Some Notes on American Land Shells. 39 



times, numerous specimens, at every stage of growth, of a large Ario- 

 limax, found at Santa Cruz, California, hy Miss Laura J. F. Hecox. 

 The class in the University dissected numerous individuals, working 

 out the genitalia in detail. The most casual examination showed that 

 these organs did not agree with an}- of Mr. Binney's figures, from dis- 

 sections of various west coast species, and Mr. Binney, after a careful 

 examination of the specimens, at different ages, with a stud}^ of the 

 genitalia, unhesitatingly pronounces it a new species. For the present, 

 however, I prefer to give it onl^^ the variety name above assigned, un- 

 til I have the opportunity of making a careful study of undoubted 

 specimens of A. coliimbiana, and a systematic comparison of these 

 parts. It ma}' be the form referred to by Dr. Cooper as possibly new, 

 in his review of Mr. Binnej^'s Terrestiial IfoUusks, vol. v., Froc. 

 Phil. Soc, 1879. 



Associated with it is a small, brown, slender species of Prophysaon, 

 which I have not been able to identifj- from alcoholic examples. 

 Living specimens of this Ariolimax may be seen in the Aquarium 

 and Museum of Natural History, at the Exposition Building, one 

 of which, an adult, measures fully nine inches in length, when extended. 



H. [Aglaja) fidelis, Gray.: — I have received from Washington Ter- 

 ritor}^, a very large and fine variet}^ of this species, which is entirely 

 white, save a duskj^ area around the umbilical region. In ever}'^ other 

 particular, it accords with the magnificent typical specimens found 

 there. As I had noticed upon living examples of this species, and of 

 the H. infumata, particles of pitch or resin adhering to the shells, I 

 naturall}^ concluded that these mollusks inhabited the pine trees. In 

 answer to my inquiry as to the station and habit, m^^ friend replies: 

 ^^ H. fidelis is a tree-climber, ascending the trees to a height of 30 or 

 •40 feet. We capture them in Maj^ and June when the}^ are depositing 

 their eggs in the damp moss at the roots of trees and other favorable 

 places." As neither Mr. Binney nor Mr. Bland had seen the albino 

 variet}' of this shell, until J sent it to them, and as it may be new to 

 other collectors, I put it upon record in this manner. 



H. (Zonites) rugeli^ W. G. Binney. — Mr. Binney has recently de- 

 scribed this species from specimens collected on Roan mountain, 

 Mitchell count}^, N. C, see Annals iV. I^. Acad. Sci.,\o\. i., No. 11. 

 Having received tj^pes of the species, both from Mr. Binney and from 

 Mr. Bland, I wish to put upon record its occurrence in the Ocoee Dis- 

 trict of southeastern Tenn., between Cleveland, Tenn., and the Duck- 

 town copper mines, where I collected it in July, 1878, referring it to 

 the globular variety of H. inornata, figured by Mr. Binney in Terres-
