THE NAUTILUS. 1H 
lamellz in the palatal wall, yet there is hardly a doubt but that it 
represents Gould’s species. Messrs. Geo. W. & P. B. Webster took 
much pains, last fall and winter, on their trips in eastern Florida, to 
secure specimens, but so far did not succeed. Whoever visits the 
Peninsula should look after it. 
From the whole configuration and especially the lamellee, variolosa 
appears to be a Vertigo. 
Vertigo gouldii Binn. 
The true V. gouldii* has been collected at Helena, Mont., by Mr. 
I. B. Elliott, and at Ottawa, Ont., by Mr. Geo. W. Taylor; from the 
latter place in 2 somewhat differing forms. To mention it here, my 
V. callosa has not been found South of New York, nor west of 
middle Ohio, so far, to my knowledge, and among hundreds of small 
Pupidee collected in Northeastern Ohio, by Mr. A. Pettingell, there 
was no example of that species. 
Vertigo binneyana Sterki. 
When this species was first published, ? I had only 2 examples 
from Helena, Mont., and 2 from Winnipeg, Manitoba, but was 
satisfied that it is a distinct form Since then I have seen 2 from 
Glendive, Mont., and one from Albuquerque, N. Mex., the latter 
differing somewhat from the northern example, but unmistakably 
ranging with them. Thus it seems to live in the whole region of the 
western mountains. 
Vertigo bollesiana Morse. 
Specimens have been collected at Sewanee, Tenn., the most 
southern habitat on the continent I know of, by Mr. Sanderson 
Smith. But a short time ago I saw, in a number of P. servilis Gld., 
from St. Croix, W. I., one example of this species, with rather strong 
lamellae. Whether it was collected with its companions or later 
accidently mixed in, is hardly to be decided otherwise than by other 
specimens brought from the West Indies. 
The species is variable. Most examples from New York, Ohio, etc., 
are of good size, regularly striate, and of chestnut color, while those from 
New England and Canada are generally smaller, lighter in color and 
searcely striate or nearly smooth ; the inferior columellar (or “basal”’) 
lamella is sometimes quite small or even wanting. A peculiarity of
