Lcugth (skin) 5; wiug 3.25, tail 1.80 culineu .47, gonys .30, width of 

 upper mandible at base .32, tarsus .47; inner toe .50 



Two additional adult males are exactly like the ty[)e, as described 

 above, in coloration, and nieasnre as follows : Length (skins) 4.70-4.85, 

 wing 3.15-3..)0, tail 1.70-1.75, culmen (of one specimen, the nj)per man- 

 dible of the other being mutilated) .45, depth of bill at base .48, width 

 .28, tarsus .45. 



An adult male from Santarem in the collection of the Museum of Com- 

 parative Zoology, Cambridge, Mass., agrees minutely in coloration with 

 the Diamantina specimens. It measures as follows: Wing 3, tail 

 1.00, culmen .45, width of ui)per maiulible at base .32, tarsu:; .4J, outer 

 toe .45. 



Two other adult females likewise agree with the one described above, 

 the forehead of one, however (perhaps a younger bird), being less ex 

 tensively yellow. They measure as follows : Length (skins) about 4.50- 

 5; wing 3.10-3.15, tail 1.G5-1.70, culmen .45-.47. 



UNDETERMINED NAMES. 



T am unable to identify the following with any species of this genus 

 known to me : 



1. Psittacus capeiisis MOll. 



IVillaciis capeims Mull., S. N. Siippl., 1767, 80 (l)aMe(l on Petit Pcrruche, du Cap de Bon. 



Enpcrance, Buff. PI. Enl. 4.>5, fig. 1. 

 PsiltacHS cfianopterm BODD., Tabl. P. E., 178:J, 27 (same basis). 



This bird has very generally been identified with the Guiana species 

 (P. guianensu Swains.), but without the slightest reason, that 1 can see. 

 The figure in PI. Enl. itself is wholly undeterminable, with our present 

 knowledge, and if really taken from an American specimen may just 

 as well be P. passerina without blue ou the rump as any other; in fact, 

 the figure agrees much better with the latter than with any idumage of 

 P. guia)iensis. 



2. Psittacus leucophthalmus Scopoli. 



Pailtacm lemophlhalmua ScOP., Delic. Flor. et Faiiu., 1786, 87 (based on Petite Pcrruche 

 de Vile de Lu^on, Seconde espece, Sonnini, Voy. a la Nonv. Guiude, 1766, 76, pi. 

 38, upper fig. ). 



PaiHacus siritplcx Kuhl, Consp. Psitt., 1820, 66 (same basis). 



Although this has usually been referred to P. pa.sscrinnSj 1 can see 

 no reason whatever for considering it as an American bird at all. It is 

 said to have come from Lu9on, one of the Philippine Islands. 



3. Psittacus St. thoniae Kuhl. 



Psittacus St. thomce Kuhl, Consp. Psitt., 1820, .^)8 (island of St. Thomas).

 bill in the male yellow, in the female greenish yellow ; tail underneath 

 pale yellowish green, towards the tip more of a brownish yellow ; the
