Mr. Clark has tried to shew that a Parrot from Guadeloupe, 

 mentioned and insufficiently described by old authors (Du- 

 tertre, Hist. Gen. des Isles des Cristophie, de la Guadeloupe, 

 etc. p. 298, 1654; Labat, Nouv. Voy. ii. p. 214, 1742; 

 Briss. Orn. iv. p. 302, 1760; Buff. Hist. nat. Ois. vi. p. 233, 

 1779), is different from Deroptyus accipitrinus, with which 

 the supposed bird from Guadeloupe has been generally 

 identified. The obscure and contradictory descriptions given 

 by old authors make the identification of the Guadeloupe 

 bird hopeless.

Similar to D. accipitrinus from Cayenne and British 

 Guiana, but " somewhat larger and with the pileum not 

 hoary grey, but brown with hoary streaks and with the 

 lateral tail-feathers without the dull red spots at the bases 

 of the inner webs." (Salvad. I. c.) 



Hob. The Lower Amazon valley. 



In the ( Catalogue of Birds' I duly noticed the differences 

 between the specimens of this bird from Guiana and those 

 from Maranham and Sarayacu, and stated that the latter 

 probably belonged to a distinct form. Mr. Hellmayr, having 

 examined fresh specimens from Para and Villanova on the 

 Amazon, has confirmed the differences found by me and has 

 given a name to the Brazilian form. He is inclined to 

 believe that the new form is confined to the lower Amazon
