434 THE ZOOLOGIST. 



A communication was read from Mr. 0. Thomas, containing the 

 description of a new Monkey of the genus Semnopithecus from Northern 

 Borneo, which he proposed to call S. everetti, after Mr. A. Everett, its 

 discoverer. 



Mr. G. A. Boulenger read a description of a Blenuioid fish from 

 Kamtschatka belonging to a new generic form, and proposed to be called 

 Blenniophidium petropauli. The specimen had been obtained in the harbour

Mr. S. Stevens exhibited, for Mr. J. Harrison, of Barnsley, and read 

 notes on, a beautiful series of Arctia lubricipeda var. radiata, which had been 

 bred by Mr. Harrison this year. 



Mr. G. T. Bethune-Baker exhibited specimens of Polyommatus dispar 

 var. rutilus, taken in England by his father about sixty years ago. He 

 stated that it was generally believed that this form of the species was 

 confined to the Continent, but his specimens proved that it formerly 

 occurred in England. 



Mr. C. G. Barrett exhibited dark varieties of Acronycta leporina, bred 

 by Mr. J. Collins, of Warrington ; also a white variety of Triphcena pronuba, 

 taken at Swansea by Mr. W. Holland. 



Mr. M. Jacoby exhibited a specimen of Sagra femorata, from India, with 

 differently sculptured elytra, one being rough and the other smooth. 



Mr. J. A. Clark exhibited a long series of remarkable varieties of Liparis 

 monacha, bred from a pair taken at Scarborough. Several of the 

 specimens were as light in colour as the typical form of the species ; others 

 were quite black ; and others intermediate between these two extremes. 



The Rev. J. Seymour St. John exhibited a monstrosity of Abraxas gros- 

 sulariata, and a specimen oiTaniocampa stabilis, with a distinct light band 

 bordering the hind margin of the upper wings. He stated that he had bred 

 both specimens.

 which had been subjected to dark and light surroundings respectively. The 

 results were seen to be completely negative, the two series being equally 

 light. 



Mr. F. Merrifield showed a number of pupae of Pierls napi. About 

 eight of them, which had attached themselves to the leaves of the cabbage 

 plant on which they were fed, were of a uniform bright green colour, with 

 light yellowish edgings ; of the others, those which had attached themselves 

 to the black net covering the pot, or the brownish twigs which supported
