Limaces are rare in Arizona, but Mr. Ashmun took specimens at, 
Nogales, Pima county, 4,000 ft. elevation, and they were found by one 
of us in Miller, Brown and Tanner Canyons in the Huachucas. 
These slugs belong to the very widely distributed group of Agrio- 
limax levis, but we have not been able to refer them directly to any 
described race. By the development of entocones on the lateral teeth 
they differ from A. campestris (including montanus Ing.), and agree 
with A. hemphalli (Binney),’ A. stenurus (Strebel)® and A. berendti 
(Strebel).? Whether these forms are specifically distinct or not 
remains to be determined. Their distinctive characters do not seem 
important. 
The alcoholic specimens from Miller Canyon have the general aspect 
externally of A. campestris. The rounded back is black, flanks sooty 
brown. The mantle is large, and more than half of it is free, so that 
when lifted and turned back it more than covers the posterior adnate 
portion. Under it the surface is yellowish. ‘The sole is very narrow, 
conspicuously tripartite. The central tooth is tricuspid. Laterals 
have a small entocone elevated on the side of the mesocone; ectocone
