Wl)ile the writer is not a conchologist, he has for a good many 

 years been picking up such hind snails as came in his way in the 

 course of field work in other branches^ and submitting them to Dr. 

 Pilsbry for the collection at the Academy of Natural Sciences, at 

 Philadelphia. With an experience limited mainly to the eastern half 

 of Pennsylvania and southern New Jersey, where snail shells are 

 conspicuous by their scarcity and small size, his enthusiasm for con- 

 chology did not rise to a very high pitch, and it is therefore not sur- 

 prising that his first experience in a region where land snails really 

 did thrive and multiply impressed him not a little. 



The first visit to Garrett county, Maryland, was made in June, 

 1907, in company with Messrs. Bayard Long and Thomas D. Keim. 

 We stopped at the little lumber village of Jennings, as the guests of 

 Mr. Herman Behr, who was in charge of the timber operations, and 

 who gave us every possible assistance in carrying on zoological and 

 botanical collecting, and whose personal knowledge of the country 

 and its flora and fauna was invaluable. 



Jennings is located near the head of the Castleman River, a branch 

 of the Youghiogheny, which flows down into Somerset county. Pa., 

 directly north, and is bounded on the east by Meadow Mountain and 

 the west by Negro Mountain, 2000 to 3000 feet elevation, the former 

 being the watershed between the Potomac and Ohio drainage. 

 Castleman River is lined for a good part of its course with rocky 

 woodland of hemlock, sugar maple, beech, birch, oak, etc., much 

 more varied in character and witli a larger percentage of hard wood 

 than the primeval forests of the central Pennsylvania mountains. 

 These woods are often dark and damp with quantities of loose stones 

 and rocks forming their floor, partly covered by moss and low herbs, 

 but with numerous miniature caves and passages extending down 

 among them, and old moss covered tree-trunks here and there in all 

 stages of decay. During the two day? of our slay there was an almost 

 constant drizzling rain, which, however unpleasant it might have 

 been for collectors, was ideal weather for snails. They simply 

 swarmed on old stumps, logs, rocks, and even on the stems and 

 leaves of herbs and low shrubs. A modest tin box brought along
