14 ANOMA. 



Western Jamaica: Northern St. Elizabeth, at Accornpong, 

 near the Trelawny and St. James boundaries (C. B. Ad.) ; 

 Ipswich (J. B. Henderson, P. W. Jarvis). St. James, at 

 Hanna Rock (P. W. Jarvis). 



I have given Adams' description above. The shell is some- 

 what smaller and usually more slender than tesselata. Some 

 specimens before me are striped with corneous-brown on a 

 gray-white ground, the stripes usually sparse or wanting on 

 the last whorl or two. A narrow corneous-brown band or line 

 runs above the suture of the last 3 to 5 whorls, and on the left 

 side of the last w r horl it continues just above, then runs upon 

 the basal keel, but does not reach the lip, behind which the 

 dark stripes of tesselata, tricolor, etc., appear. The keel is 

 not very strong, but is long, as in tesselata. The sculpture 

 does not differ much from tesselata. Specimens measure: 

 19x5.3 mm., with S 1 /^ whorls (Ipswich) ; 19.5x5 mm., with 

 91/0 whorls ; 19.5 x 5.5 mm., with 8y 2 whorls ; 16 x 5.3 mm., 

 with 7~y 2 whorls, the last being quite a stout form, with the 

 aperture very dark brown within. 



Specimens from Hanna Rock differ from the above in hav- 

 ing the sutural line blackish-brown, and obsolete, or nearly so, 

 at the periphery and keel of the last whorl. The lip is cream- 

 colored on face and back, the columellar margin is conspic- 

 uously notched at the insertion, and the throat is chestnut- 

 colored.

' Shell medium size and form, shining, yellowish, trun- 

 cated; 8 whorls left, the uppermost of which is of a light, rich 

 brown; at the back of the right lip a narrow band of rich 

 brown ; over the keel, which is white, is a shading off baud for 

 one-half the whorl of similar brown; over the umbilical region 

 the same coloring. Very obsolete lines of growth, except on 

 the last whorl, where the strige are closely and strongly set. 

 Length .77, breadth .21 " [19.2x5.2 mm.] (Chitty}.
