In the preceding lists it will be seen that I have followed Dr. Finsch's 

 arrangement very closely, except in giving an additional species, P. corallinus. 

 I will now say a few words on this subject, and as regards P. tumultuosus, 

 of which Dr. Finsch was unable to examine specimens. 



First, as regards P. corallinus, as I have already had occasion to 

 remark, I cannot but consider this species perfectly distinct from 

 P. sordiclus of Venezuela. So far as I can tell from what Dr. Finsch says, 

 it would appear that, at the time when he wrote his description of Pionus 

 sordidus (Papag. ii. p. 452), he had never met with examples of the Venezuelan 

 bird. His descriptions and notes seem to apply entirely to P. corallimis. 



The true P. sordidus, of which I have a skin from Venezuela, collected 

 by Mr. Goering in 1868f, is immediately distinguishable from P. corallinus 

 by the whole back, nape, and wing-coverts being of a sordid yellowish olive- 

 colour with the edgings of the feathers lighter, instead of a uniform green 

 as in P. corallinus. The abdomen is nearly of the same colour, only rather
