THE ZOOLOGICAL SOCIETY'S GARDENS. 



During the month of May the number of Chimpanzees exhibited 

 in the Gardens amounted to eleven, a record for this or any other 

 menagerie. One out of the three new examples recently added was 

 from Uganda, and is peculiarly interesting on account of the decided 

 rufous tinge pervading the tips of the hairs. From the same locality 

 came a specimen of that rare red-crowned, white-bearded species of 

 Guenon, described as Cercopithecus neglectus, which is one of the many 

 forms of animals occurring both in Uganda and West Africa. It 

 is generally associated systematically with the better- known Diana 

 Guenons, of which two well-marked races inhabit West Africa, namely, 

 the one with red thighs (C. dia?ia, sensu stricto), and the one with 

 white or lemon-yellow thighs (C. diana roloivay). Two examples of 

 the latter were presented during the month ; as well as the second 

 specimen we have received within the last twelve months of the rare 

 Nigerian Green Guenon, G. pousarguei. From West Africa we have 

 also acquired two pretty little Duikers, the crowned {Qephalophus 

 coronatus) and Maxwell's (C. maxwelli). It is interesting to compare 

 the difference in colour between these two, which are kept in the same 

 enclosure ; Maxwell's Duiker being of a rich slate-grey tint, and the 

 crowned the ordinary tawny tint with black and white markings, so 

 prevalent in Antelopes as a whole. 



Probably the most attractive additions amongst the Mammalia are 

 five Prairie Dogs or Prairie Marmots (Cynomys ludovicianus), sent by 

 Mr. Hornaday, the Director of the New York Zoological Park. Apart 

 from their quaint behaviour, these animals are interesting on account 

 of their association in their natural haunts with a species of small 

 Burrowing Owl (Speotyto cunicularia) , a bird which takes possession of 

 the burrows of other animals, sometimes of the Marmot, sometimes 

 of the Ground Squirrel or Souslik in North America, and sometimes 

 of the Viscacha in South America. In the Gardens, the Prairie Dogs 

 have been placed, with two of these Owls, in a sand-covered enclosure, 

 where the two species may be seen living side by side. 



For the last few years Sloths have b.een represented in the Gardens 

 by an example of Hoffmann's two-toed species (Cliolcepus hoffmanni). 

 Within the last few days, however, a specimen of the three-toed species 

 (Bradypus tridactylus) has been purchased. Curiously enough, examples 

 of this animal have never done well in Regent's Park, on account of 

 the difficulty of getting them to feed. The one in question has, how- 

 ever, made a favourable start, and after being fed for a couple of days
