VOL. Ul. | Lower Californian Shells. 21 
“P. heterostropha Say,” 1817, is said by Stearns to be from ‘‘ Hot 
Springs, Lower California, Orcuit.’’ 
ae PupA CALAMITOSA Pilsbry, 1889. San Tomas, lat. 31° 
5’, Hemphill. (To lat. 31°? and San Diego, Orcutt. Twospecies — 
are mentioned by Orcutt without specific names, probably this and 
P. hemphiilt.) 
31. P. CHORDATA Pfeiffer, 1856. Sinaloa, Mex., near lat. 26°? 
(type). San Quintin Bay, lat. 30° 24’, “on salt marsh,’’ Orcutt. 
In habits’is a link towards A/elampus and Pedipes. From ability to 
bear salt, it can inhabit. the driest zone. 
‘“P. orcutti Pilsbry,” named by Orcutt, in the West Amer. Sci- 
entist, October, 1891. p. 270. is probably a synonym of P. chordata, 
as I find no other notice of such a species. 
32. P. HEMPHILLI Sterki, 1890. San Diego to San Tomas, 
Flemphill. 
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, 7: 
Bland. 
Subsp. RAMENTOSA J. G. Cooper, 1891. Mountains north of San 
José del Cabo, one dead shell in a cave, Bryant. It may prove to 
be now extinct. 
35. SUCCINEA OREGONENSIS Lea, 1841. Oregon, (types) and 
south to lat. 31°, Orcuit. Also Vancouver Island, G. W. Taylor. 
36. VERONICELLA OLIVACEA Stearns, 1871. Nicaragua, west 
slope, A/cNeil (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 them, 
referring to Binney’s work for further information, they being be- 
yond the scope of this article. I add also three non-pulmonates 
that belong to a genus sometimes inhabiting fresh or brackish water 
in estuaries. 
“ Zonites diegoensis’’ Hemphill, 1892, a minute /fe/icoid, from 
Cuyamaca Mountains, at 4,500 feet altitude, east of San Diego 
may also be looked for southward.
