Kciv Species of Land Snail froin Califoruiu. 



in his collection; sj^ecimens are also contained in the tyijical 

 collection of my friends Binncv and Bland, and in my own 

 museum. 



Most authors would regard the above as a distinct and well- 

 marked species ; I regard it (as well as H. Hillebrandi. of K^ew- 

 comb) as a varietal form of Heli-.r Mormonum, to which it is a 

 near neighbor, inhabiting the same region. 



Binney, in his last volume on The Terr est vial Air-lireailiimj 

 MoUnsls of the United States, c(-r., in referring to if. Morinumiin 

 (on page 367), remarks : " The specimens lately received from 

 California * * * are singularly granulated on the first one 

 and a half apical whorls, and the epidermis of the next two or 

 three whorls is sjjaringly ornamented with small but ^'ery dis- 

 tinct raised lines or points, something like prostrate hairs, being 

 2iart of and same color as the epidermis." I have observed the 

 same, but the points are not always epidermidal, but sometimes 

 sculpture ' the shell as well, and the peculiarity Binney has de- 

 tected is one of the connecting links between the three ; as to 

 the other links, and the special and general relations of the s]>e--' 

 cies or varieties cited, to others of our California land-snails, X 

 propose to discuss the matter hereaftei-.
