INHABITING THE PHILIPPINE ARCHIPELAGO. 181 
Hodgs. (Ind. Rev. 1837, p. 326, “ Nipaul”),= D. balicassius (Linn.), apud Jerd., Blyth. 
Horsf. and Moore, etc., nec 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 afer, Lichtenst. M.A. A. H. Lichtenstein, in the Hamburg Catalogue’, p. 10, 
no. 99, identified with doubt what can only be the South-African Dicrurus musicus with 
Corvus afer, Linn. (1.¢. no. 12), founded on Pica senegalensis, Briss. (tom. cit. p. 40, 
no. 2). Lichtenstein did not create the title. Brisson’s bird is doubtless a Senegal 
Sturnine form, and was sent to Réaumur 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 /.c., and which therefore 
becomes the senior title for Dicrurus musicus, Vieillot. 
Oriolus furcatus, Gm. 8. N. i. p. 395, no. 52. A title given to the Jcterus cauda 
bifida, Brisson, Orn. ii. p. 105, no. 16, which in its turn was founded originally on the 
Turdus niger mexicanus, Seba, Thesaurus, i. p. 102, pl. 65. fig. 4. Clearly a Dicrurus 
(Buchanga), said by Wagler (Syst. Av. p. 364) to be Dicrurus caerulescens (Linn.), but 
which, from the crissum only being described as white, I believe to be Dierwrus 
leucopygialis, Blyth. 
81. * DicRURUS MIRABILIS. 
Dicrurus mirabilis, Walden & Layard, Ibis, 1872, p. 103, pl. 5, “ Negros.” 
Hab. 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. 8. 1836, p. 5; and Jard. Tlustr. pl. 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. 
* Catalogus rerum naturalium rarissimarum Hamburgi, 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. 
Lichtenstein, Rector 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 University of Kiel.
