Very much like P. trigeminus, having the lilac-purple abdominal 

 patch surrounded with saffron-colour, but has the pileum pale 

 lilac, nearly white ; bill greenish ; feet red.

Ptilopus quadrigeminus, Mryer, Ibis, 1890, p. 421 (Constantino Har- 

 bour) ; Salvad. Mem. R. Ac. Tor. (2) xlii. p. 51 (1841). 



Like P. geminus, Salvad., but the sides of head and throat grey, 

 the latter showing hardly a hue of yellowish in the middle ; pileum 

 a little brighter and without the purple stripe on the occiput in 

 front of the yellow band ; the yellowish brown of the belly is some- 

 what lighter, whereas the yellow of the under tail-coverts and 

 abdomen (or vent ?) is more intense. Wing 4-5 inches, tail 2-59, 

 bill 0-47, tarsus 0-59 {Meyer). 



I have not seen this species ; the only remark I can make con- 

 cerning it is that the want of the purple stripe on the occiput, in front 

 of the yellow band, is a sign of immaturity in the allied species. 



Hah. Constantine Harbour or its neighbourhood (Kubary), North- 

 eastern coast of New Guinea.
