Habitat : Lieu-Chieu. 



Castanea, ad sutttram luteo fasciata, apertura intus fitsca, lamella sub- 

 columellaris non tarn etnersa quain iji for/na typica. 



This variety differs from the type in its dark chestnut colouring with light 

 yellow sutures, in place of the uniform yellow : the lamella sub-columellaris is not 

 so prominent, and the interior of the mouth is dusky in place of white. The 

 shell is more inflated than the typical form. 



I have a specimen from the Morelet Collection, and there are two in the 

 British Museum from the Cuming Collection. Probably many others are known.

Note on the Genus Phenacarion. 



On page 86 of the December number, Mr. Collinge refers to the questionable 

 validity of this genus. Full information regarding it may be found in Mr. W. G. 

 Binney's 3rd and 4th Suppls. to Terr. Moll. U.S. (1890 and 1892), where the two 

 known species are figured, with their genitalia, &c. It may, however, be worth 

 while to publish the following notes on the subject, which I wrote before I left 

 Colorado, but have kept in MS. When these were written, Mr. Binney's latest 

 work, in which a different view is taken, had not appeared. 



I'll KNACAK ION. 



This genus, founded on foliolatus, Could, and var. hemphiffi, W. G. Binney, 

 may be r< garded as a subgenus of Prophysaon. The presence of a mucous-pore 

 can hardly perhaps suffice to distinguish a genus, and there are no other characters 

 of generic value. 



In Europe, the subgenus Isselia, Bourguignat, of Daudebardia is founded on 

 a similar distinction. 



Some forms seem rather intermediate between Prophysaon proper and 

 Phenacarion. Mr. Binney writes that five out of fifty examples of a Prophysaon 

 found by Mr. Hemphill on San Juan Island, show some sort of a caudal pore. 

 Prophysaon andci soni, ]. G. Cooper was supposed to have some sort of a caudal 

 pore, and indeed, a living example of form marmoratitm sent me by Dr. Cooper 

 had a kind of pit at the tail, probably a rudimentary pore. 



A specimen of foliolatus, found by Mr. Hemphill at Seattle, and sent to me 

 by Mr. Binney, seemed to have a distinct functional pore, which appeared in the 

 contracted slug as a crescentic groove, with its concave side upwards. Mr. Binney 

 sent me some specimens of foliolatus var. hemphilla from near the mouth of the 

 Chehalis River, but they were very much dried up. So far as I could judge, 

 they seemed of the same species as foliolatus, but the figure and description in 

 Mr. Binney's 3rd Suppl. Terr. Moll, of hemphilli certainly appear to indicate 

 a distinct species. 



It is now regarded as a distinct species by Mr. Binney. — T. D. A. Cockerell,

Some New Forms of Slugs. 



(1) Prophysaon andersoni var. suffusum, v. nov., 25 millm. long (in alcohol), 

 like P. hemphilli, but reticulations of body more sub-divided, regular, and distinct. 

 Colour grey-black, without markings, sides and edge of mantle paler. Sole pale 

 greyish ochreous, conspicuously transversely wrinkled. Jaw dark, ribbed. 

 Genetalia as in P. hemphilla (which I consider a variety of andersoni), penis-sac 

 remarkably short and thick, not at all tapering ; hermaphrodite gland black, 

 imbedded in liver. 



Chehalis, Washington, U.S.A., one specimen, collected in 1SS9 by Mr. Hemp- 

 hill, and sent to me by Mr. W. G. Binney.
