134 AGRIOLIMAX LAVIS CAMPESTRIS. 
Var. occidentalis Cooper, Proc. Acad. Nat. Sci. Philad , 1872, p. 146, pl. 3. 
The ANIMAL does not differ externally from the 
ordinary campestris, except being said by Dr. Cooper to 
be rather more robust than the eastern form ; he also 
remarks that it is paler in colour when it first emerges 
from its retreat in the dry season. INTERNALLY the speci- Fic. 149)—WWertanpeinteral. 
men examined by Binney showed a RADULA with @ — and marginal teeth of A. cam- 
formula 35 +1435, with thirteen laterals, the inner and — Aestrts_v. occidentalis, highly 
outer lateral teeth occasionally showing a side spur, and — ™@8nified (after Binney). 
approaching in this respect the var. monfanus rather than the typical campestris. 
California—Agriolimax campestris var. occidentalis, numerous about San Fran- 
cisco; Santa Cruz; Clear Lake, and at Alta, Placer Co., 3,625 feet elevation on the 
west slope of the Sierra Nevada; also at Truckee, Nevada Co., 5,866 feet high on 
the east slope. It has also been found on the Coast Mountains, and along the coast 
almost everywhere, from 39° north lat., to San Juan, near lat. 33°, J. G. Cooper, Oct. 
1885. A. campestris var., Lake Merced, San Francisco Co., Mr. Raymond (T. D. A. 
Cockerell, J. of Conch , Oct. 1891).

Limax ingersolli W.G. Binney, Proc. Acad. Nat. Sci. Philad., 1875. 
ANIMAL bluish-grey in colour, stout in form, 
with a blunt posterior extremity, and exceeding one 
inch in length. 
INTERNALLY, the RADULA shows a formula of 
50+1+450, with sixteen perfect laterals. 
Prof. Cockerell has pointed out that Ingersoll’s 
description was probably made from spirit specimens, 
and that the bluish-grey colour was due in great part 
to an exudation of slime, such as is often observed 
in alcoholic specimens ; A. montanus a typicus CkIL., 
which is described as ‘rather pale brown, foot-sole 
pale,” in all probability represents Ingersoll’s species 
when living. 
Montana—L. monfanus, one at Missoula, June 
1897 (M. J. Elrod, Nautilus, March 1902, p. 129). 
Utah—L. montanus (H. A. Pilsbry, Proce. Acad. Nat. Sci. Philad., 1889, p. 196).

(T. D. A. Cockerell, Moll. Colorado, J. of Conech., Jan. 1889). Hot sulphur springs, 
Grand Co., Mr. Ingersoll; Custer Co. ; Chaffee Co. ; Canon City, Fremont Co. ; 
Summit Co.; Eagle Co, ; Mesa Co. ; and Gunnison Co. (id., Naut., Jan. 1890, p. 100).

According to Prof. Cockerell, the var. castanea was described from a young 
example, the black head and tentacles being a feature imparted to alcoholic speci- 
mens and not existing in living animals.
