AVIFAUNA OF LAYSAN, ETC. 



and more orange below. This may partly be clue to tlie remote date of their capture and 

 exposure to light, or they may be a little less adult. Their wings are 22G to 2*3 inches, 

 and their other measurements are the same as those of the type of L. wohtenholmei. 



Some specimens of L. rufa no doubt exist in Philadelphia, U.S.A., for one of Mr. Townsend's 

 specimens is now in the Museum at Liverpool. 



There is one immature male in the Berlin Museum, also from Oahu, which is coloured 

 thus : — Above greenish olive, brighter on the rump and upper tail-coverts, strongly washed 

 with orange on the head and occiput. Below orange, washed with deep orange-brown on 

 the throat and breast and with olive on the flanks. Size similar to that of the adult male. 



Another young male is in Vienna. 



An immature male in the Liverpool Museum, which was received there in 1838 " from 

 Mr. Townsencl per Mr. Audubon," is above of a deep rufous brown with some blackish 

 edges to the feathers, below very pale brownish rufous with some orange (new) feathers. 

 The wing is 2 3 inches long. 



There are females in the Museums of Berlin, Vienna, and Count Berlepsch. They agree 

 in colour with the females of Loxops coccinea, but they have no orange wash across the 

 breast. They are above olive greenish, brighter on the rump and upper tail-coverts and 

 on the edges of the wings and tail. Sides of head and entire underparts dull yellowish, 

 washed with olive along the sides of the body; quills brown, bordered with greenish, tail 

 similar. Wing 2*2 and 2*18 inches, tail 1*6. 



The Berlin specimens bear the Museum numbers 827, 828, and 829 ; the Berlepsch 

 specimens 1414 and 1415. 



This bird is distinguished from Loxops coccinea by the much more brownish colour of 

 the male and the smaller size ; and the female (if those known to me are perfectly adult) by 

 the colour of the breast and forehead, the latter not being lighter than the crown. It is 

 likewise easily distinguished from Loxops ochracca by the much more rufous colour of the 

 male and the much smaller size. 



It inhabits Oahu and is a very distinct form. It was, no doubt, more numerous in 

 former days. At present it must be decidedly rare, as only one male was obtained in the 

 course of many months. 



It was shot on April 20th in the mountains of the Wailua district, Oahu, by Palmer's 

 assistant, Wolstenholme. Mr. Perkins was present when he shot it, and neither he nor 

 anyone else has succeeded in observing another example. 



The specimens of Count Berlepsch and those belonging to the Liverpool Museum are 

 before me while I am writing this article, and Mr. Hartert has examined the Berlin 

 specimens with the type and Berlcpseh's for comparison. Needless to say, I have also, 

 together with Mr. Hartert, examined the three males in the British Museum. 



The Plate was lettered L. wohtenholmei before I discovered its identity with L. rufa, 

 It is delineated from the specimen obtained by Palmer.
