VARICELLA, CUBA. 



turrite, the apex obtuse. Whorls 6, rather flat, the last 

 about two-fifths the total length, tapering basally. Colu- 

 mella arcuate, distinctly truncate above the base of the aper- 

 ture. Aperture slightly oblique, angulate-oval; peiristome 

 simple, unexpanded, the right margin slightly dilated for- 

 ward. Length 8, diam, scarcely over 2 mm., aperture 3 x 1.5 

 mm. (Gundl.}.

'This species is closely related to Achatina pellucens and 

 costulata Ad. of Jamaica, but. differs from both in the com- 

 paratively much longer aperture and the strong truncation 

 of the columella." 



This species has not before been illustrated. It is figured 

 here from a specimen received from Thomas Bland. It is 

 pale yellowish corneous, subtranslucent and very glossy. The 

 first 21/0 whorls are smooth and glossy. The rest are sculp- 

 tured with narrow, slightly arcuate and nearly vertical 

 grooves parted by wider smooth intervals. There are about 

 41 grooves on the last whorl of the shell figured. At first 

 sight the sculpture appears quite regular, but on close ex- 

 amination occasional "varices" are seen, marked by a smooth- 

 ish streak and deeper groove. There are four of these on the 

 last whorl. The aperture is oblique, ovate, with the outer 

 lip arching forward above as usual. The columella is very 

 concave, and abruptly truncate at its base. In basal view a 

 quite narrow false umbilicus is seen (fig. 30). Length 9, 

 diam. 2.2, length of aperture 3 mm. ; whorls 63/2. 



V. data is one of the very few Cuban Oh. <n in idee which 

 show close affinities with Jamaican forms. It seems to belong 

 to the pellucens group.
