 figs. 13, 14. 



Very few specimens found. 

 " On the lower hills, Talamanca " (Gabb). 



My type specimens were obtained on the trunks of acacia trees, 

 San Jose, Costa Rica.

 ed. Nov. 30. 9, 10. 



" Dota, a high hill region south of San Jose " {Gabb). 



This species is closely allied to B. costaricensis, Pfr., but is more 

 elongated, and has a twist on the columella, with a somewhat dif- 

 ferent style of painting. 



Three specimens only.

Costa Rica. A very beautiful little, thin, globose species, pale 

 greenish yellow, ornamented with three dark-brown transverse bands 

 of oblique stripes and spots, with the lip and columella rose-colour. 



11. Bulimus zhorouinensis, n. sp. (Plate XL. fig. 4.) 



Shell somewhat broadly perforate, elongately ovate, moderately 

 solid, rather coarsely and irregularly obliquely striated, especially 

 towards the base of the last whorl, crossed here and there with 

 single or double narrow impressed lines, between which are rows of 

 numerous short descending striae ; whitish or pale brown, painted with 

 narrow, distant, longitudinal darker brown flames ; whorls 7, rather 

 convex ; spire sharply conical ; sutures impressed ; apex straw- 

 coloured ; aperture large, ovate, effuse, pale lilac-brown within ; 

 outer lip white, very much expanded, flattened and a little recurved ; 

 columella triangularly flattened and expanded over the umbilical 

 region, ending in a blunt rounded callus interiorly. 



Diam. 12, alt. 23 lin. 



Hab. " Middle Zhorquin to Cuabre, low hills and flat ground " 

 (Gabb).

 tudinal sculpture and the dark purple mouth. It is also allied to 

 B. pallidior, Sow., from " Central America ;" but that shell is
