Genus TELLIDORA Morch.

This fine genus is often quoted as of Morch, " 1851," but Dr. Morch pub- 

 lished nothing in 1851 and his publications of 1850 and 1853 contain no refer- 

 ence to this genus. I have not been able to find any earlier citation of it than 

 that given in the " Genera of Recent Mollusca" cited above, though it is possible 

 the name may have been mentioned by some correspondent of Morch in some 

 anterior publication which I have not discovered. 



The group is linked to Tellina by such forms as Phyllodina. 



Tellidora cristate, Re'cluz.

 Tellidora cristata Dall, Bull. 37, U. S. Nat. Mus., p. 62, 1889. 



Pliocene of the Caloosahatchie and Shell Creek, Florida; Pleistocene of 

 the Carolinas ; recent from North Carolina southward to Campeche and 

 Trinidad Island. 



This is closely related to the T. Burneti, but is less compressed and the 

 flatter valve is the left one, while in T. Burneti it is the right. 



Tellidora Burneti Broderip and Sowerby. 

 Tcllina Burneti Brod. and Sby., Zool. Journ., iv., p. 362, pi. ix., fig. 2, 1839; Cpr. Maz. 



Cat., p. 39, 1857.

Holmes, P.-P1. Fos. S. Car., p. 48, pi. ix., fig. 6, a-b, 1858. 



Pleistocene of Lower California (Hemphill) ; recent in the Gulf of Cali- 

 fornia and southward to Panama. 



Carpenter states, on the authority of Woodward, that " a species of similar 

 form is found fossil in the Palaeozoic rocks, agreeing more with the Atlantic 

 shell" (Maz. Cat., p. 39), but this must refer to some Pelecypod not congeneric, 

 since the oldest Tellinidw do not pass below the Lower Cretaceous, and Telli- 

 dora is not known in any beds older than the Pliocene.
