REPORT ON ZOOLOGY, MDCCOXLH : 
Hilaire, it is a doubtful matter to publish others, as the great libraries 
have no need of such a work, and will delay the purchase until con- 
vinced, that after the publication of the first number, it is not given up, 
as happens in so many cases. Should science need such an undertaking, 
the author (at whose command, indeed, must stand the whole ornitho- 
logical literature of this family, and a great collection), promises to give 
a critical description of all the species hitherto known, with plates of 
those which have not been previously represented. 
Riippell, in the Mus. Senckenb. iii. p. 125, has made known to us two 
new species of Parrots : 1. Psittacus {Piomis) rufiventris ; in size and 
form of tail resembling the Ps. senegalus, and also approaching it in 
the distribution of the principal colours, but having a much stronger 
bill : from Schoa : 2. Ps. (Pionus) Ji.avifrons ; about l-6th larger than 
Ps. Meyeri ; fore-part of head and region of eyes beautiful citron yellow ; 
the rest of plumage difierent shades of green ; from the Abyssinian 
province of Godjam. 
Psittacus [Amazona) au,ro~palliatus of Realejo, Arara erythrofrons 
of Valdivia, Ps. (Catca) chrysopogon of San-Carlos, and Ps. (Aratinga) 
ehu/rnirostrum of Acapulco, have been described by Lesson in the Rev. 
Zool. p. 135. 
The following species are represented in the new parts of Gould : — 
Nymphicus novce hollandim (part 7) ; Apromyctus scapulatus, Bechst., 
and erythropterus, Gm. (part 8) ; Trichoglossus Swainsonii, Jard,, ruhri- 
torquis, Vig., and versicolor., Vig. (part 9). 
Amphiboi.^. — R iippell has made known, in the Mns. Senck. 
iii. p. 127, two new species of CMz<btMs^ from the southern 
provinces of Abyssinia. 
1. Ch. per sonata ; regione ophthalmica, genis, mento et gula pennis 
denudatis, pileo crista plicatili plumis laxis elongatis colore murino ; 
nucha, regione parotica juguloque albidis, jugulo et pectore viridi- 
glaucis, abdomine et tibiis rufocervinis, auchenio, dorso et alls caesio- 
umbrinis, rectricibus olivaceis ; cauda elongata, subrotundata, supra 
cinerea, infra luteo-virente ; 19" : 2. Ch. leucogaster, pileo, crista plica- 
tili, plumis apice trimcatis ; capite, gutture, collo, cervice, dorso et 
alls ex caesio-umbrinis ; tectricibus mediis nigro-marginatis, remigibus 
dimidio basali albis, apicali umbrino-nigris ; cauda subrotundata, nigra, 
fascia lata alba transversa, rectricibus 2, intermediis ex caesio-umbrinis,
