The type of this genus is A. hoops Agassiz. The type speci- 

 men of this species is practically the only known example. 

 It is refigured in Dr. Woodward's publication of 1902, cited 

 above. Unfortunately this author has not figured his A. 

 lihanicus, from the Cretaceous of Sahel Alma. The following 

 species i§ believed to be congeneric with the one described 

 from Sahel Alma, but it is doubtful if either belongs to the 

 genus Acrognathus.

The type of this species is No. 4520a (3673). It has a total 

 length of 88 mm. ; to the base of the caudal fin 68 mm. The 

 head and the opercular region together measure 20 mm. The 

 depth is 21 mm. The rays of the dorsal fin are somewhat 

 confused, but there appear to be 12 interneural supports. 

 The pectoral fin is wanting in the specimen. The ventrals 

 are slightly in front of the origin of the dorsal, but this is 

 probably due to slight displacement. The rays are stout. 

 The anal is somewhat damaged, but it was evidently short. 

 The vertebrae number 32 or 33. The scales are thick. 



The premaxilla is furnished with small teeth. The man- 

 dible is high posteriorly. Its length is 10 mm. The articu- 

 lation is brought forward to beneath the eye. 



At the base of the caudal fin, both above and below, are 

 about half a dozen reduced rays, and these are preceded by 

 a very short, but stout, modified ray, which appears to have
