COLLIER : ON EDGAR LEOPOLD I.AYARD. 



331 



He was very fond of fishing, and after his return from abroad, he 

 went either to Scotland or Ireland every year for a few weeks' fishing, 

 and kept accurate records of the number and weights of fish that he 

 caught. 



Through being abroad so much, and not having access to recent 

 books on natural history or collections, he did not describe many of 

 the species he found as being new to science, but sent them to his 

 friends, who named a considerable number of species after him. 



The following is a list of them, showing they were almost invariably 

 from localities where he collected himself :—

Clausilia biplicata (Mont.) white variety. — In reference to this variety, for 

 which, misled by its omission in text books by British authors, I proposed (autea, 

 p. 232) the name of alba, I find that Westerlund (Fauna Moll. Suec. Norv. et Dan., 

 1873, P- x 9^) describes a var. albina, which he characterizes as " pallidissime 

 virenti hyalina. Paetel, in his well-known "Catalog," also records a variety as 

 albina Bttg. from the " Taunus." Mr. E. R. Sykes informs me that he has for 

 some years past possessed white examples of CI. biplicata from Austria and Bohemia, 

 so the form is evidently familiar to Continental conchologists. Mr. J. W. Taylor 

 (J. Conch., vol. I., p. 216, 1877) records the white variety from Heidelberg under 

 the name of albida, and his name necessarily supersedes mine, but must in turn 

 give place to Westerlund's, that is, of course, assuming that the shells are identical, 

 as they seem to be. The fact of Mr. Mason's Mortlake examples constituting the 

 first record of the occurrence of this beautiful form, as British, yet brought before 

 the society, is very interesting — and perhaps quite as important as the institution of 

 a new " variety." — R. Standen {Read before the Society, Nov. 8th, 1899).
