6 ON A COLLECTION OF BIRDS 



tra. As Dr. Klaesi made his collections during the win- 

 ter , he obtained several migratory species , some of which 

 have also been collected by Mr. Bock, who visited the 

 same country, though only during the first winter months. 

 As the following list will sufficiently show the impor- 

 tance of this collection, I do not find it necessary to spend 

 much space for an explanation of the most interesting 

 species. I only call attention to the curious fact that Bec- 

 cari, though his collection was considerably smaller than 

 tliat of Dr. Klaesi, obtained 24 new species, while the 

 collection of the latter contains only one, which I am 

 much pleased to dedicate to its discoverer. Though undoubt- 

 edly many more species are still to be found in that vast 

 Island, there will hardly any place be found to produce 

 as many new ones as the country of Mount Singalang of- 

 fered to Beccari. The following species are here , as far 

 as I know, for the first time recorded as occurring in 

 Sumatra : 



Chrysoccyx maculatus (Gm.). 

 Serilophus lunatus Gould, 

 Buchanga stigmatops Sharpe. 

 Micropus melanoleucus (Eyt.). 

 Pitta cucullata Hartl. 

 Myioplioneus Jlavirostris (Horsf.). 

 Ortygometra cinerea (Hartl.). 

 Before I conclude these introductory lines, I have to 

 offer Dr. Klaesi's thanks to the gentlemen who , as much 

 as possible , facilitated his task. They are : Prof. Askenasy 

 at Heidelberg, who kindly furnished his scientific outfit, 

 Mr. J. L. L. van Leeuwen, Assistant Resident at Pria- 

 man, Mr. G. van Haren Karspel, Ass. Res. at Solok, 

 Mr. de Lannoy, Comptroller at Moeara Laboe , Mr. L.
