178 HELIX-JACOSTA. 



This pretty species belongs to the series of H. joppensis Mouss., 

 KrynicTcii Andrz., subkrynickiana Mouss. It is the smallest of the 

 group yet published. (Anc.} 



H. MILLEPUNCTATA Boettger. PL 44, figs. 70, 71, 72. 



Differs from H. bargesiana Bgt. 1854, (=joppensis A. Schm. 

 1855) in the non-excentric, more funnel-shaped umbilicus, whorls 5, 

 not 6, more rapidly increasing from the beginning, the smoother 

 sculpture, the striae being closer, less acute, more irregular, and in 

 the color. 



Shell whitish or horny-white, apex brown ; always having a nar- 

 row brown peripheral girdle ; very elegantly ornamented with 

 microscopic rounded tawny dots, either irregular or arranged in 

 numerous spiral lines, absent on the umbilical region. 



Alt. 9, greater diam. 14, lesser 12s mill. ; aperture, alt. 6}, width 

 6| mill. 



Persia: Schah-rud, in the North Persian province Irak Adschmi; 

 varieties also widely dispersed in Asia Minor and northern Syria. 



Helix (Xerophild) millepunctata BTTG., Zool. Jahrb. iv, p. 948, 

 t. 27, f. 13a-c. (1889.) 



Differs from bargesiana Bgt., which I take to be a banded form of 

 joppensis Schm., in the much more rapid increase of the inner whorls. 

 H. bargesiana, proteus Rossm. and Krynickii Kryn. are remarkable 

 for the at first extremely slow increase in width of the whorls, 

 the last one then widening very rapidly ; whilst millepunctata is 

 normal in this repect, not unlike H. derbentina Kryn. ; but from 

 this last the entirely different marking separates it. 



HELIX (XEROPHILA) SINAICA v. Martens. Sitzungs-Bericht der 

 Ges. Naturforsch. Freunde zu Berlin, nr. 10, 1889, p. 200. Djebel 

 Musa, 2000 meters alt., and Wadi Barak, Sinai. Distinguished from 

 eremophila and erkelii by the raised spire and narrower umbilicus ; 

 from joppensis and bargesiana by the less rounded whorls and nar- 

 rower umbilicus.

H. BIANGULOSA Martens. PI. 44, figs. 85, 86, 87. 



Shell umbilicated, conic-depressed, biangulate, closely radially j 

 costulate-striate, white, variegated with pale brown ; spire graduate, 

 apex obtuse. Whorls 41, the first pale brown, unicolored, smooth, 

 the following obtusely angulated and banded a little under the
