Guppy of the Jamaica Miocene, which is not sulcata. It is figured in the prop- 

 er proportional relation to the figure of R. floridana, which is 2.5 x 1.5 mm. 

 with five whorls. It may prove a dwarf race of R. floridana, but I have not 

 found a connecting series so far. The present form has one whorl less than 

 R. floridana, notwithstanding which the nucleus is larger in R. Guppyi. The 

 latter is more abundant and so far has not been found recent. The species 

 described by Conrad and Lea are all larger than the Pliocene fossils.

This form is intimately related to Tornatina recta Orb., from which it differs 

 only in its larger size, stouter form and slightly more elevated spire. It is 

 somewhat intermediate between T. hUlata Kiener and T. recta. The two lat- 

 ter species are recent in the Antillean region and T. recta has been found living 

 on the Floridian coast. I have examined Lea's type-specimen, which is said 

 to have come from a bed of Older Pliocene age. 



I can hardly doubt that this shell is identical with T. recta Gabb (as of 

 Orbigny), which is the same as Guppy's species. It is common to the Miocene 

 of St. Domingo, Trinidad and Jamaica. T. canalicnlata Say, non Orbigny, is 

 distinguished by its more depressed spire, more pronounced anti-sutural chan- 

 nel and more rectangular profile.

Miocene of Bowden, Jamaica, W. I.; Pliocene of the Caloosahatchie River, 

 Myakka River, Shell Creek and Alligator Creek, Florida; Post-Pliocene of 

 Simmons' Bluff, South Carolina; North Creek and other localities in Florida; 

 recent on the Atlantic Coast from Cape Cod to the Florida Keys and Gulf of 

 Mexico. 



This species is very widespread and variable both in the recent and the 

 fossil state.
