species and some 50 or 60 subspecies of Trochilidse are now 

 known. The largest special collection of this group is that 

 of John Gould^ now in the British Museum (5378 examples) ; 

 the two next, probably, those of Salvin and Godman and of 

 Mr. D. G. Elliot ; and the fourth in extent that of the author 

 (about 2000 examples of 350 species and 30 subspecies). 



3. W. Blasius on the Birds of Celebes. 



[Beitviige zur Kemitniss der Vogelfauna von Celebes. II. Von Prof. 

 Dr. Willi. Blasius. Zeitschr. f. d. ges. Ornithologie, 1886, Heft ii.] 



In this memoir Dr. W. Blasius gives a full account of a 

 collection formed in Minahassa, Northern Celebes, by Mr. 

 Riedel in 1865 and 1867, and presented in 1866 to the Ducal 

 Museum in Brunswick, of which he had previously given a 

 preliminary notice. The species treated of are 80 in number, 

 on which many excellent critical remarks and comparisons 

 are given. The only species new to Celebes is Terekia cinerea, 

 but it is not quite certain that the specimen of it belongs to 

 this collection. Had the series been worked out at the time 

 of its arrival in Europe it is obvious that it would at that 

 epoch have contained many novelties since described from 

 other sources. 



4. Buttikofer on Birds from the Tenimber Islands. 



[On a Collection of Birds from the TenimLer Islands. By J. Biit- 

 tikofer. Notes Leyden Mus. viii. p. 58.] 



In 1883 Mr, Riedel, the Resident at Amboina, presented 

 to the Leyden Museum a collection of 35 birds from the 

 Tenimber or Timor-Laut group of islands. Mr, Biittikofer 

 refers them to 31 species and gives us some interesting notes 

 on them, Krythroniyias riedeli is a new species, and Ardea 

 picata and Fregata minor are new to the fauna. It seems 

 that the White Cockatoo of the Tenimber Islands, which 

 Sclater (P. Z. S. 1883, p, 197) referred to Cacatua sanguinea, 

 is rather smaller in size, and is exactly the same as the type 

 of C. gqffiui, Finsch, in the Leyden Museum, Erytltromyias 

 riedeli is nicely figured, and E.pyrrhonota of Timor is repre- 

 sented as a companion figure.
