acuminate in front, nearly two and a half times as long as their 
maximum breadth. Scales large and thick, covered with even 
rounded ridges forming a complete reticulation.

/ 1866, is now iu the Elgin Museum.

Type. Head, pectoral fins, and anterior abdominal region, ventral 
aspect; Lehigh University, Pennsylvania. 
A species closely related to G. minor, known only by the type 
specimen. The “ triangular accessory jugulars of G. minor noted 
by Newberry are the infraclavicles, met with in all Crossoptery- 
gians sufficiently well preserved. 
In this fossil the lateral jugular plates are shown, and it is 
suggested (op. cit. 1889, p. 118) that if such plates eventually prove 
to be absent in the typical G. minor, the fish may be regarded as 
representing a distinct genus, Glyptognathus. /
