380 DR. J. MURTE ON CERCOPITHECUS ERYTHROGASTER. [June 26, 



The tree was so bulky that he could not climb up the trunk ; but 

 with my assistance he managed to reach the first branch, which was 

 not far from the ground. Here he was again unable to climb up the 

 trunk, and had to go to the end of a branch, and pulling down the 

 branches above dragged himself up by them. However, to cut 

 matters short, he succeeded after some time in climbing to the limb 

 on which the nest was placed, and then, to my great astonishment, 

 out flew the Eagle, which had sat quiet during the whole time we 

 had pelted and fired at the nest. 



Manuel soon reached the nest, and reported that it contained two 

 eggs, and in structure &c. was similar to the last nest, being also 

 lined with fresh green leaves off the same tree in which the nest was 

 placed, some of which he threw down for me to examine. Just 

 below, in a hollow hole, was a nest of Strix flammea, but Manuel 

 could not get at it. The old bird flew out, and I shot it. 



In the foundation of the Eagle's nest were three nests of Passer 

 hispaniolensis, one of which contained five, and another six eggs. 



Manuel had great difficulty in descending, and in one place slipped, 

 unfortunately smashing one of the Eagle's eggs in such a manner 

 that we had to throw it away. These eggs were slightly incubated. 



During the whole' time that Manuel was in the tree, the Eagles 

 circled round above, far out of shot ; but as we were going away the 

 female flew so close that Manuel shot her, which I was sorry for, as 

 I did not wish her to be shot. As it was we did not get her, as she 

 fell into the river and was carried down by the current. 



It being now late in the afternoon we turned our faces towards the 

 railway station, taking, however, another route back, in hopes of 

 finding another nest of Aquila pennata, but met with nothing, ex- 

 cepting one nest of Milvus migrans. We saw a Black Stork (Ci- 

 conia nigra), several Kestrels, three or four Scops Owls, many Serin- 

 finches and Goldfinches, Woodchats, Bee-eaters, and other common 

 birds, but nothing of note. 



8. Supplementary Notes on the. Red-bellied Monkey (Cerco- 

 pithecus erythrog aster, Gray). By James Murie, M.D., 

 Prosector to the Society. 



With the typical specimen of a species, as a matter of future re- 

 ference, it is useful to collect and put on record all details concern- 

 ing it. For this purpose I contribute the following additional slight 

 data on the new species of West African Monkey {Cercopithecus 

 erytkrogaster), of which a notice was given by Dr. Gray in March 

 last (P. Z. S. 1866, p. 1 68). His short graphic diagnostic characters 

 well point out the external peculiarities, leaving nothing to be desired 

 in that respect. 



The admeasurements taken of the dead animal furnish the accom- 

 panying table : —
