VARICELLA, JAMAICA. 80 



tured like the later whorls, but more closely and finely. The 

 upper half of the aperture is very narrow. The outer lip 

 is straightened in the middle, or a trifle bent in. In profile 

 it arches forward in a broad curve, and is somewhat thick- 

 ened from the middle -down. The columella is short, and 

 very strongly truncate at the base. Length 17, diam. 5.9, 

 aperture 8.2 mm., whorls 8.

Pfeiffer's type, the figure of which is 'copied in Vol. I, 

 was a more lengthened, less robust form with shorter and less 

 narrow aperture, length 16, diam. 5, aperture 6.75 mm., with 

 8 whorls. 



There is also a variety, lengthened like typical form, in 

 which there is a drop-like callous thickening at the middle 

 of the outer lip. The sculpture is coarser, there being 'about 

 3^/2 riblets in a mm. on the last whorl. Length 14.4, diam. 

 4.9, aperture 7 mm., whorls 7 1 /o

"Perhaps a variety of A. phUlipsii, but the shell is sculp- 

 tured with close longitudinal stria?, is never banded with 

 brown ; the inf ra-sutural line is further from the suture, and 

 the spire is shorter. Divergence 22, length of spire .3, total 

 length .54 inch., width .175 inch." (Ad.}.

The type lot consists of nine specimens, one of them fig- 

 ured, pi. 9, fig. 44. There are a few very inconspicuous 

 varices marked by a light hair-line and a pale streak on the 

 pale yellowish-corneous shell. The columella is straight and 

 vertical in profile view; outer lip equably arched forward.
