76 VARICELLA, JAMAICA. 



resembles A. blandiana. Its divergence in the upper whorls 

 is less than in that shell, but its mean divergence is greater. 

 Mean divergence about 18; length .385 inch; breadth .095 

 inch; length of aperture .11 inch." (Adams).

The figures represent the best specimen of Adams' type 

 lot, measuring, length 12, diam. 3, aperture 3.6 mm., whorls 

 8. There are four red-brown streaks on the last whorl, the 

 next to the last one accompanying a distinct varix, the base 

 of which shows in the figure. The first half whorl is smooth ; 

 following whorl with narrow radial grooves not reaching the 

 suture below, and parted by flat intervals ; the next whorl is 

 vertically striate, and the rest ribbed; the riblets are parted 

 by intervals of twice their own width. On the last whorl 

 there are 7 riblets in one mm. The aperture is subvertical, 

 the outer lip a little expanded, blunt, equably arched for- 

 ward in the middle ; basal lip somewhat retracted and broadly 

 rounded. Parietal callus moderately developed. This species 

 is readily separable from the related V. Uandiana by the 

 wider intercostal spaces and more attenuate spire, the dia- 

 meter at the second or third whorl being decidedly greater 

 in Uandiana.

"Shell ovate fusiform, much elongated: subtransparent, 

 pale brownish yellow, with brown transverse stripes, which are 

 very narrow except at their summits, where they are much 

 dilated and are very deeply colored ; there are on each whorl 

 four or five of these stripes except near the apex : varicose 

 coincidently with the brown stripes ; with rather fine regular 

 transverse striae : apex rather obtuse, with rather more than 

 one whorl smooth : spire rather long, with the outlines a 

 little curvilinear: whorls eight, moderately convex, with a 

 well impressed suture: aperture rather long ovate, narrow 

 and very acute above : labrum sharp and thin : columella
