BULIMULUS-BOSTRYX-LISSOACME. 167 



Very similar to B. albatus, mainly differing in the punctiform per- 

 foration (P/V.). A variety with more or less distinct transverse 

 bands is mentioned by Pfeifter. Reeve gives an erroneous local- 

 ity. 



B. RAIMONDIANUS Pilsbry, n. n. PI. 50, fig. 40. 



Shell openly perforate, oblong-conic, solid, irregularly striate, 

 white (rarely with one or more rufous lines) ; spire turrited-conic, 

 acute^ Whorls 7, convex, separated by deep sutures, the last about 

 three-fourths the length of the spire. Columella slightly arcuate. 

 Aperture oblong-oval ; peristome simple, unexpanded, the columellar 

 margin dilated, not closing the perforation. Alt. 20*, diam. 10* 

 mill. ; aperture 10 mill, long, 5-5i wide. (Phil.). 



Between Mayoc and Huanta, Peru (Raimondi). 



Bulimus spretus PHIL., Malak. BL, xvi, 1869, p. 34. PFR., ibid., 

 p. 89 ; Novit. Conch., iii, p. 471, pi. 102, f. 11 ; Monogr., viii, p. 171. 

 Not Bulimus spretus Reeve, 1850. 



Differs from B. confusus Reeve in the smaller size, more conic 

 form, lower whorls, and less oblique sutures ; from B. turritella Orb. 

 by the solid shell. B. turritella is a species of the " caliente " region, 

 spretus of the frigid " Sierra " (Phil.). 



B. ULLO^E Philippi. PI. 50, fig. 41. 



Shell covered-perforate, oblong pyramidal, somewhat roughened 

 by longitudinal strife; white. Spire conic. Whorls 6, a little con- 

 vex, separated by moderately deep sutures, the last about equal in 

 length to the spire. Columella subvertical. Aperture patulous, 

 oblong-ovate ; peristome simple, thin, the right margin unexpanded, 

 columellar margin a little expanded, covering the perforation. Alt. 

 16*, diam. 6*-7* mill. ; aperture 8 mill, long, 4-4* wide. (Phil.). 

 " Quebrada caliente" betiveen Mayoc and Huanta, Peru. 



Bulimus ulloce PHIL., Malak. Bl., xvi, 1869, p. 34. PFR., Novit. 

 Conch., iii, p. 471, pi. 102, f. 9, 10; Monogr., viii, p. 155. 



The three specimens seen by Philippi differ a little in diameter 

 but are of the same length ; all are rugulose, destitute of epidermis, 

 with the apices roseate. In size and form they agree pretty well 

 with B. limonoicus Orb., but they lack brown longitudinal lines, the 

 whorls are neither "etroits" nor " separes par <///< .<uture pen pro- 

 fonde" the suture being quite deep. It does not agree with B. paz~ 

 ianus Orb.
