Recent on the Florida coast and northward to the Carolinas. Fossil, 

 Caloosahatchie beds. 



As Mr. Gabb observed, it is almost impossible, without the color-markings, 

 to identify cones ; and, therefore, identifications must always be taken as 

 approximate. But I cannot join him in uniting C. Pealii with Sowerby's 

 much larger and coarser species. The identification, from Green's specimens, 

 ofC. Pea/ii and C. Stear?isii, was made by Dr. Stimpson; from the description 

 alone one would suppose Green was dealing with a young specimen of C 

 pygincBiis Reeve or some other species. However, the species now known as 

 C. Pealii, as reinstated by Stimpson, would keep its name at any rate, since 

 Green's name is much older than Sowerby's. It is probable that the shells 

 referred to C. planiliratiis by Mr. Gabb included specimens of several species, 

 but C. Pealii, not being known from the Antilles, was probably not one of 

 them. The Caloosahatchie shells in form and sculpture agree absolutely with 

 fresh specimens of C. Pealii, so I cannot refer them elsewhere. 



Conus centurio, C. Delessertii, C. flavescens and C. floridanns, deprived of 

 color, cannot be specifically separated from each other. In the recent state 

 the forms are easily recognizable, and by comparison of a large number of 

 specimens one can generally recognize a certain facies, undefinable but 

 existent, which gives probability to one's identification of the colorless fossils. 



Conus floridanus Gabb.

 Conus floridensis Sowerby. 



This species differs from the fossil C. niarylandicus Green chiefly in its 

 greater anterior attenuation and straighter sides. A number of specimens 

 which seem properly referable to it were obtained from the Caloosahatchie 

 beds. The recent form is found as far north as Cape Hatteras, but is not 

 known from south of the Florida Keys. 



Conus pygmseus Reeve. 

 Comis pygvKzus KeeMQ, Conch. Icon. Conns, fig. 260, 1843. 



Caloosahatchie beds. The recent form ranges from Florida southward to 

 New Grenada and ainong the Antilles. The fossils referred to this species 

 sometimes retain indications of their color-pattern. They are shorter, stouter, 

 more squarely and generally channeled than C. Pealii and the channels are 

 crossed by elevated lines of growth not visible elsewhere.
