The Secretary read the following extract of a letter addressed to 

 him by Babu Ram Bramha Sanyal, O.M.Z.S., dated Zoological 

 Garden, Calcutta, July 27, 1893 :— 



" I am not aware whether closely allied species of Semnopithfci 

 have ever interbred anywhere. They are rather exclusive in their 

 ideas in respect to matrimonial relationship. Anyhow, such an 

 event has just happened in this Garden. The Phayre"s Leaf Monkey 

 (Semnojnthecvs 2^hci>/^'ei, Blyth) has given birth to a young one — a 

 lovely little babe, of a delicate light orange colour. As there has 

 been no other male in the same cage except the S. cristatiis, there is 

 no doubt of the young one being a hybrid between these two species. 

 These Monkeys have been living together since 1880, and although 

 they agreed very well, they were never observed to be over friendly. 

 Even now the male does not appear to take any interest in the 

 offspring." 



A drawing of the mother, and young one at two weeks old, was 

 exhibited. 



In the course of some remarks on the preceding communicatiou. 



Cercopitlicciis lalandii (uiotlier aud young).
