120 STROPIIOCHEILUS. 



I am indebted to Mr. L. P. Gratacap, of the American Museum, 

 for the opportunity of describing and illustrating this species. 



Subgenus Bonus Albers, 1850.

S. MAXIMUS (Sowb.). Vol. x, p. 15. 



Mousson reports specimens 140 and 160 mill, long, locality not 

 given. Possibly they were popelairianus, which is very closely 

 allied, if really distinct. (Mai. Bl. 1873, p. 4.) 



S. YPORANGANUS v. Iher. & Pils., n. sp. PL 19, figs. 56, 57. 



Shell almost imperforate, long-ovate, solid, chocolate-brown, paler 

 behind the lip, and with yellow band bordering the white-edged 

 suture below ; sculptured with rather coarse wrinkles of growth, and 

 densely finely granulose in spiral series throughout. Whorls 5^, the 

 first smooth, planorboid, two following granulose and crossed by very 

 strongly elevated, narrow and wide-spaced ribs. Post-nepionic whorls 

 exactly 2, the last half-turn of the suture somewhat oblique to the 

 preceding. Aperture slightly oblique, blue with a pearly luster in- 

 side, not much exceeding half the length of the shell, acutely ovate; 

 peristome deep rose-color, thickened, very narrowly expanded ; colu- 

 mella concave, with a slight fold above ; the reflexed columellar lip 

 and the parietal callus rose-colored. Length 91, diam. 48, longest 

 axis of aperture 50 mill. 



Brazil: Yporanga, . Prov. Sao Paulo (type no. 65. coll. Museu 

 Paulista). 



In the form and the color of the aperture it is much like S. granu- 

 losus, but S. yporanganus is more coarsely granulose, with shorter 

 mouth and diverse sculpture of the nepionic shell, the riblets in 

 gramdosus being comparatively fine, close and short. 



S. BRONNI (Pfr.), var. PERGRANULATUS nov. 



See Vol. x, p. 28. A specimen from Piquete, Sao Paulo, sent by 

 Dr. von Ihering, is densely granulose to the lip, the folds of the spire 

 are perceptibly coarser than in bronni, the penultimate whorl is 

 larger, and the last half-turn of the suture is scarcely more oblique
