GEOGRAPHICAL DISTRIBUTION. 21 



described from that region under the name of //. Remondi, and from 

 Gua^'mas. Veronicetla olivacea, Stearns, a Nicaraguan species, is also 

 said to extend into California. I should also mention that Binneya 

 notahilis has been found on Guadalupe Island, off the coast of Lower 

 California. 



From the list of California species are omitted Columna Calif ornica, 

 actually collected at Marmato, New Granada, by Mr. Bland, and Zonites 

 cuUtllatus, probably an accidentally introduced European shell. Jhili- 

 rmis Californicus is also omitted, belonging, no doubt, to the region of 

 Mazatlan. Also Glandina Albersi, which we know to live in the Sierra 

 Mad re. 



Separate lists of species peculiar to the several regions of the Pacific 

 Province are given above. There now follows a complete list of all the 

 species hitherto observed in the entire Province. 



Macrocyclis Vancouverensis. Vitrina Pfeiflferi. 



sportella. Limax campestris. 



Voyana. Hewstoni. 



Duranti. Prophysaon Hemphilli. 



Zonites Whitneyi. Ariolimax Columbianus. 

 arboreus. Californicus. 



indentatus. niger. 



minusculus. Hemphilli 



milium. Andersoni. 



conspectus. Arion ? foliolatus. 

 chersinellus. ? Andersoni. 



StearnsL Binueya notabilis. 



fulvus. Hemphillia glandulosa. 



common to the peninsula and mainland of Mexico. The most interesting fact in the fauna 

 of Lower California is the presence of Bulimuhis proteus and B. pallidior, — species de- 

 scribed originally from South America, the former from Chili. Such facts can only be 

 accounted for by a theory of former connection of the two points. 



Though still more remotely connected with the subject of this paper, it will be inter- 

 esting to add here a list of species found at and north of Mazatlan, on the Pacific coast of 

 Mexico. 

 Glandina turris, Pfr. Polygyra acutedentata, W. G. Binn. 



Albersi, Pfr. ventrosula, Pfr. 



Holospira Remondi, Gahb. Bulimulus Ziegleri, Pfr. 



Patula Mazatlanica, Pfr. Californicus, Rve. 1 



Arionta Carpenteri, Newc. Orthalicus undatus, Brug. 



Polygyra anilis, Gahb. Pupa chordata, Pfr. 



Behri, Gahb. Succinea cingulata, Forbes. 



Of the above, P. Mazatlanica has lately been quoted from San Francisco, confounded 

 ■with some allied species, as I have since learned. 



A. MoTinoynim is omitted frorfi this list, its presence in Sonora not having been con- 

 firmed, although asserted, doubtfully, by Messrs. Fischer and Crosse.
