KOBELT : ON THE LAND SHELLS OF GIBRALTAR. 3 



nor in Marocco. It is the same CydosfomcE ditid Fo7?iatias which 

 are wanting on both sides of the Straits (only near Tetuan I 

 found, strange to say, our Cyclostoma elegans). I further failed 

 to discover Helix vermiculata, H. variabilis, H. piofuga, H. 

 pyramidata, H. aperta, Clausilia bidejis, Bnlimus pupa and many 

 others common in other localities. 



I collected the following specimens : — 



1. Parmacella calyculata Sowerby? 



Only a few specimens under stones on the crest 

 of the rock. This species deviates considerably as 

 regards color from Deshayesii Moq. of Oran. Unfor- 

 tunately the only living specimen I collected died 

 before I was able to write a more accurate description 

 of it. The Liinax differs from the P. dojsalis Mousson 

 (Icon., fig. 1 3 1 8), to which I might refer those specimens 

 collected by me at Tangier by its considerably smaller 

 embryonic shell and thickness, by its flatter shape and 

 greater width. The dimensions are: long 17, lat. 12 

 mill. F. Deshayesii has in smaller specimens never- 

 theless larger embryonic whorls. A Liinax collected by 

 Rossmassler in 1853 between Malaga and Velez 

 Malaga, agrees in its embryonic whorls with the one of 

 Gibraltar, it is however narrower and more solid. 



2. Hyalina Draparnaldi Beck. var. 



Not very rare, especially in the churchyard among 

 the ivy covering the old town wall; in all probability it 

 may also be found in other damp places. The' above 

 reminds me at first of var. Blauneri Shuttl., and has 

 like it narrower whorls than the type and six of them 

 altogether, the stripes however are less distinct and 

 the last whorl is not quite so compressed. 



3. Hyalina calpica n. sp. 



Testa mediocriter sed pervie umbilicata, depressa, 

 superne sub lente tantum, interne vix striatula, tenuis.
