THE HELICOID LAND SHELLS OF ASIA. 

 CORRECTIONS AND ADDITIONS. 



By G. K. GUDE, F.Z.S, 



Thanks chiefly to the careful and painstaking scrutiny to which Mr. 

 Ponsonhy has subjected my lists of the HeUcoid Land Shells of Asia in the 

 two previous volumes of this Journal, a number of slips and inaccuracies 

 have come to light, and I have thought it useful to tabulate these. Several 

 new species have in the meantime been published, a list of which is appended. 

 From Mr. H. Rolle, of Berlin, I have lately received, with some other 

 Turkestan shells, two species which appear never to have been described, 

 and although he informs me he thinks they were published some years ago 

 in the " Nachrichtsblatt der Deutschen Malakozoologischen Gesellschaft."' 

 as I have been unable to trace them in this publication, I append 

 diagnoses. 



Cathaiea (Eueathaica) sturanyi, Koiie, n. sp. 



Shell umbilicate, depressed-conoid, opaque, pale corneous above, pearly 

 below, slightly fuscously streaked ; tinely striated, decussated with excessively 

 fine spiral lines. Spire depressed, apex obtuse but rather prominent, sutures 

 deep. Whorls 5, con\ex, rounded at the perij)hery. Last whorl not de- 

 cending in front, slightly dilated at the mouth. Aperture oblique, subcircu- 

 lar : margins convergent, united by a thin callus on the parietal wall. 

 Peristome whitish, scarcely thickened ; upper and outer margins straight, 

 basal margin slightly reflected, columellar margin slightly dilated, but not 

 impinging upon the wide umbilicus which distinctly shows half the penulti- 

 mate whorl. 



Diam. maj. 19.5, min. 17; alt. 11 millim. 



Hah. — ^Osh. Prov. Ferghana, Western Turkestan. 



Three specimens. Type in my collection. 



The new species resembles in shape C. luiddendortji, Gerstf., but that shell 

 is thinner, translucent, more depressed, possesses one more whorl, and has 

 sometimes a peripheral band, while the aperture is less rounded, and the 

 lower margin is more reflected and straight. It is also more distinctly striated 

 and strongly sculptured spirally. 



Cathaiea (Campyloeathaiea) hepmanni, Mlldff., n. sp. 



Shell narrowly umbilicatetl, conoid, pale fulvous above, whitish at the side 

 and below, finely irregularly ribbed, decussated b_\- microscopic sjMral lines, 

 which are more distinct near the aperture. Spire ele\ated, apex obtuse, suture 

 impressed. Whorls 5 — 5^, rounded, tumid below, last whorl slightly de-
