(Plate VIII, fig. 4) 



Type a small fish ( No. IX ) , two inches long, from the diatomaceous 

 shales of El Modena. Coll. E. E. Hadley. It has the head distorted, 

 the fins partly obliterated, and the body with a short median break. 

 Head 3% in length; depth 4; a little greater than length of head. 

 Snout 3 in head ; vertebrae 9 -(- 16, visible, about 26 in all, perhaps two 

 or three others obscured with the head; vertebrae strong, with strong 

 neural and haemal spines, directed strongly backward. Body lanceolate, 

 the back somewhat elevated under the first dorsal. Head large, apparently 

 pointed anteriorly; the jaws apparently equal; the mouth rather large,
