IlSTIABITlNa THE PHILIPPINE AECHIPELAGO. 181 



Hodgs. (Ind. Rev. 1837, p. 326, "Nipaul"),= D. balicassius (Linn.), apud Jerd., Blyth. 

 Horsf. and Moore, etc., nee Linn. 



The following titles have been regarded by some authors as belonging to the Luzon 

 species, although they have nothing to do with it : — 



Corvus qfer, Lichtenst. M. A. A. H. Lichtenstein, in the Hamburg Catalogue\ p. 10, 

 no. 99, identified with doubt what can only be the South -African i'tcrwrMS musicus yvith 

 Corvus afer, Linn. (I. c. no. 12), founded on Pica senegalensis, Briss. {torn. cit. p. 40, 

 no. 2). Lichtenstein did not create the title. Brisson's bird is doubtless a Senegal 

 Sturnine form, and was sent to Reaumur by Adanson. 



Corvus adsimilis, Bechstein, Latham's allgemeine Uebersicht der Vogel, ii. p. 562, 

 no. 47 (1791), ex M. A. A. H. Lichtenstein ; Kurze Uebersicht, p. 117, no. 44. A title 

 given by Bechstein to Corvus afer, Linn, apud Lichtenstein I. c, and which therefore 

 becomes the senior title for Dicrurus musicus, Vieillot. 



Oriolus furcatus, Gm. S. N. i. p. 395, no. 52. A title given to the Icterus Cauda 

 bifida, Brisson, Om. ii. p. 105, no. 16, which in its tiu-n was founded originally on the 

 Turdxis niger mexicnnus, Seba, Thesaurus, i. p. 102, pi. 65. fig. 4. Clearly a Dicrurus 

 {Buchanga), said by Wagler (Syst. Av. p. 364) to be Dicrurus ccemlescens (Linn.), but 

 which, from the crissum only being described as white, I believe to be Dicrurus 

 leucoj^ygialis, Blyth. 



81 . * DiCRUBUS MIRABILIS. 

 Dicrurus mirabilis, "Walden & Layard, Ibis, 1872, p. 103, pi. 5, "Negros." 



Hah. Negros (L. C. Layard, Meyer). 



Only differs from D. balicassius in having the lower breast, abdominal regions, flanks, 

 and under tail-coverts white instead of black. Dr. Meyer procured several examples in 

 Negros. 



In the ' Birds of India' (i. p. 438) it is stated, on Mr. Blyth's authority, that Edolius 

 rangoonensis, Gould (P. Z. S. 1836, p. 5 ; and Jard. Illustr. pi. xxxviii.), is a Philippine, 

 and not a Burmese species. It is not impossible that the genus Dissemurus is repre- 

 sented in the Philippines ; but E. rangoonensis, Gould, although apparently unknown 

 in Burma, seems to have been founded on an example of the Malaccan crestless 

 Dissemurus. 



' Catahgus rerum naturalium rarlssimarum Hamhurgi., d. xxi. October, 1793. An auction catalogue of 

 zoological specimens sold at Hamburg on the above date and following days, and drawn up by M. A. A. H. 

 Licbtenstein, Eector of the Johannis School. Many species are described, and new titles bestowed. The work 

 is rare, the only copy known to me being contained in the Library of the Tniversity of Eiel.
