ANOMA. 3 1 



Eastern Jamaica: the east part of Portland (C. B. AJ.) ; 

 Mooretown (P. W. Jarvis). 



Cyl. m. var. sinuata C. B. A., Contrib., p. 164. 



There are in the collection of the Academy only two poor, 

 worn specimens, one of which is figured. They measure 

 17.6 x 5.4 mm. with 8 whorls, and 17 x 4.7 mm., with 8y 2 

 whorls. The mouth and lip are like pulla, but the axial 

 chink, though very narrow, is not wholly closed, and the keel 

 is less strong, though still quite strong and much longer than 

 in A. splcndcns. The " east part of Portland " of Adams' 

 time is now middle Portland, since the union with that parish 

 of St. Thomas-in-the-East, a parish which once included the 

 John Crow Mts. and coast. 



In the collection of P. W. Jarvis there are two fresh shells 

 of this species from Mooretown, Portland. They are glossy, 

 bluish-white, with a faint pink tint at the summit. The last 

 whorl becomes faintly straw-tinted, the keel and suture white. 

 Both face and back of the lip are rose-pink. 



Group of A. solida. 



Shell conic above, robust below, with well-rounded (rather 

 than tapering) last whorl, and a rather narrow, often incon- 

 spicuous, keel; back of the last whorl rib-striate. 



18. A. STRIATA (C. B. Adams). PI. 16, figs. 40-47. 



Shell rimate, obesely fusiform, thin but moderately strong ; 

 white, typically uniform, but sometimes tinted with red- 

 brown at the base. Surface somewhat glossy, finely rib- 

 striate, the stria? weaker on the upper whorl or two. AYhorls 

 somewhat convex, the last tapering, with a rather low, cord- 

 like keel below, subobsolete near the columellar lip; suture 

 strongly ascending to its termination. Aperture nearly ver- 

 tical, oval, longer than wide, the peristome thin, broad I u ex- 

 panded and reflexed, white; the outer and columellar m<ir</ins 

 level and in a plane, not sinuous, converging above, where a 

 short, thin parietal callous unites them. Colnmella seen in 

 an oblique view to be truncate below. Length 19, diam. 6.6 

 mm., whorls 7 to
