16a. Var. pulla (Chitty). PL 11, figs. 67, 68, 69, 70. 



Fusiform, swollen in the middle; dark brown at the ends, 

 paler in the middle, the last whorl with a slowly widening 

 creamy band below the suture. Smooth and polished, with 

 some very fine striae on the latter part of the last whorl only. 

 Keel long and very strong, its latter part creamy-white. 

 Aperture long, the lip well expanded, flesh-tinted or creamy, 

 sinuous ; columellar margin very deeply notched at the inser- 

 tion, dilated and reflexed, closely applied over the umbilical 

 chink, closing it. Columella strongly truncate in oblique 

 view. Length 15, diam. 5 mm., with 7 whorls. 



Maroon town, St. James (Chitty). 



C. m. var. pulla CHITTY, Contrib., i,.p. 9 (Oct., 1853). 



Remarkable for the closure of the axial chink by the re- 

 flexed and adnate columellar margin. Otherwise it resem- 

 bles A. paivana, except in color. 



Chitty 's type measured .68 x .22 inch (17x5.5 mm.), and 

 is thus described: " Shell small, rather slender, dark red- 

 brown, almost black at the back of peritreme. Lip cream- 

 white, and so also around the back of it, and a white line run- 

 ning along the top (below the suture) of one-half of the last 

 whorl, narrow and gradually diminishing. I have but three 

 specimens before me, not the best I imagine, and, though the 

 brown body-color is good, each seems covered with a white sub- 

 stance which scales off on application of a steel instrument, as 

 though the substance were the natural exterior. Whorls 7%, 

 with deep suture, generally shining ; with transverse striae but 

 slightly developed on the last whorl. At the top of the left 

 side of the labrum is a very deep, well-marked sinus. Aper- 

 ture very much lengthened, and keel very sharp. Length 

 .68, breadth .22 inch." 



17. A. SINUATA (C. B. Adams). PL 11, figs. 71, 72. 



: * Shell not robust and rather thin, with the lip remarkably 

 sinuate ; of a dingy pearl-white, with, on the last whorl, a fine 

 white line below the suture and another on the anterior keel. 

 Lip pale red, with a tinge of brown behind. With excessively 

 fine striae on the back of the last whorl " (C. B. Ad.).
