340 Mr. J. Gould on a new Species of the Family Pittidse. 



Lemur macaco presents three distinct varieties, which gra- 

 dually pass into each other. 1. Lemur macaco, Linn. White, 

 with the shoulders and front of the thighs black ; the size of 

 the black patches varies in different individuals : when they 

 cover the greater part of the body, it is L. suhcinctus of A. 

 Smith ; and when they unite together, abolishing the white, 

 they are Lemur niger. 2. White, yellow, or red ; the shoul- 

 ders and front of the thighs like the rest of the back. The red 

 variety is called L. rufus by Geoffroy. The 3rd variety is 

 described as pure white ; but this we have not got. 



I believe the variously coloui'ed specimens are all males, 

 showing a great mutability in tliat sex. On the other hand, 

 all the females that I have hithei-to seen are of one colour, 

 brown, with white whiskers — Lemur leucomystax, Bartlett. 



XLIII. — Description of a new Species of the Family Pittida2, 

 By John Gould, F.R.S. &c: 



Pitta [PhoBnicocichla) arquata, Gould. 



Forehead, lores, and throat reddish buif ; crown, nape, and 

 breast rich rusty red ; over (but posterior to) the eye a lovely 

 stripe of blue, as in Pitta gran-atina ; a broken tooth-like bar 

 of the same beautiful hue across the breast, separating the 

 rich rusty red of the chest from the deep scarlet of the abdo- 

 men ; upper surface of the body and scapularies brownish 

 olive-green ; primaries and secondaries brown, tinged witli 

 green ; the secondaries are also tipped with splendid blue, but 

 not so conspicuously as in P. granatina ; tail blue, tinged with 

 olive ; legs and bill black. 



Total length 6 inches ; bill 1, wing 3^, tail 1^, tarsi 1|. 



Hah. Borneo. 



Remark. Tliis new species is somewhat allied to the Pitta 

 granatina of Temminck and the Pitta concinna of Eyton. If 

 there be any difference in size, it is perhaps a trifle smaller 

 than either of those species, but is at once distinguished from 

 both by its very remarkable colouring, which in some respects 

 resembles that of tlie Pitta erythrogastra of Temminck. 

 The specimen above described is sui:)posed, with some pro- 

 bability, to be a female; if so, the male, when discovered, 

 will prove to be a still more lovely bird.
