LIST OF A SECOND COLLECTION OF BITJDS FKOM THE 

 NATUNA ISLANDS. 



By ERNST HARTERT. 



WHEN I gave (Novitates Zoologicae I. pp. 469 fl'.) tho first list of birds iVum 

 the Natnna Islands, I hoped Mr. Charles Hose, the well-known Borneau 

 explarer, would visit these islands in a different season, i.e. in s])rin<r: Lnt unfor- 

 tunately this could not be done, and Mr. Charles Hose's brother, with a well-trained 

 lot of Dayaks to shoot and to skin, went to the islands and stayed there from July 

 to October 1894, i.i: much the same season as Mr. Everett. Besides Bunguran, the 

 largest of the group of islands, the small ontlyiny; island of Pulu Laid, north of 

 Bunguran, and several unimportant little islets, were visited. 



In the following pages I give a complete list of the species sent. It will be 

 seen that the number of species known to inhabit the islands became much larger by 

 the present collection, but, althongh of considerable interest, it contained no new 

 forms, the few previously uudescribed forms found in the islands having been 

 formerly sent by Mr. Everett. At least one of the forms distinguished in my first 

 article (the Stachyris) became rather doubtful by this collection, and, owing to the 

 season, many birds were badly moulting at the time of the visit. 



A few birds only were sent from the outlying ishuid iif Tnlu Lant, and those 

 seem not different from the Bunguran birds ; but the mammals from Pulu Laut (a 

 Malayan name meaning " Island in the Sea," applied to many outlying islands) are 

 of considerable interest, and will be treated in a following article. 



The species now new to the Natuna list are marked with an asterisk (*). 



The same plan as before has been followed in working out this collection. (See 

 Vol. I. p. 469 ; see also the introductory remarks by the Hon. Walter Rothschild, 

 pp. 467, 468.) 



1. Cittocincla macrura (Gm.) (Nov. Zooi.. I. p. 469). 

 A number of males and females from Bunguran. The black bases of tlie 

 lateral rcctrices are olivious in all specimens, but they vary a little in extent. 



'■I. Phylloscopus borealis (Bias.) (Nov. Zool. I. p. 469). 

 Bunguran. 



3. Orthotomus atrigularis Tenim. (Nov. Zooi,. I. p. 469). 



A number lV(jm Bungnran and one from " Pulu Paudalc." 



The quite young birds have no rufous colour at all on the head. One adnlt 

 female shows partial albinism, the upper surface from tlie head to the riinip being 

 canary-yellow. 



4. Malacopterum cinereum bungurense llartcrt (Nov. Zom.. 1. p. 470). 



Only three specimens sent from Bunguran. One is a little darker on the head 

 and ujiper tail-coverts, thus merging into the usual form.
