ON THE MIGEATION OF BIRDS. 73 



turns of the observations in the present year. It seems highly desirable 

 that an attempt should shortly be made to analyse, classify, and digest 

 the large mass of facts brought together in these reports, so as to show, 

 statistically and otherwise, the actual results which have been arrived at 

 by the inquiry. It is intended that this shall be carried out at as early 

 a date as possible. 



The Committee respectfully request their reappointment. 



Report of the Coinmittee, consisting of H. Seebohm, E. Trimen, 

 W. Carruthers, and P. L. Sclater (Secretary), appointed for the 

 purpose of investigating the Flora and Fauna of the Cameroons 

 Mountain. 



The Committee have the pleasure of reporting that a successful ascent 

 of the Cameroons Mountain was made by Mr. H. H. Johnston, F.Z.S., 

 F.R.G.S., H.B.M. Vice-Consul for the Cameroons, on their behalf in the 

 autumn of 1886. Mr. Joh iston encamped at Mann's Spring, at an altitude 

 of 7,350 feet, about 300 feet above the forest region of the mountain, and 

 remained there several weeks. A popular account of his expedition has 

 been published with illustrations in the ' Graphic ' newspaper.' 



Mr. Johnston made considerable collections in zoology and botany. 

 The zoological collections have been worked out by specialists in different 

 branches, to whom the collections were referred by the Committee, and 

 the results published in a series of papers in the ' Proceedings of the 

 Zoological Society of London,' of which the following are the titles :— 



1. 'List of Mammals from the Cameroons Mountain, collected by 

 Mr. H. H. Johnston.' By Oldfield Thomas, Proc.Z.S., 1887, p. 121. 



2. ' On a Collection of Birds made by Mr. H. H. Johnston on the 

 Cameroons Mountain.' By Capt. G. E. Shelley, P.Z.S., Proc.Z.S., 1887, 

 p. 122. 



3. ' List of the Reptiles collected by Mr. H. H. Johnston on the 

 Cameroons Mountain.' By G. A. Boulenger, Proc.Z.S., 1887, p. 127. 



4. ' On the Mollusca collected at the Cameroons Mountain by Mr. H. 

 H. Johnston.' By Edgar A. Smith, Proc.Z.S., 1887, p. 127. 



5. ' On some Coleopterous Insects collected by Mr. H. H. Johnston 

 on the Cameroons Mountain.' By Charles 0. Waterhonse, Proc.Z.S., 

 1887, p. 128. 



; It will be observed that although the collections are small they are by 

 no means devoid of interest. Out of eighteen species of birds of which 

 examples were obtained four were new to science, and a new land shell, 

 of the genus Qibbus, was also discovered. 



The zoological specimens have been placed in the collection of the 

 British Museum. 



The botanical specimens collected by Mr. Johnston were sent by the 

 Committee to the Kew Herbarium, where they were placed in Prof. 

 Oliver's hands for determination. As was to be expected, although the 

 specimens were in many cases acceptable, they have added very little to 

 our knowledge of the flora of the Cameroons Mountain. With few ex-
