484 MR. E. A. SMITH ON NEW SHELLS. [Juue 15, 



granules is finely, irregularly, and somewhat obliquely striated ; and 

 the base exhibits intermediate concentric striis between the rows of 

 granules. The carina, visible upon the body-whorl, winds up the 

 spire just above the sutural line, and upon the upper whorls espe- 

 cially is furnished with numerous, somewhat tubulous short spines, 

 which, lying upon the volution beneath, give to the sutural line a 

 festooned appearance. No locality, unfortunately, is attached to 

 this shell, but it is probable that it is a Chinese or Japanese form.

This is a remarkably sculptured shell and very peculiar in form. 

 The upper whorls and half the last one are flattened at the top, and 

 scarcely slope at all. The last half of the body-whorl, however, 

 upon which the plicae become very much larger than those above, 

 is a little convex. The lines of growth are elevated, excessively 

 close together, and cover the entire surface of the shell, being con- 

 tinuous upon the keels and lirae and in the interstices between 

 them. The plicae are somewhat acuminately produced upon the 

 upper carina, which, when viewed from above, presents a prettily 

 festooned appearance. The immense thickening at the base of the 

 body-whorl is very remarkable, and forms an excessively thick base 

 to the aperture. Between this thickening and the lower keel the 

 whorl is a little constricted or concave, especially so towards the 

 mouth ; and in this part the transverse liras, about twelve in number, 

 are finely granulose. The plicae do not extend below the keels, nor 

 do they interrupt the spiral lirae, the latter being continuous on and 

 between them.
