82. Finn on Indian Ducks.

This pampUet chiefly consists of reprints o£ articles from 
the 'Asian ' of 1898 and 1899, and treats in Mr. Finn's well- 
known popular style of Ducks in a very wide sense, as the 
author includes therein the Cygninse, Anserinse, Merginse, and 
Anatinse. The Indian species, though most of them breed 
in Northern and Central A^sia, comprise about a quarter of 
the entire family Anatidai ; while most of the residents 
build in trees, and are remarkable for the scanty supply of 
down in their nests. The vernacular names are given as an 
assistance to identification, and appendices are added con- 
taining (1) a diagnostic table, (2) a table of colours of full- 
plumaged males, (3) remarks on the treatment of Ducks in 
confinement.

Polio/ophus nieuwenhuisi, from Central Borneo, is allied 
to Brachypudius {Micropus) melanocephalus , and is dedicated 
to its discoverer Dr. Nieuwenhuis, who has done good work 
for the Levden Museum in Borneo. 
84. Godman's ' Biologia Centrali- Americana.' 
[Biologia Centrali-x-imericana ; or, Contributions to the Knowledge 
of the Fauna and Flora of JVl exico and Central America. Edited by 
F. DuCane Goduian. (Zoology.) Parts CLXIX.-CLXXI. 1901-02. 
(R. H. Porter.)] 
The three portions lately issued of the " Birds '' of this 
important work commence with the Boatbills (Cancromidae), 
which, in accordance with Mr. Ridgway^s views, are regarded 
as forming a family apart from the Herons (Ardeidae) . 
The Central- American representative, Cancroma zeledoni, 
is recognised as distinct from the Southern C. cochlearia, 
but we suspect that intermediate forms may yet be found.
