114 VARICELLA, CUBA. 



ing wholly obsolete. The last whorl is nearly smooth except 

 for lightly impressed varix lines, of which there are four on 

 the last, an equal number on the penult., and fewer very faint 

 ones on the earlier whorls. The outer lip is slightly arched 

 forward, and at its lower third a very small lobe or point 

 projects, hardly shown in fig. 64. This point also shows on 

 the varix-lines of the last whorl. The columella is concave 

 above, prominent and 'abruptly truncate basally. Length 

 17.4, diam. 6.9, aperture 8 mm., whorls 6%.

The shell resembles V. Iriiiilar-ia in contour. It is thin, 

 pale brown and glossy. The first 2y 2 whorls are smooth ; 

 then close, fine strife begin abruptly. This sculpture con- 

 tinues throughout the shell, the stride slowly increasing. On 

 the last whorl they are regularly arcuate, rounded, and much 

 wider than the linear intervening grooves; at the lower third 

 of the whorl they rather suddenly diminish, leaving the 

 base almost smooth. On the front of the last whorl there 

 about four stria? in the space of one mm. The varices are 

 indistinct, and about five in number on the last whorl. The 

 aperture is rhombic-ovate. Outer lip thin, well arched for- 

 ward, with a very minute point projecting at its lower third. 

 Columella nearly straight, abruptly truncate at the base. 

 Length 18, diam. 6.9, aperture 8 mm. Whorls 6%. 



Cuba (A. D. Brown coll., from T. Bland). 



This differs from the preceding form by the close, fine 

 striation of the later whorls. 



60. V. SWIFTIANA Pilsbry, n. sp. PI. 11, fig. 61. 



Shell turrite, the spire with straight outlines and obtuse 

 apex; thin, corneous or corneous-brown. Surface glossy. 

 First 21/2 whorls smooth; following whorls sculptured with 

 widely spaced, arcuate grooves extending from suture to 

 suture. The last whorl has unequal, irregularly spaced 

 grooves, subobsolete on the base, and occasional varix-lines, 

 four or five in number, each preceded by a narrow whitish 

 streak. On preceding whorls the varices are very few and
