16. Brown 3 s Travels in British Guiana. 
[Canoe and Camp-life in British Guiana. By 0. Barrington Brown, 
Assoc. R.S.M., late Government Surveyor in British Guiana. 1 vol. 8vo. 
London, Stanford: 1876.] 
This interesting narrative of Mr. Brown's various excur¬ 
sions while executing his office of Surveyor of British Guiana 
is replete with notes and observations on natural history. 
Many of these relate to birds, such as those on Rhynchops 
(p. 95), Chasmorhynchus variegatus (p. 123)*, Sturnella ludo- 
viciana (p. 167), Acanthylis collaris (p. 219), Cancroma co- 
chlearia (p. 257), and Opisthocomus cristatus. Mr. Brown 
is well known to geographers as the discoverer of the cele¬ 
brated Kaieteur waterfall on the Upper Essequibo, which 
appears to be frequented by " myriads of millions " of a large 
Swift [Acanthylis collaris sive zonaris). The nesting-place 
of Steatornis, in a cave on the Upper Mazaruni (see p. 286), 
is, so far as we are aware, quite a new discovery, as are like¬ 
wise the nesting-habits of Ortalida motmot and Odontophorus 
guianensis (p. 371). The explanation of the curiously formed 
wing-feathers of Penelope pipile (p. 387) is likewise new to us. 
17. Ornithological Results of the 1 Gazelle 3 Expedition.

The German S.S. f Gazelle' conveyed the astronomers of 
that nation to Kerguelen's Land for the observation of the 
Transit of Venus in December 1875. A large collection of 
birdskins, birds in spirit, skeletons, and eggs was formed 
during the voyage, principally by Dr. Hiisker, the medical 
officer, in the above-named island, and in other places visited 
during the voyage round the world (Fiji Islands, New Ire¬ 
land, New Hanover, Timor, and New Guinea). Altogether 
examples of 143 species of birds were obtained, which are 
enumerated by Messrs. Cabanis and Reichenow in the present 
* On the discovery of this species in British Guiana, see Ibis, 1869, 
p. 462.
