206 THE ZOOLOGICAL 80GIETY. 



subject of keeping monkeys in the open air, in cages or on 

 the chain, the Field (May 31, 1902) said: 



Owen seems to have advocated this plan. An entry in his wife's diary, 

 under date of October 8, 1840, reads thus : " At K.'s desire, in the Gardens 

 to-day, the monkeys and the elephants were let out to enjoy the sunshine 

 long before the general time, two o'clock." The elephants still possess 

 their old privilege ; and the monkeys — using the term in a wide sense — 

 would probably thrive the better if some means could be devised for 

 "letting them out," 



Sir Henry Blake sent home from Jamaica an adult female 

 manatee and calf. In this case the diflSculties of transport had 

 bad results ; the animals were in an exhausted condition when 

 they reached the Gardens, and died soon after their arrival. 



Two notable birds, new to the collection, were received this 

 year : the Corean sea eagle and the great grebe of Antarctic 

 America. A Goliath beetle was presented, and in exhibiting 

 the insect at the Scientific Meeting of November 7, Dr. Sclater 

 said that, so far as he knew, no living specimen had previously 

 been brought to England. 



Livingstone's eland, distinguished by transverse white stripes 

 on the barrel and a dark brown band above the knee, was 

 introduced in 1894 This form ranks at most as a subspecies ; 

 and Mr. Crawshay, in a paper on the Antelopes of Nyasaland, 

 says that elands are subject to great variation : 



In a single troop individuals may be seen varying from a light tawny 

 yellow to a slaty blue in very old age, while in some the stripes are clearly 

 defined, in others faintly, and in others again they are not distinguishable 

 at all.* 



Bennett's tree kangaroo was another introductioa This 

 species, according to Dr. Sclater, was not sufficiently described ; 

 therefore, at the Scientific Meeting of December 4, he gave a 

 fuller diagnosis. At the same time he exhibited " a photograph 

 of four examples of this rare animal, taken when high up in a 

 leafless tree in the Zoological Gardens at Melbourne." This 

 had been kindly sent by Mr. Le Souef, who described these 

 kangaroos as remaining during the day on the highest branches 

 of a tree, and descending at night to pass from one tree to 

 another. Unfortunately, at Regent's Park these animals were
