THE NAUTILUS. 35 



The Mesodon albolabris, from Eureka Springs, are pronounced by 

 Wetherby to be a very distinct variety. He has, also described the 

 two other varieties from the same place, and the exoletus minor 

 from there are said by Mr. Binney to be " very curious." 



The kioivaensis variety, arkansensis, lately described in the Nau- 

 tilus, were collected by Mr. R. A. Blair, near Hot Springs. 



The Goiiiobases were generally very plenty where found at all, 

 and in other streams near by there were none. I have them from 

 many streams. The G. crandalli was collected at Mammoth 

 Spring, and described in the Proceedings of the Philadelphia Acad- 

 emy of Sciences. 



NOTE ON ENDODONTA (Flammulina) INFUNDIBULUM Hombr. & Jacq. 



BY CHARLES HEDLEY, AUSTRALIAN MUSEUM, SIDNEY, N. S. WALES. 



In the " Reference List of the Land and Fresh-water Mollusca of 

 New Zealand " by Mr. H. Suter and myself, the species named above 

 was placed under Flavimulina erebrifiammis Pfr. as a synonym. 

 Tryon and Pfeiffer, whom we followed in this course, were certainly 

 wrong in connecting inj'undibxduin with crebriflammis (Mon. Hel. 

 Viv. iii, p. 148, etc.). H. infundibulum was described from Vavas, 

 Tonga Is., and appears to be a small variety of Gradata Gould. It 

 was omitted from Mousson's Tong-an list. 



NOTES AND NEWS. 



Rev. Dr. A. Dean has removed from Muncy, Pa., to Fort Lee, 

 N. J., on the Hudson, above New York City. The best wishes of 

 many brother Conchologists go with him to his new home on the 

 Palisades. 



An interesting paper on the shells collected by the Death Valley 

 Expedition, by Dr. R. E. C. Stearns, has appeared in the " North 

 American Fauna " series, published by the U. S. Dept. of Agricul- 

 ture. Some pages are given to the discussion of the Tryonias, which 

 were collected alive by Dr. Merriam in a hot spring in Pahranagat 

 Valley, Nevada. The "■Tryonia " j^t'otea is shown to intergrade per- 

 fectly with the smooth form which Frauenfeld called Hydrobia see- 

 maiii. It is a species of Bythinella. Stearns retains Tryonia dath- 

 rata distinct, as he has seen no examples connecting with protea. 

 Several species of Amnicolidee are described and figured, and valu-
