"/*. heterostroplia Say," 1817, is said by Stearns to be from " Hot 

 Springs, Lower California, Orcutt^ 



30. Pupa calamitosa Pilsbry, 1889. San Tomas. lat. 31° 

 35', Hemphill. (To lat. 31*"? and San Diego, Orcutt. Two species 

 are mentioned by Orcutt without specific names, probably this and 

 P. hemphilli.) 



31. P. CHORDATA Pfeiffer, 1856. Sinaloa, Mex., near lat. aG""? 

 (type). San Quintin Bay, lat. 30^24', "on salt marsh," Orcutt'. 

 In habits is a link towards Melampus and Pedipes. From ability to 

 bear salt, it can inhabit the driest zone. 



"/*. orcutti Pilsbry," named by Orcutt, in the West Amer. Sci- 

 entist, October, 1891. p. 270. is probably a synonym oi P. chordata, 

 as I find no other notice of such a species. 



32. P. HEMPHILLI Sterki, 1890. San Diego to San Tomas, 

 Hemphill. 



33. P. OVATA Say, 1822. Across the continent in nearly every 

 State. San Diego south to lat. 31°, Orcutt. 



34. Rhodea californica Pfeiffer, 1846. "Monterey, Cali- 

 fornia," (Pfeiffer), certainly an error. Bogota, New Grenada, T: 

 Bland. , 



Subsp. RAMENTOSA J. G. Cooper, 1 89 1. Mountains north of San 

 Jose del Cabo, one dead shell in a cave, Bryant. It may prove tp 

 be now extinct. 



35. SucciNEA OREGONENSis Lea, 1841. Oregon, (types) and 

 south to lat. 31*^, Orcutt. Also Vancouver Island, G. W. Taylor. 



36. Veronicella olivacea Stearns, 1871. Nicaragua, west 

 slope, McNeil (types). Lower California, Hemphill. " Lobitos 

 Creek, California, lat. 36° 52'," Stearns. This locality has been re- 

 cently searched for them in vain by Raymond (1891). 



This fresh-water slug leads to the salt-water pulmonate Onchidellas> 

 etc. , which I merely catalogue, as nothing new is to be said of themi 

 referring to Binney's work for further information, they being be- 

 yond the scope of this article. I add also three non-puhnonates 

 that belong to a genus sometimes inhabiting fresh or brackish water 

 in estuaries. " ■ 



" Zonites die^^oensis" Hemphill, 1892, a minute Helicoid, irom 

 Cuyamaca Mountains, at 4,500 feet altitude, east of San Dieg<i 

 may also be looked for southward. '•
