at Ronda at an elevation of 2,500 feet, and the specimens there 

 found are much flatter, thinner and of a lighter colour than those at 

 Gibraltar. All specimens at Gibraltar are most beautifully marked 

 and several well differentiated forms occur, the two most distinct of 

 which are, one with five distinct bands, three above and two below 

 the periphery, and one in which there is the usual mottling above with 

 two distinct bands below. I also took two specimens of the form I 

 have named var. A, one of which curiously enough was found 

 among the albino H. lactea. 



Helix hospitans (Bonelli). — I found a few nicely marked speci- 

 mens of this species in the ruined Roman Amphitheatre at Cagliari, 

 Sardinia. 



Var. alba. — About. equal in numbers with the type at the same 

 place. 



H. virgata (Da Costa). — Found at Gibraltar, Algerciras and Linea 

 only. Linea, I might mention, is the Spanish town which lies just 

 beyond the neutral ground to the north of Gibraltar. The specimens 

 vary enormously in size and coloration, but. for the most part although 

 the size is approximately that of those found in Great Britain their 

 brilliancy and beauty is far beyond anything I have ever seen in our 

 Islands. At Gibraltar and Linea this species is. only fairly common, 

 but at Algerciras it swarms everywhere, and exposes itself even more 

 than H, piscina and II lactea to the rays of the sun. The varieties of 

 this species most commonly met with were: — 



Var. radiata. — This beautifully marked variety is very common 

 both at Gibraltar and on the Spanish mainland and specimens 

 of it are often of great size. 



Var. albicans. — This variety is only found on the banks border- 

 ing the road which runs from Algerciras to Tarifa; it is there fairly 

 plentiful. 



Var. leucozona. — This is common at Algerciras ; the specimens 

 are usually small. 



Var. nigrescens. — Very plentiful at Algerciras, but of rather 

 small dimensions. 



Var. major.— Many specimens approach this variety from their 

 exceptional dimensions. 



H. illibata Parr. — Three specimens of this species were taken 

 near Algerciras and, so far as I know, it has not been taken there before. 

 H. caperata (Montagu). — I have taken a few specimens of this 

 species at Gibraltar, on the road running to Willis's, above the Moorish 

 Tower. The specimens are of normal size. This is I believe a new 

 record for Gibraltar. I also took a few specimens, of this species on 

 the top of the hill where the monument to the officers and men of
