FAMILY HELICID^E 21 



Helix (Arianta) arbustorum L. has been noted as an introduced 

 species, at St. John, Newfoundland, just outside of our region, by 



Whiteaves. 



Genus Epiphragmophora Doering. 



Epiphragmophora fidelis Gray. 



Helix fidelis GRAY, Proc. Zool. Soc. Lond., 1834, p. 67 ; Conch. Cab., 2d 



ed., Mon. Helix, p. 321, pi. LVII, figs. 12, 13. 

 Helix nuttalliana LEA, Trans. Am. Phil. Soc., vi, p. 88, pi. xxm, fig. 74,

 Epiphragmophora fidelis PILSBRY, Class. Cat. N. Am. Landsh., p. 4, 1897. 



Range. Northern California to Sitka, Alaska. 



Sumas Prairie, Fraser River valley, B. C. (common to 6,000 ft., J. 

 K. Lord) ; Chilliwak Lake, B. C. ; Victoria ! Nanaimo ! Comox ! on 

 Vancouver Island; Growler Cove, Broughton Strait; Union Bay! 

 False Bay, Lasqueti Id. ; Malaspina Inlet ; N. point Texada Island, 

 British Columbia ; Sitka, Alaska ! 



The Sitkan and Columbian specimens are apparently not markedly 

 different from those collected further south, and pass through the same 

 color variations. If there is any difference it is that the northern speci- 

 mens are a little smaller and exhibit no tendency to pilosity. The 

 two specimens obtained at Sitka were found near the Hot Springs. 

 There is no evidence in regard to the distribution of the species north 

 of Sitka, but it would not be surprising if it were eventually found to 

 extend on the outer islands as far north as Cross Sound. 



Genus Zoogenites Morse. 



This group has been united with the Acanthinula of Beck, of 

 which, it would seem, little is known but the shell, while we have, 

 thanks to Morse, a very satisfactory account of our mollusk. I prefer 

 therefore to defer any consolidation with Acanthinula until it is shown 

 to be necessary. The information to be had from Moquin Tandon in 

 regard to Acanthinula aculeata is unsatisfactory and insufficient. 

 Westerlund (1902) has proposed a genus Aulaca to contain both 

 (prior) genera !
