240 HELIX. 



Var. EUPHRATICA Martens. PL 67, fig. 97. 



Thick, heavy ; bands sharply defined on a white ground ; growth 

 striae sparse ; peristome with a thin reddish-brown callus, coluraellar 

 margin clear brown ; umbilicus wholly closed. 



Diam. 50, alt. 44 mill. (Kobelt.) 



Mesopotamia. 



Fig. 97, pi. 67, is a copy of Kobelt's figure ; fig. 39, pi. 63 is 

 said by Boettger to represent this form, but it seems to partake 

 fully as much of the characters of var. castanea. 



Var. RUMELICA Mousson. PL 67, fig. 94. 



Allied, by the preponderance of the spire and the smallness of the 

 aperture, to H. onixiomicra, which is, indeed only a further develop- 

 ment of this form. It resembles, also perhaps, the var. rumelica as 

 characterized by Mousson, but the umbilicus is remarkably widely 

 open, exhibiting the second whorl within. The color is very intense ; 

 the umbilical tract flecked with brown, the fifth band, usually the 

 most prominently defined, is broken into spots. (Kobelt.) 



Rumelia. 



The above description applies to the shell identified by Kobelt 

 with the var. rumelica. I am unable to say how correctly it repre- 

 sents Mousson's form. 



Var. ELONGATA Bourguignat. PL 67, fig. 96. 



More elongated than any other variety ; aperture short and very 

 oblique ; distinctly spirally striate beneath the suture. 



Central Italy. 



I follow Kobelt's identification here, as in the preceding variety. 



Var. STRAMINEA Briganti. 



Larger than the type, more elevated, the last whorl very large and 

 globose. Diam. 45-50, alt. 45-53 mill. 



Central Italy. 



Var. elongata is scarcely distinct from this form. 



Yar. ONIXIOMICRA Bourguignat. PL 59, figs. 52, 53. 



Conic, globose, narrowly perforate or covered ; whorls 6-7, regu- 

 larly gradually and more slowly increasing than in the typical lu- 

 corum; aperture small, oblique. 



Diam. 42, alt. 38 mill. 



Balkan Peninsula. 



Compare var. rumelica.
