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 Icevis, 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. hemphilli (Binney), 7 A. stenurus (Strebel) 8 and A. berendti 

 (Strebel). 9 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
