Clisocolus cordatus, Whiteaves. 1879. This volume, pt. 2, p. 157, pi. 18, figs. 3, 3, a-b ; 

 but probably not Cyprina cordata of Meek and Hayden (1857) nor 

 Clisocolus duhius, Gabb.

" Tlie identification of the Sucia Islands specimens collected by Mr. 

 Kichardson with the species from the Fox Hills group of Dakota, which 

 was first described by Meek and Hayden as Cyprina cordata, and sub- 

 sequently by Meek as Sphoeriola cordata, has not proved satisfactory, and 

 they seem to be quite distinct from Gabb's Clisocolus duhius " (1896. op. 

 cit. supra.) 



A few specimens, which seem to be referable to C. cordatus, were col- 

 lected in 1901 at Brennan Creek, V.I,, by the Rev. G. W. Taylor ; and 

 at Departure Bay, V.I., by Mr. Harvey.

Mr. Harvey has collected numerous specimens, which, in the writer's 

 judgment, are referable to this elongated variety of C. Conradiana, at 

 North West Bay, Vancouver Island, in 1897 ; from the roof of the coal 

 at the Nanaimo mines, V.I., and at Texada Island, in 1901.
