86 VARICELLA, HAITI. 



neanic stage begins with occasional red-brown streaks. There 

 are a few very inconspicuous varices on the later whorls 

 (3 on the last). The surface is marked with impressed spiral 

 lines. The suture is channelled more conspicuously than in 

 V. procem, and the internal axis is very sinuous.

Although credited to Peru, this species may turn out to 

 be from Haiti or possibly Jamaica. It was one of the Dom- 

 bey shells described by Lamarck, and still remains an ex- 

 tremely rare species. It is known to me by an imperfect 

 example in coll. A. N. S. P.

A rather thin shell with sculpture of close longitudinal 

 folds, 'obsolete below the middle, and having close spiral 

 lines throughout. It has angular irregular streaks of chest- 

 nut, and brown spots. The outer lip is somewhat arcuate. 

 Length 28, diam. 11 mm., whorls 7. 



Barahona, Santo Domingo (Salle). Cf. Crosse. Journ. de 

 Gonchyl. 1891, p. 102, who places the species in Streptostyla. 

 I have not seen specimens. 



Section VARICELLIDEA Pilsbry, n. sect. 



Large forms with rough, coarsely reticulate sculpture of 

 vertical folds and spiral grooves, the varices and outer lip 

 almost straight in profile view ; spire long ; columella abruptly 

 truncate at the base. Characters of the embryonic whorls 

 unknown. Type V. texta. 



The shells of this Haitian group have sculpture somewhat 

 like a loosely woven fabric, reminding one of the Urocoptid 

 group Archegocoptis. It is related, by its spiral sculpture 

 and straight lip and varices to Varicellopsis. Two species 

 are known, both very rare, V. fulminea being still unique, 

 almost a century since its description.
