expedition to the Cape Verde Islands, being accompanied 
by his friend Mr. John Duncan and two professional taxi¬ 
dermists. The party landed at Sao Vicente on February the 
10th, and spent about four months in exploring the various 
islands of the group. Materials were thus gathered for his 
excellent and exhaustive paper on the Avifauna of the Cape 
Verde Islands which was published in ‘ The Ibis'’ for 1898, 
pp. 74-118. Some new species rewarded the maiden efforts 
of the explorer, the most important being a curious Lark 
(Spizocurys razed), only met with on the little desert island 
of Raza, which occupies an area of some three square miles. 
Other notable species met with were the Desert Lark 
(Pyrrhulauda nigriceps Gould), the Cape Verde Shearwater 
{P affinus edwardsi Oustal. = P. marice Alexander), the 
White-breasted Frigate-Petrel ( Pelagodroma marina (Lath.) ), 
and Harcourt’s Storm-Petrel ( Oceanodroma castro Harcourt, 
= 0. cryptoleucura Ilidgw.), all of which were found to be 
breeding on some of the small rocky islands. 
Finding that his first visit to the islands had been too 
late for the breeding season of most of the species, he 
paid a second visit to the Cape Verde Islands in 1897 
for the special purpose of obtaining eggs, and his further 
notes on the group were published in f The Ibis 3 for 1898, 
pp. 277-285. 
His next expedition took him to the Zambesi region, when 
he formed one of the nine members of Major Gibbons’s 
4 Cape to Cairo 3 Expedition, which set out from Chindi on 
the 18th of July, 1898. In company with his taxidermist 
Ramm he explored the lower part of the Zambesi and 
its tributary, the Kafue River, and formed a large col¬ 
lection of nearly 1000 bird-skins representing 212 species, 
several of which proved to be new. The results of this 
important undertaking were fully described by Alexander 
in f The Ibis/ 1899, pp. 549-583, 1900, pp. 70-109, 424-458. 
No sooner had he completed his work on the Zambesi 
Collection than be left England for service with the Gold 
Coast Constabulary, and took part in the relief of Kumassi 
in 1900, for which he obtained the medal and clasp. On
