PONSONBY : LAND SHELLS OF GIBRALTAR. 1 95 



28. Pupa cylindracea Da Costa, 



which we are now told is an older and better name than 

 the familiar umbilicata Dp. No doubt the former is an 

 older name, but whether it is therefore, like wine in bottle, 

 any better than it was when Jeffreys rejected it, must be 

 settled by more competent judges. 



29. Testacella ? 



There can be no question that a species of this genus in- 

 habits Gibraltar. Some two or three years ago two 

 specimens were found there by an English clergyman. 

 The shell of one of these specimens is now in the collec- 

 tion of Mr. Dautez, an indefatigable naturalist, who resides 

 at Gibraltar. The other may still be in the original 

 collector's hands. This year again a single specimen 

 turned up in damp grass interspersed with stones, but was 

 most unfortunately lost before it had been examined. Mr. 

 Dautez states that the Testacella is to be found among the 

 rocks above the Moorish Castle, and it is to be hoped that 

 some one will be able to verify this assertion before long. 

 This year also a number of Hyalinia of the Vitrea 

 group were collected, and these have been, as were the former 

 specimens, submitted to Dr. Boettger, of Frankfort. He has 

 now satisfied himself that the shell which he had before considered 

 to be H. B otter a Pfr. is really the H. enstilba Bgt., which, 

 it may be added, has also been found at Tangier, on the opposite 

 African coast. 



Additions to the ' Mollusca of Clapham.' — In look- 

 ing over my collection I find I have taken at various times the 

 following species not enumerated in Mr. Richardson's list : — 

 Helix concinna Jeff, foot of Ingleborough, Pisidtum pusillum, 

 Planorbis vortex, Physa hypnoriim, and Limncea glabra in a 

 pond on Clapham Common, and Limncea truncatula in a brook 

 near Clapham Station and on Ingleborough. — W. E. Collinge.
