84 VARICELLA, JAMAICA. 



is flattened and tapers slightly downwards 'below the sub- 

 sutural inflation. The suture is very narrowly channelled. 

 The outer lip is very slightly arched forward below the 

 middle, basal lip somewhat receding. The columeJlla is very 

 strongly twisted. Large examples measure, length 31, diam. 

 11.5, aperture 14.7 mm. ; whorls 9i/ 3 . 



There is some variation in sculpture. A specimen from 

 Mulgrave (figs. 26, 27) has coarser riblets than most others 

 examined. 



Jamaica: Grand Vale, a sugar estate near Kilmarnock 

 (Gosse) ; Maroontown and "Westmoreland (E. Chitty in coll. 

 C. B. Adams); Mulgrave (J. B. Henderson).

The habitat of Pfeiffer's type from the Cuming coll. was 

 unknown, but Ph. Gosse, returning from Jamaica about the 

 time of its description, brought specimens from Grand Vale. 



29a. Var. elegans (C. B. Adams). PI. 8, figs. 28, 29, 30. 



Smaller than V. pliilippiana, less swollen below the suture, 

 with the chestnut stripes narrower. The striation is de- 

 cidedly finer than in philippiana, there being five stria in a 

 mm. on the last whorl. 



Length 23.5, diam. 9, aperture 11 mm. 



Length 28.5, diam. 9.7, aperture 12.5 mm. 



Figures 28, 29 are from a specimen received from Adams, 

 and agreeing fully with his type lot at Amherst. A larger, 

 more boldly marked shell, typical in sculpture, is drawn in 

 fig. 30. This variety occurs in Manchester. 



Acliatina elegans C. B. A., Contrib. to Conch. 2, p. 25 

 (1849). 



Finely striate form. At Mandeville and Bog Walk Mr. 

 Henderson collected some remarkably handsome specimens, 

 of a tawny color, with dark but narrow chestnut stripes, and 

 more numerous striae, nearly seven in a mm. on the last 

 whorl (pi. 8, figs. 31, 32 Mandeville).
