 Junction Cliff; Div. 1, A. G. 



Genus Glossoceras, Barrande. 



Gr. DESIDERATUM, n. sp. — This species is founded upon a fragment con- 

 sisting of two of the lateral chambers and the impression of about two 

 inches in length of the body of the shell. The form appears to be elongate 

 sub-cylindrical, section, about the middle, broad ovate, the dorso-ventral 

 diameter greater than the lateral ; the latter, in this individual, fourteen 

 lines. The inner side of the chambers is gently concave, the lower edge 

 broadly rounded, the upper edge concave. The outer side is convex con- 

 forming to the form of the shell. Length of the upper of the two chambers 

 on the inner side nine lines in length and twelve lines in width ; the 

 lower ten lines in length and eleven in width. The specimen is so imperfect 

 that it should not perhaps be named, but as there is a prospect of further 

 collections from its locality it is probable that materials will soon be forth- 

 coming to complete the description. South-west Point ; Div. 4, A. G. J.
