Appendices 13 5 
Apterornis ccerulescens , De Selys-Longchamps, Revue Zoolog. 
Oct. 1848, p. 3 [ potius , p. 294]. 
Cyanornis erythrorhyncha, Bonaparte. Conspectus Avium , ii. 
p. 3 ( except synon. Didus broeckii). 
Size of a heavy Goose or Turkey. Feet like a Hen’s. Colour 
blue. Bill and feet red. Does not fly, but runs extraordinarily 
fast. 
Hab. Bourbon [Reunion.] 
Only observed by D. B. [Du Bois] in 1669 [between 1669 and 
1672]; never seen since, and apparently extirpated. [Seen by 
Governor Villers in 1701-1709]. Seems with Notornis mantelli to 
represent the Hen-type among the Porphyrios. 
APPENDIX C. 
Professor Alfred Newton and Sir Edward Newton on the Psittaci 
of the Mascarene Islands. 
Extract from the Ibis for July 1876, pp. 280-289. 
Unusual interest attaches itself to the members of the Order 
Psittaci indigenous to the Mascarene Islands, from the fact that, 
while all of them are species peculiar thereto, the great majority 
have either already become extinct within the last two hundred 
years or must be regarded as expiring. . . . 
The Mauritian fauna once included two Parrots, the large 
species described by Professor Owen . . . Lophopsittacus mauri- 
tianus. . . . There is no doubt that this bird has long been 
extinct. A smaller species of Parrot—commonly known as Palce- 
ornis eques —still survives in Mauritius. . . . 
Here it is to be remarked that the specific term eques con¬ 
ferred by Boddaert on the subject figured in the ‘Planches 
Enluminees ’ (No. 215) [Reproduced p. xxviii], properly belongs 
to the Parrakeet of Reunion—the bird there represented being 
called ‘ Perruche de Vile de Bourbon ,’ whence De Buffon (. Hist. 
Nat. Ois. vi. p. 144) expressly says it was brought, identifying it 
also with the ‘ Perruche a collier de lisle de Bourbon ’ of Brisson 
(Orn. iv. p. 328, pi. xxvii. fig. 1), who likewise states that it is 
found there. It now no longer inhabits Reunion, and whether 
a specimen from that locality anywhere exists is not known to us.
