100 VARICELLA, JAMAICA. 



marked with a narrow chestnut stripe which is interrupted 

 below the periphery, and very weak below the interruption. 

 The outer lip is thin, regularly arcuate, and below the middle 

 bears a small triangular callous pad within the edge. The 

 columella is but slightly concave, and is weakly obliquely 

 truncate 'basally. There are three embryonic whorls, the 

 last terminating 1 with a varix-line and brown stripe. The 

 half whorl preceding this varix is closely costnlate like the 

 following whorls, the earlier whorls being smooth. This 

 species is related to V. similis, but differs by the stouter con- 

 tour and much closer sculpture of the last whorl. The char- 

 acters of the early whorls separate it from V. nemorensis, 

 which is otherwise very closely related.

"Shell sub fusiform; pale brown or pale reddish brown, 

 with dark brown transverse stripes, which are not very wide, 

 reaching nearly to the anterior extremity, about four on each 

 whorl except on the first three, which have none ; with very 

 dense rather small stria 1 ; spire with the outlines quite con- 

 vex; whorls eight, moderately .convex, with a well impressed 

 suture; aperture long, narrow in the upper half, and very 

 acute above ; labrum sharp, produced along the middle, a 

 little angulated below the middle ; columella nearly straight, 

 rather slender, and pointed. Mean divergence 30 ; length 

 .83 inch; breadth .25 inch; length of aperture .35 inch. 

 'Var. a, with very few brown stripes." (Adams).

This species is very closely related to V. phillipsii, differ- 

 ing in little but the somewhat less attenuate spire and the 

 sculpture of spaced grooves on the third whorl. The shell is 

 so translucent as to show the axis faintly through. The type 

 lot consists of about 20 specimens. The first 1% or 2 whorls
