TRANSACTIONS OF WAGNER 



1484 



TERTIARY FAUNA OF FLORIDA 



end hardly rostrate ; hinge normal, basal margins finely crenate ; adductor 

 scars slightly raised. Length 18.0, height 15.2, diameter 8.0 mm. 



The nepionic shell in this species is smaller and smoother and the ribbing 

 of the disk less coarse than in the other species. The rostration, which is so 

 marked a feature in L. tellinoides, is not found in this or the lower Eocene 

 species.

This form appears to be very mutable, and the consolidation above indicated 

 is suggested on the basis of specimens named by Professor Harris in the collec- 

 tion of the National Museum. 



The A. smithvillensis of Harris is said to be the A. Conradi Buckley, 1874, 

 not of Dana, " Manual of Geology," 1863. 



The genus Goodalliopsis De Raincourt and Munier-Chalmas, 1863, which 

 is placed by Fischer in the Astartidce, should be transferred to the Erycinida 

 (as a synonym of Kellia), as previously indicated by Cossmann. Bernayia 

 Cossmann, 1887, accidentally omitted from my review of the Leptonacea, 

 should also, from the figures, belong in the vicinity of Kellia. 



A careful examination of the type of Plesiastarte Fischer, 1887, leads to 

 the conclusion that Deshayes in referring it to the Cyrenida had much justifica- 

 tion. It has none of the characteristics of the Astartida. On the other hand, 

 a little shell described by Gould from Japan, under the name of Gouldia dilecta, 

 has identically the same hinge characters, except that the lateral lamina is not 

 cross-striated. I suspect the latter to be the very young shell of some Venerid 

 allied to Meretrix. 



I have not been able to examine authentic specimens of the Mesozoic Prtz- 

 conia Stoliczka, 1871, and P achy ty pus Munier-Chalmas, 1887. ParisieUa 

 Cossmann, 1887, from the Parisian Eocene, is also only known to me by
