4. B. GAsBsr Crosse & Fischer, 1872. Locality unknown, and 
only one specimen known, which has characters between those of 
B. pallidior and B. proteus. These two allied forms are not re- 
ported from any one locality except Cape St. Lucas, therefore a 
hybrid theory cannot now be proved. It may provea variety, if B. 
vegetus Gould, which is also intermediate, is not a good species. | 
5. B. INSCENDENS W. G. B., 1891. ‘‘ Cape St. Lucas and 450 
miles up west coast’’ (Cedros Is. lat. 28° 02’ not confirmed), Xan- 
tus. . 
_ Var. Bryanti J.G. C., 1891. San José del Cabo, lat. 23° 24”, 
to La Paz, lat. 24° 12’. The east coast form, more developed. 
6. B. PALLIDIOR Sowerby, 1833. ‘‘ Chili,’’ Ceming (Pfeiffer). 
“West coast of peninsula for 350 miles north (to Ballenas Bay, lat. 
26° 45, not confirmed), Xanéus. La Paz, Maj. Rich. San Juan, 
east coast, lat. 26° 20’, Lt. Greene, type of B. vegetus Gould, 1853- 
Near San José del Cabo to La Paz, Bryant. ‘‘ San Diego” (Car- 
penter), not confirmed. _ Perhaps imported from Chili into gardens 
with roots, and has since died out northward. No other collectors 
seem to have found any Budimuli on west coast north of lat. 25°. 
Mr. Binney mentions several species carried about with roots of 
banana, etc., from one country to another, and this may account 
for the introduction of this and 2. proteus on to the peninsula. 
7. B, pILULA W. G. B., 1861. Todos Santos, lat. 23° 25’, to 
Margarita Island, lat. 24° 20°, Xantus. San José del Cabo, Bryant. 
8. B. proteus Broderip, 1832. ‘‘ Peru and Chili,’’ Coming ?, 
(Pfeiffer). ‘‘Cape St. Lucas,” Xantus. Northern Peru, Orton, 
(Binney). Perhaps another importation as with B. pallidior. The 
question of their importation as food is yet undecided. 
g. B. SPIRIFER Gabb., 1867. Near La Paz, lat. 24° 10’, to San 
Borgia near lat. 28° 40’, among rocks, in the mountains near east 
coast, Gabb. San Borgia is a little west of the middle line in cross- . 
ing the peninsula, and thus the most northern and western locality 
for Bulimuli as yet well authenticated. It is about 450 miles from 
the cape, and may possibly have furnished Xantus with northern 
specimens, which could be mistaken for 2. pallidior. With such 
an extensive range near the east coast it is strange that nobody had 
found it before. Gabb’s figure is more like B. pal/idior than Bin- — 
ney’s. io
