82. FiJin on Indian Ducks.

This pamphlet chiefly consists of reprints of articles from 

 the ' Asiaa ' of 1898 and 1899, and treats in Mr. Finn's well- 

 known popnlar style of Ducks in a very wide sense, as the 

 author includes therein the Cygninse, Anserinse, Merginse, and 

 Anatinae. The Indian species, though most of them breed 

 in Northern and Central A.sia, comprise about a quarter of 

 the entire family Anatidae ; while most of the residents 

 build in trees_, aud 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 fuU- 

 plumaged males^ (3) remarks on the treatment of Ducks in 

 confinement.

Poliofophus 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 Leyden Museum in Borneo. 



SJ'. Godman'a ' Biologia Centr all- Americana.' 



[Biologia Centrali-Americana; or. Contributions to the Knowledge 

 of the Fauna and Flora of JNJexico and Central America. Fdited by

The three portions lately issued of the " Birds " of this 

 important work commence with the Boatbills (Cancromidse), 

 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. cochltaria, 

 but we suspect that intermediate forms may yet be found.
