This specimen had been obtained about 75 miles from Denver, Colo- 

 rado, in 1875. 



The Secretary exhibited, on the part of Mr. A. Anderson, F.Z.S., 

 a Bamboo driving-stick with leather thong attached, which had been 

 taken out of the nest of an Indian Fish-Eagle (Haliaetus leucory- 

 phus) in December 1876. 



A communication was read from Prof. J. O. Westwood containing 

 a synopsis of the Uraniidae, a family of Lepidopterous Insects, to- 

 gether with a complete monograph of Coronilia, one of the genera 

 of which it is composed. 



This memoir will be published entire in the Society's " Transac-
