considered by Dr. Finsch as the youug male of Ps. passerina, but 

 which I beheve to be a distinct species. It may be described as 

 follows : — 



PSITTACULA CYANOCHLORA. (Plate XXXVIII. fig. 2.) 



c? . Supra psittacino-vh'idis, nonnihil obscurius adumbrata ; capitis 

 lateribus et gastrceo toto dilutius et subflavescenti-viridibus ; 

 tergo, uropygio et supracaudalibus pulchre smaragdino-viri- 

 dibns ; rectricibus viridibus, pogoniis internis marginem versus 

 fiavicantihus ; alarum tectricibus minoribus dorso concoloribus 

 majoribus (remig. sec. ord.) cyanescentibus, in malachitaceum ver- 

 gentibus, nonnullis subelongatis et angusfatis, cobaltino-caruleis ; 

 subalaribus pulchre et extense cobaltinis ; margine interna atari 

 e malachitaceo viridi ; rostro toto pallido ; pedibus incarnatis : 

 crassitie Ps. passerinae. 

 Hab. Rio Brancho {Natterer). 



There is a young male Ps. passerina in the Bremen Collection which 

 resembles Ps. cyanochlora in most respects. But there are some 

 differences, and amongst them there is one which I consider to be 

 rather important. In this " young male " of Caracas the cobalt-blue 

 spot on the subalares is very small and has evidently not yet reached 

 its full extension. In cyanochlora you will observe that the cobalt- 

 blue of the subalares has the greatest possible extension, just as in 

 the old male of passerina. Now this is very curious, and very much 

 in favour of my opinion . 



The colour of the tectric. major, is very similar in the Caracas bird 

 and in Ps. cyanochlora, but it is brighter in the latter. The curious 

 one or two narrow elongated dark-blue feathers are to be found in 

 both birds. 



The emerald-green colour of the rump is also the same in both 

 birds, it being only a little brighter in Ps. cyanochlora. 



The green colour of the upper parts is much lighter and purer in 

 the Caracas bird, and the sides of the head and the whole uuder- 

 parts are of a different green, liner, more emerald, and less 

 ellowish than in Ps. cyanochlora.

The ' Marchesa,' on leaving the Moluccas, proceeded to the islands 

 lying off the north-west coast of New Gruinea. Batanta and 

 Waigiou were first visited ; and from the former, in the neighbourhood 

 of a fine bay discovered at the east end (which was roughly surveyed,
