48 THE NAUTILUS. 



Loc: Valley of Urmara, Talas-Alatan, Turkestan. Alt. 8500 

 feet (O. Rosen). 



A distinct form, recalling in shape Bui. Kuschakewitzi, Anc, of 

 Namangan, Khanat of Khokand, but very distinct and with the 

 peristome less developed. 



Some of the Bulimini that I have described from the same 

 countries bearing only the very vague locality, Turkestan, I now 

 avail myself of the opportunity of mentioning the precise localities of: 



Bui. Ujfalvianus, Anc, Usgent. 



Bui. Turanicus, Anc, Usgent. 



Bui. trigonochilus, Anc, Samarkand. 



Bui. Annenkowi, Anc, Margelan. 



Bui. Kuschakewitzi, Anc, Namangan. 



Bui. Bomalotianus, Anc. (emend.), Alai. A smaller, highly 

 colored variety which I propose to call var. colorata. 



Bui. intumescus is also found at Osch, Eastern Turkestan, with 

 Bui. albiplicatus, von Mart. The former appears to be a widely 

 spread species. 

 2. Buliminus albocostatus, n. sp. 



Shell small, rather thick, slender, cylindrical, turreted, rimate, 

 shining, brownish horn-color or brownish, sculptured with strong, 

 numerous, rather regular, white folds. Apex obtuse, smooth, horn- 

 colored. Spire long, regularly attenuated, subcylindrical below. 

 Whorls 8-9, somewhat convex, slowly increasing, suture simple? 

 moderately impressed ; the last whorl not much broader than the 

 preceding one, barely attenuated or narrowed towardg the base, 

 minutely ascending in front. Aperture nearly vertical, ovate, some- 

 times produced externally, angulated superiorly. Peristome white, 

 thickened, superiorly straightened, flatly expanded, margins not dis- 

 tant, joined by a heavy callosity. Columella simple, internally 

 simple, not folded, externally broad. 



Length 8^-10, diam. 3, length of apert. 2^ mill. 



Loc: Valley of Karagoin, Turkestan (O. Rosen). 



A charming and sharply defined, graceful species which I received 

 at first labeled as '' Bui. albiplicatus, von Mart., variety," and sub- 

 sequently as " Bui. albiplicatus. West." I am not aware it was ever 

 published by Wester) und. From B. albiplicatus it differs in being 

 smaller, more slender and the characters of aperture, as well as the 

 relative proportions, are altogether dissimilar.
