614 DR. G. HARTLAUB ON A NEW PSITTACULA. [Juiie 16, 



North Brazil, not to be confounded with Ps. passerina, (3) Ps. 

 cyanopyga, from the island of Tres Marias, (4) Ps. coelestis, and (5) 

 Ps. conspicillala, — and after having searched most assiduously, but 

 without success, for a description in the systematical works, I think 

 that I am justified in describing my Psittacula as of a new species. 

 May I be allowed to name it after my friend Dr. W. Spengel, a 

 well-known zoologist and the able Director of the Bremen Museum. 



Psittacula spengeli, sp. nov. (Plate XXXVIII. fig, 1.) 



Minor; rostro pro mole niagno et valde robusto; Icete et dilute 

 psittacino-viridis : pileo Icetius et purius tincto ; (/astrceo 

 nonnihil in Jiavidum vergente ; tergo infimo, uropygio et 

 supracaudalibus dilute azureis ; subalaribus prope marginem 

 internum alee ex azureo-malachitaeeis, dein intense cobaltino- 

 cyaneis : tectricibus remigum sec. ord. uropygio concoloribus ; 

 alula spuria nigro-ccerutescente ; scapulmnbus dorso concoloribus ; 

 rectricum pure et dilute viridium pogoniis internis subvirescenti- 

 flavis, mediis totis viridibus ; subcaudalibus ?iitide et dilutissime 

 viridibus ; rosti'o pallido ; pedibus incarnatis. Long. tot. circa 

 107 millim. ; alee 81 millim. ; caud. 30 millim. 

 The colour of the upper parts is a light parrot-green, finer and 

 purer on the crown and the sides of tlie head ; underparts somewhat 

 lighter with a faint yellowish shade ; rump and upper tail-coverts 

 of &fine light turquoise-blue (the same as in Ps. cyanopyga) ; greater 

 wing-coverts of the ^ame colour ; primaries black on the inner and 

 green on the outer webs ; under wing-coverts near the margin of the 

 wing of the same light turquoise-blue, but nearer the body of a fine 

 blue ; tail-feathers light green, the inner webs of the lateral rectrices 

 yellow, with an indistinct greenish shade ; under tail-coverts of a 

 very light yellowish-green ; beak very large, whitish ; feet flesh- 

 coloured. 



Psittacula spengeli resembles P. cyanopyga in the turquoise- 

 colour of the rump ; but differs from it in its smaller size, in the much 

 larger beak, in the cobalt-blue spot on the inner wing-coverts, and 

 in the yellow inner webs of the rectrices. In Psittacula cyanochlora, 

 Natt. {passerina, c? ji"-, Finsch), the inner wing-coverts are very 

 much like those of Ps. spengeli ; but the colour of the rump is, as in 

 the former species, a brilliant emerald-green, and the inner webs of 

 the rectrices are not yellow but green with yellowish margins. 

 Psittacula cyanochlora is altogether a larger bird with a much 

 smaller beak. The cobalt-blue colour of some of the tectrices of 

 the primaries, so apparent in Ps. cyanochlora, is entirely wanting in 

 Ps. spengeli. 



So far as I know, Psittacula spengeli is the only member of 

 tins lovely little group in which the colour of the inner wing-coverts 

 repeats that of Ps. passerina &c., and tlie colour of the rump that of 

 Ps. cyanopyga. 



I take this opportunity of sending for exhibition a typical specimen 

 of Ps. cyanochlora, Natt. MS., which, as already observed, has been
