the Genua Rectes. 437 



young of the black-headed ones, I accept the evidence of 

 Count Salvador! and Dr. Meyer, who have had very large 

 series at their disposal, although I do not consider the question 

 to be yet definitely settled. 



From the Astrolabe Mountains Mr. C. Hunstein sent two 

 males and a female of a Rectes. The female is R. brunnei- 

 ceps of D'Albertis and Salvadori, and the male is undescribed. 

 It may be diagnosed as follows : — 



Rectes meridionalis, sp. n. 



R. similis R. uropygiali, sed scapularibus dorso concoloribus 

 nee uigris, et uropygio tantum nigro distinguenda. 

 Long. tot. 10"0, alse 5*3, caudse 4*3. 



These specimens are doubtless the same as the three from 

 Naiabui referred to R. dichrous by Count Salvadori ; but I 

 shall not be surprised to learn that they are only really the 

 males of jR. brunneiceps. Time alone can prove this. 



The true R. dichrous also occurs in South-eastern New 

 Guinea, quite a series having been obtained by Mr. Forbes 

 in the Sogeri district of the Astrolabe range. Dr. Meyer 

 has a pair from Amberbaki, where the female is exactly 

 similar to the male, and we have in the British Museum a 

 nestling which is almost exactly like the adults, having a 

 black head and throat. The female has the wing 4*3 inches, 

 the male 4'2, and in Forbes's six specimens the wing varies 

 from 4'1 to 4*3 inches. The entire absence of black on the 

 rump and upper tail-coverts distinguishes R. dichrous. 



I quite agree that Rectes tibialis of my Catalogue is not 

 separable from R. uropyyiuUs, as Count Salvadori has already 

 determined. 



Rectes decipiens of Salvadori seems to be a large form of 

 R. dichrous, with the wing 5 inches ; but I do not see how the 

 distinction between this species and R. cirrhocephalus and 

 R. 7'ubiensis can be maintained, for they seem to run one into 

 the other. Thus a male collected at Dorey by Mr. Wallace 

 is exactly similar in the colour of the head to a female from 

 Rubi, and a male from Rubi is absolutely the same as a male 

 from Inviorage. 



In the same way Rectes analogus of Meyer, from the 

 Aru Islands, is only the young of R. aruensis. We have 

 several similar ones in the Museum, from the Aru Islands.
