CALLIOSTOMA. 375 



I am indebted to Mr. C. W. Johnson of the Wagner Free Insti- 

 tute of Science, Philadelphia, for specimens. Dr. Dall says : 



This fine species varies in color from dark rose to yellowish-white, 

 sometimes unicolor, sometimes variegated with whitish clouds radiat- 

 ing from the invariably purplish apex. It is referred by Reeve to 

 Tasmania, in error. It is the commoner imperforate species of 

 Florida, often collected by tourists, and is found in the Caloosahat- 

 chie marls. I have seen no specimens from the Antilles, nor have 

 I seen it quoted by any author from the West Indies. It may 

 probably exist in Cuba.

Shell conical, much elevated ; pale claret color, with a dark brown 

 apex, and large ill-defined spots of white ; with spiral series of 

 minute dark red oblong spots, which are proportioned to the size of 

 the spiral ridges on which they are placed ; the ridges of least size 

 are not spotted ; solid, with ten or twelve minute spiral ridges, of 

 which one near the base of the whorls is larger, and three are of an 

 intermediate size, viz., one on each side of the suture and one on the 

 middle of the whorls ; on the lower side of the last whorl are 

 sixteen or eighteen other minute revolving ridges, of which every 

 second or third is spotted ; apex acute ; spire with the outlines nearly 

 rectilinear; whorls seven and one-half, a little concave, acutely 

 prominent in the lower part ; last whorl subangular, moderately 

 convex beneath ; aperture subquadrate, iridescent within ; columelJa 

 subtruncate ; umbilicus wanting. The whorls in this shell have the 

 same form as in T. jujubinus, and the general form of the shell 

 is like that of T. pyramidatus.

Shell large, strong, regularly conical, with a flattened base, no 

 umbilicus, yellowish white or light yellow, with more or less numerous 

 narrow, spiral bands of pale brown or dark brown, and with large 

 squarish spots of bright rosey red on the spire. Whorls nine or ten, 

 flattened, or concave, below the suture, which is not impressed. The 

 last whorl has eight to ten conspicuous, raised, nodulous revolving
