 Dear Sir Gray's Inn, Oct. 4th, 1902. 



In the Octohex Journal (p. 247), I notice amongst the 'Exhibits' the 

 following: "By Mr. Cairns: Planorbis dilatatiis, discovered in the collec- 

 tion of the late Mr. T. Rogers, and, judging from the label, evidently the 

 original specimens taken by him in 1869, and sent to Gwyn Jeffreys for identi- 

 fication. These historic specimens passed into Mr. Cairns' hands on the 

 acquisition of xMr. Rogers' collection by Mr. H. B. Preston." 



There appears to be some misapprehension. Mr. Rogers was, as will be 

 known, in the habit of mounting his collection partly on glass slides, and 

 when Mr. Preston acquired the collection one glass slide, now in my posses-

 (i) Ten specimens labelled " Plaitorbis dilatatus Gould, Bolton Canal, 

 June, 1869." 



(2) One specimen labelled '' Planorbis dilatatus Gould, N. America, from 



Jeffreys." 



(3) Twelve specimens labelled '' Planorbis dilatatus Gould, canal, Gorton, 



Aug., 1869." 



The above details relating to the date and locality of the British speci- 

 mens agree with those given in the Journal (vol. i, p. 81). 



Mr. Preston informs me that he acquired the entire collection, save for a 

 few South African shells, and that he has not, so far as he is able to trace, 

 sent any specimens of P. dilatatus to Mr. Cairns, as might be inferred from 

 the paragraph which I have quoted above. No doubt the species was taken 

 plentifully, l:>ut I think this statement shows that Mr. Rogers' " historic
