I have a scries of eig'ht shells before me, having the shape and size of this species, 

 and differing only in color pattern. Seven of the series show more or less traces of 

 color. In two of them the marks are slightly confused, although they are rather 

 closely placed and distinctly spiral ; but the other fonr have dark spots with well- 

 defined margins and arrayed in regular revolving rows. These rows are about seven 

 in inimber although one specimen shows but five, while another eight.

I refer this species doubtfully to the Italian form on the strength of a single 

 specimen. My shell seems to have all of the characters of form as figured by both 

 the above authors, except a slightly higher spire. In colors, it agrees with Homes' 

 figure in the arrangement of the elongated spots on, and above the angle, but those 

 on the sides of the whorl are much more numerous and smaller.

I have 847 specimens of this one species, and in only two of the entire series, have I 

 been able to detect the faintest trace of color. In both cases it consists of broad, 

 badly defined longitudinal bands of dark color more or less broken. 



C. f u r V o i d e s . Gabb, n. s. 



Shell elongately turbinated, narrow, nearly or quite smooth, striated in some cases anteriorly by a few wavy 

 lines ; spire acuminate but not very elevated ; the first whorls elevated and sloi)ing on the top, acute-angulated ; the 

 later whorls more or less deeply channeled and sometimes striated on top. Aperture linear. Color pattern unknown. 



Al)out the size of C. furvus, Rve., and similar in the form of the l)ody whorl. The 

 spire, however, is much lower and the tops of whorls are markedly grooved in all the 

 specimens I have seen. An unusually Ijroad specimen before me is not unlike a very 

 narrow example of C. onouilis, which it also reseml)les in the concave sides of its spire. 



G. s t r o m b i f o r m i s . Gabb, n. s. 



Shell large, rather thin, turbinated, spire elevated, convex ; whoi'ls numerous, rounded on the angle, rudely nodose 

 and sloping to the suture, which is sharply cut but irregular. Body whoi-1 curved above, pretty regularly tapering in 

 advance. Surface marked by a few distant revolving ribs, which are most prominent, and most closely placed at the 

 anterior end. Aperture moderate, outer lip broadly, but not deeply, emarginate posteriorly. Length 2.0 inches 

 width 1.5 inch. 



In general appearance this shell is not unlike an incomplete Stromhus, but on close 

 examination it pro^^es to be a true Cone. Its blunt rounded spire and the imperfect 

 tuberculation especially of the upper whorls separate it not only from the fossil cones 

 of Santo Domingo, but from all the species of the genus, with which I am ac- 

 quainted. '

Shell turbinated, ai)ex acuminate, spire varying from nearly flat to elevated ; the angle of the elevated apical
