BEACHIOPODA OF THE MAEL BEDS. 1 1 



jority, but not sufficiently so to be specifically distinct. The young* shells 

 of this species differ from T. lachryma Morton, in being less ventricose on 

 the umbo, less elongated in form, more circular in outline, with a shorter 

 and broader beak. They must very closely resemble T. floridana Morton, 

 from the Cretaceous at Prairie Bluff', Ala., but, as I have no specimen from 

 that locality for comparison, I am not able to assert positively in what par- 

 ticulars they differ. If they prove to be indentical, the name T. floridana 

 will have precedence over that of T. atlantica. 



Formation and locality,— k\\ the specimens which I have seen, and of 

 which I have been able to ascertain the localitv w^ithout doubt, have been 

 from the lower beds of the upper marls. The form given by Conrad as T. 

 glossa, I have seen from Farmingdale in the collection of Miss F. M. Hitch- 

 cock, of New York City (Plate l,fig. 13). The example figured on PI. l,fig 

 10, is from the collection of Dr. L. Johnson, of New^ York, and is also from 

 Farmingdale. Other and smaller specimens, but showing the same features, 

 except in being less gibbous, are from the same horizon at Shark River, N J., 

 Columbia College collection. I do not remember to have seen any speci- 

 mens authentically derived from either a higher or lower locality. Mr. 

 Conrad's examples of T, glossa were from Shark River. Mr. Gabb gives for 

 T. Halliana simply ''New Jersey." Dr. Morton cites for his specimen the 

 ''ferruginous sands at Woodward's farm. New Jersey, found by Mr. Con- 

 rad"

This species was originally described from the Cretaceous formations 

 at Prairie Bluff, Ala., but is given by Mr. Meek as a New Jersey species in 

 his catalogue in the Geological Survey of New Jersey for 1868, p. 729. 

 So far I have not observed it among the fossils of this State, and am inclined 

 to think the reference an error. Young individuals of T, Halliana (Gabb) 

 =: T, atlantica (Morton) have very much the characters of the Alabama 

 shell, but they differ in being more elongate, less broadly rounded, and in
