos- 

 trils very far forward. Gill openings narrow, in front of pectoral. 

 Spiracle large, transverse, on top of head well behind eyes. Scales 

 on lower side of snout conspicuously larger than elsewhere, simple, 

 smooth, triangular, imbricate. Elsewhere scales minute, closely ap- 

 pressed, widely spaced, more or less keeled, and trifid with long 

 central point and with 2 lateral points at right angles to central 

 one. Fins small. Dorsals without spines, first between pectorals and 

 ventrals and origin of second over hind part of ventrals. 



Distinguished by its serrate lower teeth, position and character 

 of fins, and in the presence of two kinds of scales.
