174 SALASIELLA. 



seum is copied. He records the species from Turabares, 

 southwestern Costa Rica, taken by Biolley. I proposed the 

 name 8. pfeifferi as a substitute for Achatina pulchella Pfr. 

 not Spix, but on further investigation I find that Pfeiffer 

 first described the species as an Oleacina, and hence the name 

 was not preoccupied. 



7. ^. SUBCYLINDRICA Pilsbry. Fig. 1, page 171. 



Shell distinctly cylindric, the rather long spire tapering to 

 an obtuse apex ; corneous- white ; smooth except for a few im- 

 pressed lines following the direction of growth-lines. Whorls 

 4%, slightly convex, the last flattened peripherally. Suture 

 margined by transparence. Aperture of the usual shape ; 

 outer lip strongly arched forward in the middle, retracted 

 above -and below. Columella as in other species of the genus. 

 Length 5.6, diam. 1.8, length of aperture 3.15 mm.

Salasiella subcylindrica PILS., Proc. A. N. S. Phila. 1903, 

 p. 774, fig. 1. 



This species is larger and more cylindric than S. modesta, 

 and the columella is less concave. Its contour is quite un- 

 like that of S. perpusilla, which also occurred at Diente. 



8. S. ELEGANS v. Martens. PI. 28, figs. 58, 59. 



Shell long-turrite, slightly striatulate, not at all granu- 

 lose, very glossy, uniform corneous. Spire obtusely convex. 

 Whorls 8, a little convex, separated by a moderately impressed 

 suture, the last slowly tapering below. Aperture slightly ob- 

 lique, irregularly lanceolate ; peristome thickened throughout, 

 white, the outer lip convexly produced above, receding be- 

 low; basal margin rounded; columellar margin much thick- 

 ened, deeply enrarginate, as in Glandina excavata Marts., 

 broadly obliquely truncate at the base. Length 11.5, diam. 

 3.5, aperture 4 mm. (Martens). 



Southwestern Mexico: Oolima (Rolle).
