here given shows the general positions of localities mentioned in the 
text. 
The first mollusks collected in the Huachucas were taken by a 
Mr: Cox, who sent some Helices to Dr. Isaac Lea many years ago, 
with the locality “‘Tucson.”’ These shells are what we now call Ashmun- 
ella varicifera. Nothing is known of Cox beyond his name on the 
label. At the time these shells were collected Tucson was no doubt 
the nearest settlement or post to the Huachucas, and hence was put 
down as the locality. It is not unlikely that Cox picked up these 
shells in the course of a chase from the army post at Tucson after 
marauding Apaches. Be this as it may, Ashmuwnella varicifera is an 
indubitable Huachucan snail, and was collected at a time when hostile 
and dangerous Indians occupied that country. On the death of 
Dr. Lea the specimens came into the possession of the National Museum, 
where they are now preserved. 
In 1880 Mr. Bland described a snail, T’riodopsis levettei (now Ash- 
munella levetter), collected by Dr. G. M. Levette, and thought to be 
from near Santa Fé, New Mexico. Explorations in that region have 
shown that the Ashmunellas there are of a somewhat different type, 
and the true habitat of the species was not known until Mr. Ferriss 
rediscovered the species in the Huachucas, where it is restricted to the 
heads of certain canyons. It is certain, therefore, that Dr. Levette 
had forgotten where he procured the original specimens, which are 
now in the American Museum of Natural History, New York. 
The first snails actually reported from the Huachucas were collected 
by Dr. Edgar A. Mearns, U.S. A.,a member of the party surveying the 
Mexican boundary in 1892-1894. They were described by Dr. W. H. Dall 
in two papers,” published in 1895 and 1896. Six species were obtained 
in the Huachuca range 3

anatomical researches which led to the establishment of new genera for the 
Helices of that region. He had only dry shells to deal with, and hence followed.
