236 THE ZOOLOGIST. 



Mr. F. E. Beddard read some notes on various species of aquatic 

 Oligochaetous Worms that he had lately had an opportunity of examining. 

 Amongst these was a new form allied to Acanthodrilus from the saline 

 waters of the Pilcomayo, discovered by Mr. Graham Kerr during the 

 Pilcomayo Expedition. 



Dr. Hans Gadow read a paper on the systematic position of Notoryctes 

 typhlops, the newly-discovered marsupial of Central Australia, and came to 

 the conclusion that this anomalous form should stand as a distinct family 

 of Polyprotodont Marsupials allied to the Dasyuridce and the Peramelidce. 



A communication was read from Capt. H. G. C. Swayne, R.E., containing 

 field-notes on the Antelopes of Northern Somali-land. 



Mr. W. Schaus read the second portion of his descriptions of new species 

 of Lepidoptera Heterocera from Brazil, Mexico, and Peru. 



Mr. W. L. Sclater read some notes on certain species of Frogs in the 

 Indian Museum, Calcutta, and gave descriptions of several new species based 

 upon some of these specimens. — P. L. Sclater, Secretary. 



Entomological Society of London. 



April %Jth, 1892.— Robert McLachlan, F.R.S., Treasurer, in the 

 chair. 



Mr. William Edward Baily, of Lynwood House, Paul Churchtown, 

 Penzance; and Mons. Edmond Fleutiaux, of 1, Rue Malus, Paris, were 

 elected Fellows of the Society. 



Mr. C. G. Barrett exhibited, for Mr. Sabine, varieties of the following 

 species : — viz., one of Papilio machaon, bred by Mr. S. Baily, at Wicken, in 

 1886 ; one of Argynnis lathonia, taken at Dover in September, 3 883 ; one of 

 A. euphrosyne, taken at Dover in 1890 ; and one of A. selene, taken at St. 

 Osyth, in 1885, by Mr. W. H. Harwood. He also exhibited a long series 

 of Demas coryli, reared by Major Still from larvae fed exclusively on beech, 

 which he said appeared to be the usual food of the species in Devonshire, 

 instead of hazel or oak. Mr. Barrett also exhibited, for Mr. Sydney Webb, 

 a number of varieties of Arge galathea, Lasiommata megcera, Hipparchia 

 tithonus, and Ccenonympha pamphilus, from the neighbourhood of Dover. 



The Rev. J. Seymour St. John exhibited a variety of the female of 

 Hybernia progem?naria, taken at Clapton in March last, in which the par- 

 tially developed wings were equally divided in point of colour, the base 

 being extremely dark and the outer portion of the wing very pale. 



The Rev. Canon Fowler made some remarks on the subject of pro- 

 tective resemblance ; he said his attention had been recently called 

 to the fact that certain species of Kallima apparently lose their protective 

 habit in some localities, and sit with their wings open, and that Dr. A. R. 

 Wallace had informed him that he had heard of a species of Kallima sitting
