The Marquis of Tweeddale on the 
D. andamanensis. The difference in the colouring of the 
gloss/^ alluded to by Mr. Sharpe^ is not observable in the 
large series from both localities to which I have access. 
D. andamanensis is almost a typical Buchanga. It has all 
the habits of the continental species {teste Davison, Str. F. 
1874, p. 211); and the tail is deeply forked, as in the common 
King-Crow. A few of the erect frontal plumes being some¬ 
what lengthened and denuded of their webs can scarcely con¬ 
stitute a generic character; and this is not relied on by Mr. 
Sharpe; while the only differentiating generic character given 
by him seems to be still less distinctive^ namely outer tail- 
feathers recurved at tip.’^ Indeed, if a character at all, it is 
a family characteristic; for in all the Dicruridse there is a 
marked inclination in the outer pair of rectrices, when pro¬ 
duced, to recurve inwards. 
Dissemuroides edoliiformis. —For this species Mr. Sharpe 
has rejected Vieillot’s title of lophorhinus, which was adopted 
many years ago by Sundevall, and has been in general use ever 
since, although he admits Le Vaillant^s plate of Le Drongup 
(Ois. d^Afr. 173) to represent Blyth’s species, and on this 
plate and description Vieillot founded his title*. On the 
other hand, Mr. Sharpe makes VieilloFs title {lophorhinus) 
a synonym of D. forficatus, a species named cristatus by 
Vieillot, from another of Le VaillanFs plates {t. c. 166). 
Le Vaillant, in his account of Le shows in what 
manner it differs from Le Drongo {—D, forficatus (L.) =Z). 
cristatus j Vieill.), and mentions its larger dimensions and the 
shortness of the frontal crest as being points of difference. 
The large size, the small frontal crest, and the absence of, 
rackets make the identification of D. lophorhinus with this 
peculiar Ceylonese species a matter of certainty. And an ex- 
^ Vieillot gave (N. D. d’H. N. vol. ix.) Latin titles to all the nine species 
of Dicruri figured and described by Le Vaillant (Ois. d’Afr. iv.); but tbe 
number of tbe plate on wbicb Le Drongup is figured is tbe only one be does! 
not quote. It is manifest by tbe context that Vieillot merely reproduced ; 
Le Vaillant’s descriptive words; indeed be uses Le Vaillant’s very words; I 
and under tbe word Drongup {t.c. p. 589) tbe reader is referred to Le\ 
Drongo drongup, V.=Z). lophorhinus. Elsewhere and later (Enc. Method.] 
p. 752) Vieillot quoted Le Vaillant’s plate.
