WEST COAST PULMONATA. 21 



type specimen, and for fifty miles or more around there, I 

 am satisfied that it is merely a Landless (perhaps diseased) 

 specimen of one of the large species found there. Mr. 

 Binney remarked its resemblance to A. nickliniana. It is 

 perhaps as near var. bridgesii, which is the prevailing form 

 where it lived, bnt may have been of var. holderiana. Simi- 

 lar accidental defects being found in all the banded spe- 

 cies, it cannot be considered a subspecies, and scarcely a 

 variety. The same may be said of the form called nicklini- 

 ana Lea., a very uncertain type, while var. bridgesii is well 

 defined. Bandless specimens of other forms are sometimes 

 found. 



Mr. Ancey, who is inclined to divide both genera and 

 species too much, has recently made new names for the 

 groups here included in Arionta and (Jampylrea, viz., Hel- 

 mlntlioglypta Ancey, type A. tadiculata Binney, which he 

 says differs much from Arionta (arbustorum) internally, and 

 Micrarionta Ancey, types C? riificincta, C? gahbi and C? 

 facta., which I consider of the same group as C? trasJdi, C? 

 fidelis, etc., though he does not include these. 



From his remarks on these two genera, I conclude that 

 he retains the latter in Lysinoe (but still uses the generic 

 name Aglaia), giving the two new genera as the parallel 

 series to Arionta and Campyloia of Europe. 



A. exarata (Pfeiffer). (No. 35.) 



It was intended to have the name of this shell in the col- 

 umn of species, like Nos. 26 and 30, but the printers put it 

 with the subspecies. Should it yet prove to intergrade 

 with either of the two, it will be with 26, not with 30. 



C. ? (fidelis?) infumata Gould. (No. 36.) 



In his "1st Suppl. to Terr. Moll, of U. S.," Mr. Binney 

 has figured one of the links between the two so-called 

 species here combined as "the smooth form of infumata,''' 

 but does not mention the many intermediate gradations be- 

 tween the two, which perhaps he has not seen. It mav,
