ANOMA. 23 



Aboukir, in southwestern St. Ann (P. W. Jarvis). 



13. A. SPLENDENS (' Menke ' Pfr.). 



Shell fusiform, widest near the middle, smooth and glossy, 

 with some excessively fine strife behind the lip only; whorls 

 but slightly convex; basal keel short, blunt and strong, very 

 weak except just behind the lip. Aperture oblique, long, the 

 outer lip sinuous, columellar lip angular and notched near the 

 insertion. Columella truncate, though sometimes not veiy 

 noticably so from the aperture. Axis distinctly sinuous in 

 the penult, whorl, thickened by a subspiral callous in the last 

 whorl (pi. 12, fig. 57). 



Central Jamaica: Manchester. 



A group of middle Jamaican varieties, very closely related 

 to the A. lev-is series, but without dark bands on the last 

 whorl, smoother, with shorter basal keel and more twisted axis. 



The identity of Wood's original Helix maugeri (pi. 18, fig. 

 24) probably cannot now be positively settled. It is a matter 

 of conjecture. The figure suggests A. nigrescens rufilabris 

 somewhat, but the correspondence is not sufficiently close to 

 be conclusive. It was originally introduced by Wood in the 

 Supplement to the second edition of his Index Testaceologicus, 

 p. 22, pi. 7, f. 31 (1828), without description, with the habitat 

 West Indies, and a sign indicating the length as three-quarters 

 of an inch. Sowerby (1834) figured as maugeri a form dif- 

 fering from that of Wood, and referable to A. nigrescens 

 quadricolor. Pfeiffer (1848) gave the first description of 

 maugeri, which, while it covered several forms, applied par- 

 ticularly to tricolor, citrina and albida of C. B. Adams; but 

 earlier (1841) the names splcndens and hornbeckii had been 

 proposed for the first of these, and none of the three agrees 

 very closely with Wood's figure. Regret as we may the 

 change of a well-known name, it is the better course to delete 

 maugeri as not identifiable.
