Ridgway {I.e.) states that he has seen specimens from Para of trne P. p. 

 passerina, but as no Psittacula has been found recently in this district, the locality 

 requires confirmation. 



Of P. p. vivida I have examined fifty specimens in the Mnsenms of Triug, 

 Vienna, Berlepsch and Munich : from Bahia, Rio, S. Paulo, Santa Catharina and 

 Paraguay. 



c. P. passerina crassirostris Tacz. 



Hab. Northern Peru : Yurimagnas (Stolzniann), Samiria and Nauta(Hanxwell). 

 N.W. Brazil : Teffe, on the Rio SolimOes (Hofl'manus). 



c? ad. Differs from P. p. passerina and P. p. vivida by its larger and higher 

 bill, shorter wings, and by having the rump, axillaries, and under wing-coverts 

 rather lighter blue, more " ultramarine blue " (Ridgw. Nomencl. ix. 9) instead of 

 smalt blue (Ridgw. ix. 8). 



? ad. Characters given above. 



Three S <S from Samiria and Nauta, Pern, measure as follows : wing 80J, 

 78, 77 ; tail 38, 37, 38 mm. 



d. P. delieiosa Ridgw. 



Hab. Lower Amazons : Santarem (Riker, Garbe) ; Obidos (Hoffmanns). 



d ad. Easily knowu from the three preceding forms by having the lower back 

 and rump light emerald green, tinged with delicate nile-blne on the anterior 

 portion. Upper tail-coverts much more yellowish green ; greater upper wing- 

 coverts delicate nile-blue, passing into ultramarine blue along the shaft (instead 

 of being uniform ultramarine). Axillaries and under wing-coverts considerably 

 darker, intense hyacinth-blue. Secondaries ultramarine blue, narrowly edged 

 with light green on the apical half of the outer web (as in P. p. passerina and 

 P. p. vivida). Wing 79 ; tail 40 mm. 



¥ ad. (No. 3418 Mus. Paulista, Santarem, January 1903. E. Garbe coll.). 

 Differs from the ¥ ¥ of P. p. vivida only by its smaller size. Wing 77 ; 

 tail 39 mm. 



Material : 1 S ad., Obidos ; 1 ? , Santarem. For the loan of the ? I am 

 much indebted to Prof. H. von Ihering, of S. Panlo. 



e. P. guianensis gaianensis (Sws.). 



Agajmmis guianensis Swainson, Anim. in Menag. p. 320 (1838 — Demarara). 



Hab. British Guiana : Demerara (Swainson), Annai (Whitely) ; Surinam : 

 near Paramaribo (Chunkoo coll.). 



3 ad. Like P. delieiosa, with the axillaries and under wing-coverts intense 

 hyacinth-blue, but differing at a glance by haviug the lower back and rump pure 

 emerald green (without any nile-blue tinge), the greater upper wing-coverts glaucous 

 green, and the secondaries dull bluish green (instead of bright ultramarine blue). 



Wing 78—83; tail 41—43 mm. 



¥ ad. Not distinguishable from that of P. delieiosa. 



Wing 78—80 ; tail 39— 40A mm. 



Material : 3 S cf ad., 1 $ jnv., 2 ¥ ¥ from Surinam in the Tring Museum ; 

 1 $ ad., Auuai, Brit. Guiana (H. H. Whitely, jr., coll.), in British Museum. 



The $ ad. from British Guiana has, like those from Surinam, all the under 

 wing-coverts and axillaries uniform hyacinth blue, and it seems to me, therefore, 

 extremely doubtful whether the locality of the Esseqnibo specimen in the American
