In their shape and surface markings these specimens are apparently 

 very similar to the subcarinate variety of Campeloma productum, White* 

 (which seems to be congeneric with Goniohasis Nehrascensis), but they 

 evidently have a much thinner test, and a much more lustrous and highly 

 polished surface. They are also somewhat similar, both in shape and 

 sculpture to the Tylostoma bulimoides of Stoliczka,t but in the Nanaimo 

 specimens there are no indications of any inner fold-like varices.

The specimens of this species that were described and figured by Meek 

 are from Nanaimo and Comox, as is clearly indicated by the two names 

 cited in the foregoing synonymy. Similar specimens were obtained by 

 Mr. Richardson, two miles and a half up the Nanaimo River, and at 

 Denman Island, in 1872 ; at the Sucia Islands in 1874, and at Admiralty 

 Island in 1875. Quite recently, in 1901, one specimen of D. Nanaimo- 

 ense was collected at Brennan Creek, V. I., by the Rev. G. W. Taylor ; 

 and another two miles and a quarter to two miles and a half up the 

 Nanaimo River, by Mr. Harvey.
