TRANSACTIONS OF WAGNER 



TERTIARY FAUNA OF FLORIDA 



in Favanne's collection, both of which are figured in the atlas to Bosc's work. 

 Lamarck without ceremony refers Bosc's figures to Alya arctica Linne, and 

 cites but that single species under the genus. Dr. Gray cites Hiatella arctica 

 from Daudin's memoir of 1800, but without mentioning page or figure for it, 

 which leads to the suspicion that he may not have actually seen the paper 

 himself. If his citations be correct, there would seem to be no doubt that 

 Hiatella should be adopted in place of the later Saxicava, but in the doubt 

 that remains I hesitate to make the change, and would prefer to leave it to 

 some one who can consult the original memoir.* Brown in 1827 (111. Conch. 

 Gt. Brit.) takes the same course that Gray did later with regard to the two 

 names, but the Hiatella of Costa, 1828, is the same as Galeomma Turton, 

 1822.
