three have been obtained in a moribund state,—a single one 
only with sufficient life to enable Gundlach to describe and 
figure the animal. A few square yards contain all we know 
of this species. Achatina fasciata is found from one end 
of the island to the other, and at all elevations above the 
sea, under several forms which have -been described as dis- 
tinct species. Helix picta Born. is another widely diffused 
shell, and extremely variable in color and size. I have ob- 
Served many young in the top branches of a high tree just 
felled, on the very. top of the mountains, in Yateras. It seems 
to be a high climber, which may account for its comparative 
Tarity, fully grown and alive. I have met with very few. 
Cylindrella. is largely represented in Cuba, more than 
eighty species being enumerated in the latest catalogue. 
Most of the species are extremely local ; several, so far as 
is now known, being restricted to localities of a few yards 
Square, or to a few rods. Doubless other localities will be 
discovered for many of them. A few, as C. Poeyana, G. 
elegans and C. irrorata, are much more widely spread, but 
probably not one extends through the whole island as does 
Achatina fasciata. But what is most noteworthy is the re- 
markable tenacity of life possessed by many species. Some 
have lived for months, and even years; and, unless. closely 
confined, they will crawl forth on the return of warm, damp 
Spells of weather, getting into the wrong boxes and creating 
Sad confusion.

ANOTHER point of interest worthy the attention of the 
observer, and furnishing subject matter for the microscope, 
is a sort of dimorphism,* and even something like alternate 
generations such as is observed in the lower animals. We
