' Rare in the Caloosahatchie beds, Dall ; living under the scales of a large 

 annelid [Acoetes htpinus Stm.) in Charleston Harbor, S. Car., Stimpson. 

 A single specimen of the typical species was found in the marls.

Newer Miocene of Duplin Co., N. Car., Burns; Post-Pliocene of S. 

 Carolina at Cainhoy, Wando River, Holmes. 



This is easily discriminated from the type by its rounder whorls and the 

 greater amount of the spire left uncovered by the advancing whorl. It is also 

 larger. Holmes, having two small species, unfortunately got his labels mixed 

 or some error occurred by which a shell {Vityinella Holmesii Dall) which has 

 no resemblance to Cochliolepis is figured as Stimpson's species, while a genu- 

 ine Cochliolepis is represented under the name of Adeorbis.

Newer Miocene of Duplin Co., N. Car., Burns ; of the Cape Fear River 

 at Mrs. Guion's marl-bed, C. W. Johnson ; living in Tampa Bay, Florida, at 

 Egmont Key, Col. E. Jewett. 



It is not improbable that further researches will reveal this species also in 

 the Caloosahatchie beds. 



Family CYCLOSTREMATID^. 

 Genus VITRINELLA C. B. Adams. 

 The place of this genus is still uncertain, and numerous incongruous 

 species have been referred to it, even by its founder. The true Viti-inellce 

 conchologically seem very like the more porcellanous forms of Cyclo- 

 strema, so that I have adopted, provisionally, the present family to include the 

 genus, as well as the more strictly holostomate types upon which it was 

 founded. 



Subgenus Episcynia Morch. 



Episcynia Morch, Mai. Blatt. xxii. p. 155, 1875 : as subgenus oi Solarium ; type 5. inornata 

 Orbigny, Moll. Cuba, p. 67, pi. xix. figs. 25-27. Recent in the Antilles. 



The type is a small hyaline, depressed shell with a single serrated carina 

 furnished with long, caducous epidermal cirrhi. 



Vitrinella (Episcynia) multicarinata Stimpson.

on the Florida coast.
