 covering the cere, so that the nostrils are coucealed by them.

Head of Mascarimis duboisi. 



The lores also are fully feathered, and there is only a narrow 

 circumorbital ring left naked. In all the species of Coi'a- 

 copsis the cere is large and conspicuous, being quite bare of 

 feathers, there is a large nude circumorbital ring, and, par- 

 ticularly in C. vasa, the lores are sparingly feathered f- In 

 Psittacus the cere and nostrils are equally conspicuous, and 

 the lores and cheeks even more sparingly feathered. 



The feet (figs. 2, 3) differ from those of Coracopsis in their 

 shorter and thicker tarso-metatarsi and shorter nails. Prof. 

 Alphonse Milne-Edwards extracted the lower mandible from 

 the stuffed specimen in the gallery of the Museum, and has 

 figured it in his article on the various forms of that bone in 

 the different groups of Parrots:}:. He says that it difiers 



* The figures, both of D'Aubenton (PI. Enl. 35) and Levaillant (Hist. 

 Nat. Perr. ii. pi. 139 [1805]), show a red beak, narrow naked orbital ring, 

 and feathered lores and cere. Hahn's figure does the same ; but Wagler 

 says the cere was uncovered (cf. Finsch, Pap. ii. p. 297).
