After examination of all the described species except melanotis and 

 pyrrhops (of which, however, there is an apparently excellent plate — PL IX, 

 Cat. B. M.), I agree with Mr. Ridgway (cf. Proc. Biol. Soc. Wash., 1912, 

 p. 100) that Pionopsitta with pileatiis as the type, is monotypic. The re- 

 maining species (except melanotis) I allot generically as follows : 



Eucinetm Rchw. (J. f. O., 1881 p. 353, Type Psittacus caica Lath.) 



1. Eucinetus caica (Lath). 



2. " hmmatotis (Scl. & Salv.) 



3. " coccineicollaris (Lawr.) 



4. " barrabandi (Kuhl) 



5. " pulchra (Berl.) 



Pyrilia Bp. (Naumania, 1856, Type Psittacula pyrilia Bp.) 



1. Pyrilia pyrilia (Bp.) 

 Hapalopsittaca Ridgw. (Proc. Biol. Soc. Wash., 1912, p. 100, Type 

 Psittacus amazoninus Des Murs). 



1. Hapalopsittaca amazonina (Des Murs) 



2. " pyrrhops (Salv.) 



3. " fuertesi (Chapm.) 



(879) Pyrilia pyrilia (Bonap.). 



Psittacula pyriliaBoNAP., Compt Rend., XXXVII, 1853, p. 807 ("New Granada" 

 = Rio Hacha e. of Santa Marta, vide Scl. & Salv., Ibis, 1871, p. 381). 



Caica pyrilia Wtatt, Ibis, 1871, p. 381 (Canta; San Nicolas; Paturia); Scl. & 

 Salv., P. Z. S., 1879, p. 538 (Remedios). 



Inhabits the humid Tropical Zone of the Atrato, lower Cauca, and 

 Magdalena Valleys and evidently ranges upward to at least 9000 feet. 



This species is obviously not congeneric with Pionopsitta pileata, nor 

 can I refer it to either Eucinetus or Hapalopsittaca. Its bare orbital and 

 loral region and the character of the skin about the base of the bill do not 

 appear to be shared by any species of these genera.

(890) Pionites melanocephala pallidas {Bert.). 

 Caica melanocephala pallida Bebl., J. f. O., 1889, p. 317 (Yurimaguas, Peru). 



A pair from Amazonian Colombia agrees with one from eastern Ecuador, 

 and differs from lower Orinoco examples in having the flanks, etc. yellow.
