May, 1893.] MOLLUSKS OF THE DEATH VALLEY EXPEDITION. 271 



Glandina texasiana Pfr. 



Brownsville, Tex. (Mus. No. 123573), William Lloyd. 



Two specimens. An ample series of the above, ami the west Mexican 

 G. albersi of the same author, might result in the reduction of the hist 

 to a synonymous position. 



Streptostyla sololensis C. & F. 



Victoria, Tamaulipas, Mexico (Mus. No. 123574), William Lloyd, March 30, 1891. 



"In the Sierra." Though both examples are dead, and one broken, 

 they are sufficient to validate the above determination. The species 

 was described by Crosse and Fisher from Sololo (Guatemala) specimens. 



Limax campestris Binney. 



South Fork of Kern River, California (Mus. No. 123575), Vernon Bailey, July 8, 1891. 



At an elevation of 2,700 feet; a single example. This may be Inger- 

 soll's L. mo Man tis or a variety thereof, which he obtained in Colorado, 

 lugersoll's montanus and montanus var. castaneus, Biimey's ingersirfli 

 and Heynemaun's wienlandi may be regarded, or at least strongly 

 suspected, of close relationship to Biimey's campestris^ which latter may 

 perhaps include Cooper's L. var. occidentalis. • 



Patula striatella Anth. 



Kern Kiver region, California (Mus. No. 123577), Vernon Bailey. 



Numerous living examples at an altitude of 2,700 feet. 



Helix (Arionta) magdalenensis Stearns. 



Johnson Canon, Panamint Mountains, California (Mus. No. 123578), April 11. 1891, 



Dr. A. K. Fisher; also additional specimens in the same region (Mus. No. 



123579), April 18, 1891, Dr. Fisher and E. W. Nelson. 



The foregoing species was described by me in the Proc. U. S. National 

 Museum, Vol. xni, pp. 207-208, from a few examples collected at or 

 near the town of Magdalena, State of Sonora, Mexico, November G, 

 1889, by Mr. Vernon Bailey. He detected it on a hill or mountain at 

 an elevation of about 1,000 feet above the town. The latitude of Mag- 

 dalena is about 31° N. The investigations of the Death Valley Expedi- 

 tion have carried it far to the north of the above, to the Panamint 

 region of California, where both Dr. Fisher and Mr. Kelson obtained 

 numerous living individuals. This discovery extends the area of the 

 distribution of if. magdalenensis northerly between six and seven degrees 

 of latitude. The place where these specimens were found in Johnson 

 Caiion has an elevation of about 6,000 feet above the sea; the first lot 

 (No. 123578) were mostly bleached shells. The Fisher-Nelson series 

 (No. 123579) subsequently collected, is from a still higher elevation, 

 viz, 8,000 feet; here twenty-five living examples were obtained, most 

 of them mature. The Mexican locality may ultimately prove to be 

 about the southerly limit of its distribution. 



Helix (Arionta) coloradoensis Stearns. 



Resting Springs, California (Mus. No. 123907), Vernon Bailey, February 12. 1891. 



A single example, either alive when collected or quite fresh, was 

 detected by Mr. Bailey, who found it among rocks on a dry hill 900
