Clavella (Fusus ?) Penrose!, n. sp. PI. XI, fig. 1. 



Shell large, turbinate, with a greatly elongated canal ; whorls 

 scalariform, depressed, broadly flattened and slightly hollowed on 

 the shoulder ; no revolving lines, but wrinkles of growth faintly in- 

 dicated ; beak nearly (or fully?) the length of the spire, and twisted 

 at about its middle somewhat as in Fulgur ; canal narrow, tortuous 

 in its upper half 



Length of full-grown specimen probably 8-10 inches. 



Station 2, Rio Grande. Fragments of two specimens. The spe- 

 cies is manifestly of the type to which Fusus longcevus, of Brander 

 (Sowerby), belongs, although in that species the canal and colu- 

 mella are neai'ly straight ; to the same type also belongs Clavella 

 humerosa, of Conrad, from the Alabama Eocene. I cannot tell from 

 my specimens whether a posterior canal is present or not, but the 

 general similarity of the shell to the forms first referred to, in which 

 such a canal is present, leads me to infer that it also exists in this 

 species. 



The species differs from Fusus longcev^is, apart from the character 

 presented by the columellar arcuation, in the broader and more de- 

 pressed whorls, and in the very considerable inferior flattening of 

 the body-whorl. I have compared it with Sowerby's type (Mineral 

 Conchology, 1, p. 141, table LXIII), which is contained in the col- 

 lections of the Academy. 



Named after Dr. R. A. F. Penrose, Jr., to whom I owe most of 

 the material which has been submitted to me for examination. 

 Buccitriton scalatum, n. sp. PI. XI, fig. 5. 



Shell small but robust ; spire of about seven volutions, prominent- 

 ly turreted or scalariform ; whorls only feebly convex, flattened on 

 the shoulder and carrying a considerable number of sharp, diagon- 

 ally directed ribs, which become obsolete on the body-whorl ; revolv- 

 ing lines well-defined on the base of the body-whorl, elsewhere al- 

 most obsolete ; the flat shoulders with two impressed lines, the upper 

 of which is the most prominent. Aperture bucciniform (or colum- 

 bellseform), about one-half the length of shell ; outer lip thickened 

 near the border. 



Length, one-half inch. 



Smithville, Bastrop Co. 



This species differs from the Buccitriton sagena, of Conrad, in its 

 high and flat shoulder, in the less prominence of the revolving lines, 

 and in the obliteration of the longitudial folds on the body-whorl.
