198 THE ZOOLOGIOAL SOCIETY. 



regard to the diseases of monkeys living in this country. The general 

 public hold the belief, endorsed by the medical profession, that nearly all 

 the monkeys brought to England die from tuberculosis. After careful 

 examination, I fail to find any reasonable excuse for so widely spread 

 an error. 



Mr. Blaauw described the development of the horns in the 

 white-tailed gnu ; these weapons, so strangely curved in the 

 adult, are at first quite straight. The contributions of Mr. 

 Jeffery Bell, Mr. Boulenger, Dr. GUnther, Mr. Bowdler Sharpe, 

 and Mr. Oldfield Thomas were chiefly systematic. Emin Pasha 

 sent some interesting letters ; one reports the occurrence of a 

 striped hyena in East Africa, which has recently been confirmed 

 by Herr Schillings. Flower's papers were concerned chiefly 

 with cetaceans ; and those of Howes were, of course, anatomical. 

 Sir Harry Johnston treated of the fauna of Kilima-njaro, Pro- 

 fessor E. Ray Lankester of the heart of the duck-billed platypus 

 and spiny anteater, and here appeared Mivart's classification of 

 the cat-like and bear-like carnivores. Dr. P. Chalmers Mitchell, 

 the present Secretary, read his first paper — a description of an 

 ingenious graphic formula to express geographical distribution — 

 in 1890 ; Mr. R. I. Pocock, the Superintendent, preceded him 

 by three years with a report on the Crustacea collected by the 

 officers of H.M.S. Flying -fish. In 1887 Professor Poulton's great 

 paper on the Protective Value of Colour and Markings in 

 Insects appeared. 



Two volumes of Transactions were published in the decade. 

 The eleventh, which came out in 1885, contained nineteen 

 memoirs. Among these were Flower's contribution on Two 

 British Dolphins, Forbes's on the Sumatran Rhinoceros and 

 on the Californian Sea-lion, and Garrod's on the Brain 

 of the Hippopotamus; Professor E. Ray Lankester's memoir 

 treated of the Muscles and Internal Skeleton of the King-crab 

 and Scorpion ; Owen's papers were on a large extinct Kangaroo, 

 and Dinornis; and Kitchen Parker described the Construction 

 of the Skull in the Chameleon and the Tailed Batrachians. The 

 twelfth volume, with fifteen memoirs, was published in 1890. 

 Perhaps the most important contribution was that of Mr. 

 Beddard and Mr. (now Sir) Frederick Treves on the Anatomy 

 of the Sondaic Rhinoceros.
