10 Description* of Thirty Supposed Xiic Species and 



CTLINDRELLA MAUGERI, Var. UNICOLOR. AD. Yar. a. CIIITTY. 

 Near to Maroon Town, in St James, occurs what I con- 

 ceive to be a variety of this variety \ It is less shining, 

 the striae are coarser. It is less robust, and it seems less 

 liable to decollation. Out of three specimens (all I have) 

 two have apparently lost only the very apices, having 1 3f 

 whorls remaining, and the third has 1OJ- whorls left. 



CYLINDRELLA MAUGERI, Tar. BICOLOR. Shell short and 

 robust. Lip and penult whorl white, gradually growing 

 into a pure rich yellow to the truncate apex ; very shining, 

 with lines of growth only perceptible under a strong lens. 

 Whorls six. Length .6, greatest breadth .24. 



One is longer, 7i whorls. Length .64, breadth .2 1 .

CTUNDRELLA MAUGERI, Var. QUADRICOLOR. Shell thick 

 and robust Lip full rose-pink, front and back : with dark 

 brown, and black, and white marks and lines inside the 

 lip, corresponding with the external marks. Below the 

 suture of the penult whorl, on the last whorl, is a very 

 narrow spiral line of white, which is traceable, more or 

 loss, over the whole of the last whorl ; below this is a 

 broad band of black, .1 inch broad ; adjoining it, down to 

 the usual keel, but divided from the pink behind the lip 

 by the black, is a band of pure white .1 wide at its com- 

 mencement, but tapering off to nothing where it meets the 

 outer labrum : below this again, covering the umbilical 

 region, is deep black : the black band nearer to the 

 suture, when it has nearly completed the last whorl, 

 gradually shades oil into a very intense dark red brown, 

 which, in fresher shells, continues up to the truncate apex, 

 while in less fresh shells, the middle whorls assume a 

 lighter tinge of brown. Thus the shell might be said not 

 only to have four, but five colours. 



Shell shining, with close fine-set stria? at the back of 

 aperture, gradually widening and disappearing as the apex 

 is approached. Lip broad, thick, and well-reflected. Whorls
