68. BiittiJcofer on Birds from Nias. 



[On a Collection of Birds from Nias. By Dr. J. Biittiliofer. Notes 

 Leyden Mus. xviii. p. 161.] 



From the collections of Rosenberg, Modigliaui as reported 

 on by Count Salvador!^ and of Claine as described by 

 Dr. Oustalet, together with additions made by Count Ber- 

 lepsch from sjaecimens received by him from Mr. W. Thomas, 

 we know of the existence of 104 species of birds in the Malay 

 Island of Nias, near Sumatra. A splendid series recently 

 obtained in Nias by Mr. J. Z. Kannegieter^ ai:d received at 

 the Leyden Museum, enables Dr. Biittikofer to make 24 

 additions to the list, thus bringing up the whole number of 

 the birds of Nias now known to 128. Four of these are 

 new to science, and are named Keivpa minor, Chrysophleyma 

 niasense, Artamides kannegieteri, and Carpophaga vandepolli. 

 Amongst the winter visitors to Nias are enumerated such 

 well-known northern species as Geocichia sibij'ica, Phyllo- 

 scopus boreulis, and Motacilla metanope.

[On a probably new Species of Newtonia from Madagascar. By Dr. J. 

 Biittikofer. Notes Leyden Mus. xviii. p. 199.] 



Newtonia olivacea is a second species of the genus, closely 

 allied to N. brunneicauda, but undoubtedly different. Two 

 specimens in the Leyden Museum were obtained at Savary, 

 N.E. Madagascar, by Audebcrt in 1878. 



70. Chapman on the Birds of Yucatan. 



[Notes on Birds observed in Yucatan. By Frank M. CLapruan. Bull. 

 Amer. Mus. Nat. Hist. viii. p. 271.] 



The birds of Yucatan are already well known to science 

 principally from collections made during the past 18 years 

 by Dr. Gaumer^ who is residing at Izamal, and the results 

 of whose investigations have been mostly incorporated in 

 the "Aves" of the ' Biologia Centrali- Americana.' But 

 Mr. Chapman has done a good piece of work in putting 

 together his field-notes on 74 species which he met with at
