HELIX-FRUTICICOLA. 187 



3 or 4 times as narrow as their interstices, and with the convexity 

 directed backward, not toward the mouth ; between them excessively 

 fine spiral lines appear. (Ms.) 



H. PROCLIVIS Martens. PI. 46, figs. 52, 53, 54. 



Shell narrowly umbilicated, subdepressed-globose, distinctly striat- 

 ulate, corneous, the suture whitish. Whorls 5?, a little convex, the 

 last rounded, deeply descending in front. Aperture broad-lunate, 

 very oblique ; peristome white-lipped within, opaque yellow outside, 

 delicately expanded, margins subapproximating ; columellar margin 

 dilated at the insertion, partly closing the umbilicus. 



Alt. 9J, greater diam. 14, lesser 11 mill. (Mts.)

 (August, 1889.) 



The smallest specimens measured only 11 mill, diameter. Also 

 found on the mainland at Magnesia (Maltzan) and Smyrna (Boett- 

 ger), measuring 12-14 mill. The species stands between H.schu- 

 berti Roth, which is more globular, with more circular, less oblique 

 mouth, and H. grelloisi Bgt. (Amenit. ii, t. 5, f. 10-12) described 

 from the Islands of the Archipelago, but this is decidedly flatter. A 

 white sutural band is rather weakly developed by most but not all 

 of the examples before me, as well as a pale peripheral band, as in 

 so many Fruticicolas. (Mts.} , 



H. PISIFORMIS Pfr. var. ATYPA Bttg. 



Shell more shining than the type, microscopic sculpture less 

 strong, granules less distinct, last whorl ornamented with obsolete, 

 especially at the suture, spiral lines. Color sometimes whitish.

H. TRANSCASPIA Boettger. PI. 45, figs. 31, 32, 33. 



Similar to H. sericea and rubiginosa, but more allied to H. pisi- 

 formis and arpatschiana, from which it differs in the shortly hairy 

 epidermis. 



Shell narrowly umbilicated, conic-globose, subdepressed, horny- 

 yellowish or rufous brown, either with short caducous hairs arranged 

 in series forwardly descending, or yellowish, shining, very densely 

 covered with pit-like scars. Spire more or less convex-conic, apex a
