lines long, 4 wide. Peru. (C. fy /., Catalogus, sect, ii, pt. 1, Man- 

 tissa, p. 3, 1832; Pfr., Monogr. ii, 89). According to Pfeiffer, a 

 specimen in Gruner's collection to which Ziegler had attached this 

 name agrees well with the description, and is very similar to B. nu- 

 cleus. It looks like a fossil shell. 



Bulimus versicolor Cristofori & Jan. Shell oblong, ovate, sub- 

 perforate, longitudinally striated, greenish-rufous, variegated with 

 white spots. Aperture oval; peristome reflexed, white. Length 1J 

 inches, diam. 10 lines ; aperture 1 inch long, 6 lines wide. BraziL 

 (Cristofori fy Jan, Catalogus, etc., Mantissa, p. 3, 1832); Pfr., 

 Monogr. ii, p. 47. Not Bulinus versicolor Brod., see p. 16 of vol. xi. 

 May be a Gonyostomus.

 Bulimus tenuis Anton. " = ? B. corneus Desh. Very fragile, 

 long ovate-conoidal ; 6 flat whorls, the last as long as all the rest ; 

 spire rather long ; minutely longitudinally, and still more minutely 

 transversely striated ; unicolored horn-brown, lustrous. Apex shin- 

 ing. Perforated. Aperture acutely ovate ; peristome sharp, the 

 columella dilated partly over umbilicus. Alt. 8, diam. 3J lines. 

 Similar to B. collini Mich., but slenderer, the last whorl not swollen* 

 having one whorl more, and a longer, narrower aperture " (Anton, 

 Verzeichniss der Conchyl. in der Sammlung von II. E. Anton, p. 

 42, 1839). Habitat unknown. 



Bulinus lacti color Sowerby. (Vol. xiii, PL 45, fig. 29.) Known 

 only by a dorsal view of the shell. This shows a decussated buff 

 surface, rather produced, turreted spire, and apparently a narrowly 

 expanded lip. Habitat and present location of type unknown. It 

 may be either a Lissoacme, typical Bulimulus or a Drymseus ; and 

 will probably defy certain identification. (Conch. Illustr. p. 48. 

 Bulimus lacticolor Pfr.) Ancey (J. de C. 1901) has identified with
