inch in length, and as nearly as possible the same in breadth at the broadest 

 part of the carapace. They look longer than they are broad, but this is an 

 optical delusion due to the narrowing part of the after part of the carapace. 

 Two of the males and the female when alive were of a uniform rich red- 

 brown over the back. In one about half of the front part of the back was of 

 a pearly white, the rest of tbe carapace being of the same rich red-brown. 

 This one had on either side of the surface of the carapace and on some of 

 its legs parasitical barnacles, each of less than one-twenty-fifth of an inch 

 in length. One of the crabs were of the same rich red-brown, with a bright 

 pearl-white spot behind each eye ; and one had the anterior half of the 

 carapace pearl-white and the posterior part mottled grey. The crabs were all 

 alive when I received them, and, for their size, I never met with any having 

 such great muscular power. I report thus in detail, because I believe the 

 occurrence of this crab has not been before recorded in ' The Zoologist.' —

PROCEEDINGS OF SCIENTIFIC SOCIETIES. 



Linnean Society of London. 



February 2, 1882. — Charles B. Clarke, M.A., Vice-President, in the 

 chair. 



The Rev. B. Scortechini, of Queensland, and Mr. John Marshall, of 

 Taunton, were balloted for and elected Fellows of the Society. 



An extract of a letter from Mr. Thomas Edward, of Banff, was read, 

 and a specimen shown of a supposed rare marine annelid obtained by a 

 fisherman in deep water. It was identified by Dr. Murie as belonging to 

 the Nemertean worms, viz., Cerebratulus angulatus, a marine form found 

 chiefly in the northern parts of the British coasts, but nevertheless seldom 

 seen alive by naturalists. 



Mr. E. M. Holmes exhibited a bottle containing examples of a new 

 blistering insect from Madagascar, belonging to the genus Epicauia and 

 allied to E. ruficollis. It had been brought to this country by Dr. G. W. 

 Parker, physician to the Queen of Madagascar. 



A communication was read from Major-General Benson, particularly 

 referring to Dr. Cobbold's use of the name Fasciola Jacksoni for certain 

 Flukes obtained from the Elephant. These had been described by Major- 

 Gen. Benson, in 1867, in the ' Rangoon Times,' where an account of the 

 epizootic outbreak was first given. Dr. Cobbold thereupon explained that 

 the initials of the author having alone been appended to the article in 

 question, it consequently received less attention than it would otherwise 

 have had, for to Major-Gen. Benson unquestionably belonged the credit of
