Selanoninx, Fleming, Briti.sli Animals, 169, 1S28, {walJceri = coniubicits). 



Body short aud stout, the back considerably elevated ; snout prominent, 

 pointed; teeth triangular, pointed, entire, each one with a small cusp on 

 each side at base; one or both of these sometimes obsolete on some of 

 the teeth in the young; gill openings wide; dorsal and j)ectoral fins some- 

 what falcate; second dorsal and anal fins very small, nearly opposite 

 each other; first dorsal close behind the root of the pectorals. This 

 genus is very close to Jsmj'ms, with which fossil forms seem to connect it. 

 Perhaps the two should be united under the older name Isurus. {Aa/xva, 

 a kind of shark, from Innia, a horrible anthropophagous monster, a 

 bugbear used by the Greeks to frighten refractory children.)
