List of Birds collected in the Straits of Magellan. 183 



loris obscurioribus ; nigredine capitis nulla ; remigibus pri- 

 mariis extus pallide fuscesceute cauo marginatis, limbo 

 apicali lato, conspicuo et abrupte albo ; nigredine apicali 

 caudse minus distincta ; subalaribus dilute et sordide isa- 

 bellinis. 

 Juv. Similis foeminse, at sordidius tiuctus ; remigibus subcon- 

 coloribus, absque margine albo. 



In the old male the black loral band widens considerably in 

 the region of the eye and ear, and unites on the nape. The 

 feathers of the bastard-wing are blackish ; the alar margin is 

 white. 



I never found an opportunity of observing this bird in the 

 wild state. It seems to be confined to a very narrow district, 

 and to belong exclusively to the low Abyssinian coast- region. 



XV. — List of Birds collected in the Straits of Magellan by Dr. 

 Cunningham, with remarks on the Patagonian Avifauna. 

 By P. L. ScLATER, M.A., Ph.D., F.R.S., and Osbert 

 Salvin, M.A., F.L.S., F.Z.S. 



As already mentioned in the last number of ' The Ibis ' [supra, 

 p. 129, note), the specimens of birds collected by Dr. Cun- 

 ningham during the surveying-operations carried on by H.M.S. 

 'Nassau' in the Straits of Magellan, in the (antarctic) summer 

 of 1866-67, have been placed in our hands for identification. 

 The collection embraces sixty-one specimens, referable to forty- 

 four species, of which a list is herewith given, together with 

 some remarks we have put together concerning some of the more 

 obscure and less known of them. There are, besides, two or 

 three other species, collected at Maldonado, and " at sea," which 

 we have thought it better not to insert in the catalogue, as they 

 belong to a very different avifauna. 



Passing over the few species discovered by Forster and the 

 older voyagers, our principal knowledge of the avifauna of Pa- 

 tagonia is due to the collections made by Capt. King, Com- 

 mander of the 'Adventure/ in the years 1826-30, during the 

 first surveying-expedition of the Straits of Magellan, and to 

 the collections made by Mr. Darwin, naturalist of tlie 'Beagle'
