Prof. Bottger considers this form distinct from U. hatavus, 

 with which I had united it. 



The collection, presented by Mr. Giiuther, although containing 

 few specimens of each species, and mostly in poor condition, 

 forms a useful addition to the Museum collection, which contains 

 but very few specimens from the north-western part of Persia. 

 Their value is also considerably enhanced by their having been 

 partly named, or their names confirmed, by Prof. Bottger. Most 

 of the species quoted are extremely common forms, having a wide 

 geographical range in the South and South-east of Europe and 

 Turkey in Asia. Their distribution is well known and fully 

 recorded in various works. Westerlund's ' Pauna der paliiarct- 

 ischen Region,' and Eossmassler's ' Iconographie der Land- und 

 Siisswasser-Mollusken, etc' should be consulted for such 

 information, references, and figures.
