34 THE NAUTILUS. 
Every day I carry with me, a smail tin box, one which I can 
very conveniently carry in my pocket, in which my “ finds” are 
contained ; and when a morning is very damp, the result of a rain 
the day before, or when a heavy fog settles over the city, then I 
take with me a much larger box, inasmuch as I find that I can col- 
lect two or three times the amount of specimens that I would when 
the ground is not very moist. 
Some mornings I gather great quantities of Zonites lucidus 
Drap. (sent to Mr. Pilsbry to be identified) while other mornings, 
Agriolimax agrestis Linn. may be found very numerous. However, 
the following list may be called a fair sample of the specimens I 
collect, while on my daily walk. 
Specimens gathered on Nov. 11, 1893. No. collected. 
Helix (Lysinoe) nickliniana Lea var. reticulata Pfr. 48 
Zonites cellarius Mull. 3 
Zonites lucidus Drap. 32 
Ariolimax columbianus Gld. 5 
Amalia hewstoni Cooper 13 
Agriolimax agrestis Linn. 27 
Limax maximus Linn. 30 
Prophysaon andersoni Cooper 21 
Total 179 
I may add, that of the above species, although Limax maximus 
Linn., has only been an inhabitant of this country for a period of 
about two years, it has multiplied so greatly, that it has become a 
nuisance to people who have flower gardens. 
The slugs I find, generally crawl across the cement sidewalks and 
walls surrounding residences, while the Zonites apparently delight 
in crawling over the wooden door steps, and the Helix reticulata 
prefer secluded spots in vacant lots, among the grass or under 
boards, Of the last named species, I have at present, almost a 
thousand specimens and of the Zonites lucidus Drap. over three 
hundred specimens. 
Is it not worth while then, to be “ on the lookout” for specimens 
when out walking? One can thus see how I profit by my daily 
walk. ;
