Oligocene of Bowden, Jamaica. 



This species is not unlike Philippi's L. textilis, also a Jagonia, a recent 

 species. From C. pertenera Dall it differs in smaller size, more inflated and 

 solid shell, stronger radials and marginal crenulation, and, in some specimens, 

 distinct reticulation of the sculpture. I have some suspicion, however, that 

 the two forms may prove to be extreme mutations of a single specific type, and 

 for that reason do not propose a new specific name for the smaller fossil, which 

 in that case would only form a dwarfish variety of C. pertenera. Some very 

 young shells from the Oligocene at Gatun, Isthmus of Panama, may be nepionic 

 specimens of the same species.

Oligocene of the Bowden marl, Jamaica, West Indies. 



This is the Oligocene analogue of the recent Lucina antillarum Reeve 

 (=L. costata Orbigny, not Tuomey and Holmes), from which it differs in 

 its more inequilateral shell, sharper and more distinctly reticulate sculpture, 

 with finer and more thread-like radials, plumper and usually smaller shell. It 

 is abundant in the Bowden marl, from which it was collected by Henry Ven- 

 dryes, Esq., who sent it to Mr. Guppy, and subsequently by Messrs. Henderson 

 and Simpson. 



Codakia (Jagonia) erosa n. sp. 



PLATE 52, FIGURE 7. 



Oligocene of the Chipola marl, Chipola River, Florida ; Burns. 

 Shell small, slightly inequilateral, moderately plump, suborbicular ; beaks 

 small and prominent ; surface sculptured with a dozen or less obscure, hardly 

 elevated, broad, flattish radials, corresponding to fascicles of radial threads in 

 C. Vendryesi, crossed by incremental lines and near the base by somewhat 

 more widely spaced concentric grooves; lunule lanceolate, moderately im-
