Fig. 2. — Synodus dominicensis Fowler. Type. 



Body elongated, rather slender, apparently deepest about dorsal 

 origin and though trunk now compressed this may be due to pre- 

 servation?. Trunk seems to taper each end from greatest depth- 

 Caudal peduncle now compressed, least depth half its length. 



Head elongated, depressed above, lower profile little more evenly 

 convex than upper, sides somewhat constricted below. Snout with 

 slight concave profile, depressed, surface generally convex, length 

 about f its basal width. Eye a little ellipsoid, impinging on upper 

 profile, about first f in head. Mouth large, a little inclined. Pre- 

 maxillary slender, extends beyond eye about | eye-diameter, and 

 greatest expansion about 6 in eye. Lips thin, not concealing entirely 

 single series of erect firm sharp compressed elongated premaxillary 

 teeth. Another series of similar longer depressible teeth along 

 upper jaw edge inside maxillary series. Mandibular teeth similar, 

 triserial, outer series smallest and firm, and 2 inner series depressible 

 with innermost largest. Teeth not united across symphysis of
