4 COCKERELL : A FEW NOTES ON SLUGS. 



Mr. Win. Cradwick sent me many alive ; they looked 

 like campestris ; in alcohol, all showed more or less mottling. 

 Jaw bright-coloured, with a strong median projection. 



It is possible that this slug is native in Jamaica, and 

 that the Jamaica and Bermuda specimens may all 

 represent a distinct West Indian race. 



(3.) A parasite of A. laevis (s. lat.). In a specimen collected 

 in 1889 by Mr. H. F. Wickham at C)uincy, California, 

 apparently referable to the form hyperhorcons, Westerl., 

 I found a small parasitic worm, belie\"ed to belong to the 

 genus Lcptodcra. 



(4.) A. berendti var., pictus. This was figured by Mr. 

 I)inney from a specimen collected by Hemphill on the 

 bank of the San Tomas Riv'er, Lower California. Length 

 (in alcohol) about 10 mm., body paler than in var. 

 Jicmpliilli, inclined to be reticulate, mantle with black 

 spots and blotclies ; shell stjuarish at entls, obscurely 

 keeled as in hcrendti, growthdines obscure. Penis-sac 

 apparentl}' as in cainpcstyis. 



(5.) A. campestris in New Mexico. Last year I found this 

 slug on the Mescalero Indian Reservation, in the 

 Sacramento Mts., just above the agency. This is the 

 third locality recorded in New Mexico. 



LIMAX. 



(6.) L. maximus in Madeira. The British Museum contains 

 seven specimens from Madeira, two var. cellarius from 

 Baron C. de Paiva, two var. johiistoni and two var. moqnini 

 from Mr. Mason, and one var. cellarius collected by 

 ]\Ir. L. M. Cockerell. There is also a cellayius from Lowe. 



(7.) L. cinereoniger, variety. A specimen collected by 

 Mr. F. G. Fenn in August, 1890, at Echternach, Luxem- 

 bourg (along with Arion ater var. lamarckii and A. suhfitscus 

 var. riifofiisciis) agrees almost exactly with var. siahilei, 

 Less., differing only ia having the sides mottled with 

 grey, instead of black, and the lateral areas of the sole 

 grey instead of brownish ; keel pale for about f of the 

 back. The var. niger, D. and M., is almost identical.
