NOTE ON THE GENERIC NAME BOLBORHYNCHUS BONAPARTE. 



As originally proposed in Comptes Rendus, XLIV, 1857, p. 596, this 

 name is a pure nomen nudum, and recent authors have turned to Souance, 

 Icon. Perroquets, 1857, for the purpose of determining the type species, 

 which has been fixed as Arara aymara D'Orbigny. The genus has been 

 recently subdivided by Mr. Ridgway,* who has retained the name 

 Bolborhynchus (by inference) for aymara, and created three additional 

 genera, Grammopsiitaca (type, Psittacula lineola Cassin), Nannopsittaca 

 (type, Brotogerys panychlorus Salvin and Godman) and Psilopsiagon 

 (type, Trichoglossus aurifrons Wagler). 



Unfortunately for nomenclature, Bonaparte introduced some additional 

 matter in the author's separately paged reprint t of this paper, which is, 

 in fact, a combination of two papers from the Comptes Rendus and has 

 priority over Souance's work. Here we find (p. 6) Bolborhynchus as a 

 valid name, with two ostensible species, Myiopsitta tigrina Honance,* and 

 Myiopsitta catharina Bonaparte, both now synonymized under Bolbor- 

 hynchus lineolus (Cassin). The species aymara is not mentioned, hence 

 the type must become one of the two forms noted above. I accordingly 

 designate Myiopsitta catharina Bonaparte ( = Psittacula lineola Cassin ) 

 as type, since M. tigrina, said to be from Venezuela, may prove to be 

 difi"erent. It follows that Grammopsittaca Ridgway is a pure synonym 

 of Bolborhynchus, and that aymara is without a genus. For this species 

 I propose the generic ■ term Amoropsittaca § (type, Arara aymara 

 D'Orbigny). — Chas. W. Richmond. 



NOTE ON CHLOROSTILBON PURUENSIS. 



In these Proceedings, || I described a hummingbird as Chlorostilbon 

 puruensis. Shortly after the description was published I became con- 

 vinced that I had placed the bird in the wrong genus. I was led astray 

 by its resemblance to Chlorostibon prasinus, an aberrant member of the 

 genus Chlorostilbon. My bird really belongs to the genus Chlorestes and 

 is close to Chlorestes cseruleus, but not quite the same. The chin is not 

 quite so blue and the bill is longer. Seven adult males of Chlorestes 

 c. aeruleus from Bahia and the lower Amazon have the culmen, 15.5-17 

 (1().5) against 18 and 19.5 for my C. puruensis. In view of the above 

 facts, the combination Chlorestes cseruleus puruensis will better express 

 the relationship of the bird described by me. — /. H. Riley.

tThe reprint is entitled "Remarques k propos des Observations de M. Emile Blan- 

 chard sur les Caracteres ost6ologiques Chez les Oiseaux de la famille des Psittaeides, et 

 Tableau des genres de Perroquets disposes en series parallfeles," pp. 1-9; published in 

 March, 1857. It may be added that the genera Primolius and Ptiloscle.ra are valid from 

 this reprint (jiom/na nwda in the original paper), and the name Ognorhynchus occurs 

 for the first time. The latter will replace Qnathositlaca Cabanis, 1864 (= 1865).
