18 Lower Californian Shells. [ZOE 
in that region near some ranch which has since been abandoned 
(like many others), or was never mapped down. The type figured | 
by Forbes was smaller and higher-colored than any variety of the 
species now known from its more northern range, of which ten or 
more have been named by Hemphill and others. Its lost station 
- may be one of the small islands. The blunders of authors that 
were made before 1873 as to this locality are amusing, and it was 
not until then that explorations had proved that the two species 
named must have come from the peninsula, together with the two 
allied forms, while positive locations are only now ascertained. 
‘‘Central America ’’ given by Reeve is about as bad an error as 
Straits of Juan de Fuca. (N. B.—J. R. Browne states that this is 
a real family name, but the San Juan has it de/ meaning “‘ of the.’’) 
17. H. Levis Pfeiffer, 1845. ‘‘ California,’ Hinds. E] Rosario, 
lat. 29° 50’, Orcutt. ‘Columbia River” is another blunder of 
Pfeiffer’s (see Hf. areolata). Varieties indicate that this form may 
intergrade with that and 4. Pandore. It seems limited in range be- 
tween the two forms named. 
+18. H. NEWBERRYANA W. G. B., 1858. San Pedro, Cal., 
lat. 33° 40’, Yates (fossil only?). San Diego, Newberry, lat. 32° 40°. 
South to Ensenada, lat. 3l” 51", Orca, — 
19. H. PANDORA Forbes, 1850. “Santa Barbara as per box 
label” (Carpenter). ‘‘San Juan del Fuaco, Kellett and Wood”’ 
(Forbes). ‘Margarita Island, lat. 24° 2’ (Newcomb, Binney). 
San Quintin, lat. 30° 24’, Orcutt, the only positive location yet ob- 
tained, but is reported from further north. Forbes’ locality is 
explained under 7 Kellettiz, but it is not identified for either species 
lately. The next is probably correct, but conflicts with Pease’s 
statement about HW. areolata. It seems probable that he, as well as 
Gabb, considered this form, like the small form of areolata, merely 
one of the varieties of that species. A damascenus Gould, 1856, 
from ‘‘ Desert east of California, Dr. Frick”? (Newcomb), but not 
confirmed from north of the boundary, 
San Tomas, and is considered a variety of pandore. As to varia- 
tions in this group compare the figures already published. W. G. 
Binney gives copies of the original types in Terr. Moll. of the U. 
S., vol. iv; in Land and Fresh Water Shells he figures quite differ- 
ent varieties of all these species, and Tryon in the Monograph, 3 
was probably from near
