510 LETTER FROM MR. W. H. PEASE. [DcC. 8, 



December 8th, 1863. 



E. W. H. Holdsworth, Esq., in the Chair. 



Mr. A. E. Knox made some remarks on the supposed date of ex- 

 tinction of the Mole (Taljpa vulgaris) and the Weasel (Mustela 

 vulgaris) in Ireland. 



Mr. Eraser exhibited the skin of a Leopard from Japan, which he 

 identified as being the Felis (Leopardus) japonensis of Dr. Gray, 

 described and figured in the Society's Proceedings for 1862, p. 262, 

 pi. 33. This, being the second specimen only which had come under 

 the notice of the scientific world, tended to confirm the views of Dr. 

 Gray as to the distinctness of the species. 



The following letter, addressed to the Secretary by Mr. W. H. 

 Pease, Corr. Member, and dated Honolulu, Sandwich Islands, Oct. 1, 

 1863, was read to the Meeting : — 



" Sir, — I have received lately the ' Proceedings of the Zoological 

 Society ' issued during the past three years. On looking over them, 

 I discover a few errors and omissions in the papers contributed by 

 me, which are of sufficient importance to be corrected, viz. : — 



" P. Z. S. 1860, p. 32. — The genus ' Doriprismatica' is so divided 

 in printing, that the species described would appear to belong to the 

 genus Doris. They should stand as ' Doriprismatica imperialist and 

 • Doriprismatica lineata' 



•'P. Z. S. 1861, p. 245. — It appears that I omitted the specific 

 name of the Pleurobranchus here described. It should read 'P. 

 tessellatus' ; and on the following page (246), the Lobiger there 

 described is L. viridis. 



" P. Z. S , 1860. — In the Table of Contents I am credited as being 

 the author of a new genus of Planariidee, bearing my own name ! — 

 ' Peasia,' and several species. The mistake will be explained by 

 referring to the footnote, page 37. I should not consider this of suf- 

 ficient importance to notice, had not one of the editors of the ' Ame- 

 rican Journal of Science and Arts ' fallen into the same error, and 

 taken occasion to publish a very harsh and severe criticism on that 

 paper. 



"Yours &c., 



"W.H. Pease." 



" I also notice that several of the names of the species described 

 in my papers in 1860, have been preoccupied by Dr. Kelaart. I 

 therefore propose to change them as follows : — 



" Doris excavata. Pease, into D. oreosoma. 



" Doris papulosa, Pease, into D. tincta. 



" Pleurobranchus reticulatus, Pease, into P. violaceus,"
