unfortunately lost his life from blackwater-fevcr in Northern 

 Rhodesia in February last at the early age of thirty-three. 

 Mr. Marais is stated to have been an " ardent, indefatigable, 

 and capable " ornithologist, and was on a collecting - 

 expedition at the time of his death. He was at one time 

 employed in the Forest Department at Knysna, and was the 

 discoverer of the Bush-Shrike {Laniarius maraisi) named 

 after him by Mr. W. L. Sclater (' Ibis/ 1901, p. 183). 



99. Kollibay on the Paleearctic Swifts. 

 [Diepaliiarktischen Apodiden. Von Paul Kollibay. J. f. 0., April 1905.] 



The discovery by the author of a new " subspecies " of 

 Swift on the Dalmatian Island of Curzola, which has been 

 named Apus apus kollibayi by Tschusi zu Schmidhoffen 

 (cf. Ornith. Jahrb. xiii. p. 234), has induced him to examine 

 a considerable series of European Swifts in his own collection 

 and in those of his friends and correspondents. In the first 

 place, Herr Kollibay maintains that the pale form of Cypselus 

 apus named C.pallidus by Shelley (but which Herr Kollibay 

 calls by Brehm's name murinus) is a perfectly distinct species, 

 and embraces (as suggested by Hartert) two subspecies — 

 C. murinus typicus and C. m. brehmorum. In the second 

 place, after studying many specimens from Dalmatia he 

 declares that the separation of Cypselus kollibayi as a distinct 

 subspecies of C. apus is fully justified. Moreover, after 

 examining the series of Tunisian Swifts in the collection of 

 the late Carlo von Erlanger, he comes to the conclusion that 

 the Tunisian form also belongs to a distinct subspecies, which 

 he names Apus apus carlo (!). 



100. Madardsz on a new Bradypterus. 



[Ueber eine neue Bradypterus-Axt. Von Dr. Julius v. Madarasz. 

 Ann. Mus. Nat. Hung. iii. p. 113 (1905).] 



The National Museum of Hungary has received, in a collec- 

 tion transmitted by Koloman Katona from Kiboscho, in German 

 East Africa, an example of a new species of Bradypterus, 

 which is described under the name B. marus. It is most 

 nearly allied to B. alfredi Hartl. and B. barratti Sharpe.
