22 A MANUAL OF AMERICAN LAND SHELLS. 



It may, liowever, belong rather to the Lower California fauna,* having 

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

 from Guaymas. Yeronicella olivacea, Stearns, a Nicaraguan species, is 

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

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

 California, from whence it has probably been introduced. 



From the list of California sj)ecies are omitted Columna Californiea, 

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

 cultellatus, probably an accidentally introduced European shell. Buli- 

 mus Ccdifornicus is also omitted, belonging, no doubt, to the region of 

 Mazatlan ; also Glandina Albersi, which we know to live in the Sierra 

 Madre. 



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



* The peninsula of Lower California forms a distinct molluscous province of itself, 

 extending nearly to San Diego. The following species are peculiar to it : 

 Coelocenirtim irregulare, Gabb. BuUmulus pallidior, Sowerby. 



Arionia Slearnsiana, Gabb. excelsus, Gould. 



BoweUij'Nev^e. {Lohri, Gabb). inscendens, W. G. Binn. 



Euparypha areolata, So\fh. {Veitchii, sufflatus, GonlA. 



Newc). piJula, W. G. Binn. 



Pandoi'W, Forbes. proteus, Brod. 



levis, Ffr. Xaniusi, W. G. Binn. 



Berendtla Taylori, Pfr. artemisia, W. G. Binn. 



Bulimus spirifer, Gabb. 

 Gahhi, Crosse. 

 VcroniceUa olivacea, Stearns, a Nicaraguan species, is also found in Lower Califor- 

 nia. Of the above list one only has been found near San Diego, A. Steantsiana. 

 Aaother, A. EoweUi, has been referred to Arizona, but erroneously. E. Pandoras 

 and areolata have also erroneously been referred to California. A. Eemondi (Car- 

 penteri) is omitted from the list, as it also occurs in the California Region. It is the 

 only species common to the peninsula and mainland of Mexico. The most interest- 

 ing fact in the fauna of Lower California is the presence of Bulimnlus proteus and 

 B. pallidior — species described originally from South America, the former from Chili. 

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

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

 coast of Mexico : 



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



Albersi, Pfr. ventrosnla,Fh. 



Holospira Remondi, Gabb. BuUmulus Zieglcri, Pfr. 



Patula Mazatlanica, Pfr. Californicus, Eve ? 



Arionta Carpertterif'Newc. Orthalicus nndatiis, Brug. 



Polygyra anilis, Gabb. Pupa chordata, Pfr. 



Beliri, Gabb. Succinca cingulata, Forbes. 



Of the above, P. Mazatlanica has lately been quoted from San Francisco, but I find 

 the specimens so called to be delicate individuals of Zonites conspectus; (see that spe- 

 cies). 



A. Mormonum is omitted from this list, its presence in Souora not having been con- 

 firmed, although asserted, doubtfully, by Messrs. Fischer and Crosse (see under that 

 species in the descriptive portion of the text).
