cart-track in Guernsey. Dr. Lukis^ who was at that 

 time and is still a resident there,, informs me that he has 

 frequently searched in vain for this remarkable shell; 

 and I have accompanied him in one of these excursions. 

 Its shape is not much unlike that of the variety tenuis of 

 H. asjjersa, which is common in Guernsey and is fre- 

 quently Landless and without coloured markings. H. 

 aperta is not found anywhere in France, except in the 

 extreme South ; it is also a native of Italy. It is the 

 H. Naticoides of Draparnaud. This snail is said to 

 fefed on vine-leaves; and it ranks with the ortolan in 

 gastronomic celebrity. Forbes^s specimen might possibly 

 have been imported and dropped by some French sailor, 

 who had feasted on its contents. This specimen, how- 

 ever, is not to be found in the British Museum, where it 

 was said to have been deposited by the discoverer ; and 

 Dr. Baird (who has the charge of this department) in- 

 forms me that he has never seen it, although he has 

 made inquiries and searched more than once for it.
