120 VARICELLA, PORTO RICO, HAITI. 



Spire long, the apex obtuse; whorls 7 to 8, rather flattened, 

 the last scarcely one-third of the total length ; suture nearly 

 simple, rather deep. Aperture semioval, peristome simple, 

 acute, the right margin arcuate; columella strongly arcuate, 

 truncate at the base. Length 13, diam. 3, aperture 3x2 mm. 

 (Shuttlew.).

The specimen figured is from Rio Blanco. It is a little 

 less slender than Shuttleworth's type. There are 2y 2 smooth 

 embryonic whorls, the rest with irregularly spaced grooves, 

 and occasional variees, three or four on the last whorl. 

 Length 11.5, diam. 3, aperture 3.6 mm., whorls 7. 



In the island of Haiti, tere~brccformis has been reported 

 from the Sierra Monte Cristi, in Santo Domingo (Hjalmar- 

 son, Malak. Blatter v, 1858, p. 153). I have before me speci- 

 mens from Cape Haitian, at the western extreme, collected by 

 J. B. Henderson, Jr., which may be described as follows. 

 The shell (pi. 19, fig. 34) is slender and elongate, thin, yellow 

 with an olive tint, and some very faintly darker brownish 

 streaks. The surface is glossy; suture with a dark margin 

 by transparence. The pupiform embryonic shell consists of 

 21/0 smooth whorls, the apex obtuse. Subsequent whorls 

 have widely and somewhat unequally spaced grooves, which 

 are arcuate or a little sinuous. On the last whorl about 15 

 such grooves may be counted, 5 or 6 of them being varix- 

 grooves. The latter extend to the base, while the inter- 

 variceal grooves fade out at the lower third. The aperture 

 is piriform, its length 'contained three times in that of the 

 shell. The outer lip is thin, strongly arched forward, but 

 with no trace of a projecting point such as occurs in V. den- 

 ticulata, etc. The columella is very concave, without notice- 

 able callus, and is abruptly truncate at the base. Length 

 9, diam. 2.8, length of aperture 3 mm. Whorls 6y 2 .
