Brazil). 

 ? Psittacula passerina Auct., part. 



Habitat. — Bahia district of eastern Brazil. 



Sp. char. — Similar to P. 2)asserina, but darker or purer green both 

 above and below; adult male with blue of rump, etc., rich ultramarine, 

 instead of cobalt, and hind-neck often tinged with blue. 



Adult male (type, No. 46723, Bahia; Mr. Middleton) : Above deep parrot- 

 green, or grass-green, duller and slightly tinged with bluish on nape; top 

 and sides of head vivid grass-green, inclining to emerald on auriculars 

 and becoming slightly more yellowish around base of bill; lower parts 

 emerald-green medially, more brownish green hiterally; lower back, 

 rump, secondaries (except tertials), shorter primaries, primary coverts, 

 alula, greater coverts, under wing-coverts, and axillars, rich ultramarine- 

 blue. Length (mounted specimen) about 4.25; wing 3.25, tail 1.70, 

 culmen .48. 



Adult female : Similar to the male, but without any blue ; length 

 (skin) about 4.50-5, wing 3.05-3.35, tail, 1.60-1.75, culmen .45-.48. 



The blue of the greater wing-coverts is lighter than that of the sec- 

 ondaries, the difference being sometimes very marked. 



Three adult males from Bahia (two in the Lawrence collection and 

 one in the collection of the Museum of Comparative Zoology, Cam- 

 bridge, Mass.) agree very closely in coloration with the one described 

 above. Length (skins) 4.50-5, wing 3.20-3.25, tail 1.60-1.70, culmen 

 .42-.48. One from Maceio Bay (No. 7252, Mus. Comp. Zool.) is similar 

 in coloration, and measures as follows: Length (skin) 4.60, wing 3.30, 

 tail 1.70, cuTmen .50. The bill is decidedly larger than in Bahia specimens, 

 as it is also in a female from the same locality, but I am unable to appre- 

 ciate any other diflereuces.
