The ANIM.AL does not differ externally from the 

 ordinary eamin-stris, e.xcept being said by Dr. Cooper to 

 be rather more robust than the eastern form ; he also 

 remarks that it is palor in colour when it lirst enu'r^fs 

 from its retreat in the dry season. Intern.\lly the speci- 

 men examined liy ISinney showed a KABUL \ with a 

 formula S.") + 1 + .S."i, with thirteen laterals, the inner and 

 outer lateral teeth occasionally showing a side spur, and 

 approaching in this respect tlie var. iiionfaiius rather than the typical cainjiesfris. 



California — A(/rioh'ii>a.i- camjiciti-is var. ocriilcii/ii/lx, numerous about San Fran- 

 cisco; Santa Cruz; t'lear Lake, aud at Alta, Placer Co., 3,(i2.") feet elevation on the 

 west slope of the Sierra Nevada; also at Trnckee, Nevada t'o. , 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° nortli lat. , to San Juan, near lat. 33', J. G. Cooper, Oct. 

 18S5. A. campesti-is var., Lake Merced, San Fiancisco Co., Mr. Raymond (T. D. A.

Ag^riolimax montanus a typicus T. D. .'\. Cocke 

 Limax ing-ersotti 'W . G. Binney, Proc. .^.c.^d. Nat 



An'IMAL blnish-grey in colour, stout in form, 

 with a blunt iiosterior extremit}', and exceeding one 

 inch in length. 



INTERN.V.LLV, the RADULA shows a formula of 

 504-1 -f50, with sixteen perfect laterals. 



Prof. Cockerell has pointed out that IngersoU'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. moiitninis a ti//iiciis Ckll., 

 which is described as "rather pale brown, foot-sole 

 pale," in all probability represents IngersoU's species 

 wdien living.

Binney describes the RADULA as similar in char- 

 acter to that of /,. iiKiiiiitnitfi, the formula being 

 34-1-1 -)-34, with twelve perfect laterals. 



According to Prof. Coi'kerell, the var. aisfdiirn was described from a yount; 

 example, the black head and tentacles being a feature imparted to alcoholic speci- 

 mens and not existing in li\ ing animals.
