85. Hartert on the Birds of Batchian. 



[The Birds of Batjan. By Ernst Hartert. Nov. Zool. x. p. 4$l (1903).] 



Many well-known ornithologists — Wallace, Bernstein, 

 Guillemard, and others — have visited the beautiful island of 

 Batchian and explored, its avifauna, which is closely related, 

 to that of its larger sister Halmahera. The remarkable 

 form Semioptera exists in both of them, but S. halmahera is 

 slightly different from S. wallacii. The materia L lately 

 supplied to Tring by Doherty and Waterstradt, who pene- 

 trated into the high interior, has led to the compilation of the 

 present complete list of the known birds of Batchian, which 

 includes 135 species. Of these Muscicapula hyperythra 

 pallidipectus, Myzomela batjanensis, and Columba albertisii 

 exsid are described as new. ^^v^^ 



86. Hartert on a new Oligomyodian Form. 



[On a remarkable new Oligomyodian Genus and Species from Ecuador. 

 By E. Hartert. Nov. Zool. x. p. 117.] 



Sapayoa (enigma is a new Piprine form, established on the 

 strength of a single female specimen obtained on the Rio 

 Sapayo, in N.W. Ecuador. It appears to be allied to Scoto- 

 thorus (= Heteropelma) , and is of a general olive-green colour, 

 but it is possible that the male may be differently coloured. 



87. Henshaw on the Birds of the Hawaiian Islands. 



[Birds of the Hawaiian Islands, being a complete List of the Birds of 

 the Hawaiian Possessions, with Notes on their Habits. By H. W. Hen- 

 shaw. 8vo. Honolulu, H. T., 1902. 146 pp. Price $1.00.] 



A handbook of the birds of the Hawaiian Archipelago Avill 

 be very useful to the students of that peculiar Ornis, par- 

 ticularly when it is accompanied by such valuable field-notes 

 as Mr. Henshaw gives us in the present memoir. His pre- 

 fatory remarks are also of interest. Mr. Henshaw assigns 

 125 species to the Hawaiian avifauna, of which about half (60) 

 are endemic Passeres. Three Rails are likewise peculiar to 

 the group, the rest of the birds being mostly stragglers from 

 America or species of wide distribution.
