on the Birds of Chill. 39 



33. Sylviorthorhynchus desmursi, Gay. 

 Sylviorthorhynchus desmursi, Sclater, B. M, C. xv. p. 31. 

 These peculiar birds^ as a rule, occur only in the forest 



districts of the south, but I was informed that they migrate 

 a short distance to the north in winter-time. 



They frequent the densest undergrowth, especially the 

 quila, and are rarely seen, as they are very retiring by 

 nature. They have a somewhat shrill piping note, heard 

 more ft-equently at sunset, and kept up continuously in the 

 same key. It was tiie only note I heard them utter. They 

 are termed " Colilargo " by the natives. 



I observed some young ones, having apparently only just 

 left the nest, about the middle of February near Rio Bueno. 

 There were at least four in company. 



[There is no specimen of this bird obtained by Mr. Lane 

 in the British Museum, but he can hardly have mistaken 

 the species. — P. L. S.] 



34. Leptasthendra jEgithaloides (Kittl.). 

 Leptasthenura cegithaloides, Sclater, B. M. C. xv. p. 35 ; id. 



P. Z. S. 1891, p. 135. 



(Sacaya and Hacienda Mansel.) 



This species was common in Tarapaca, about Sacaya, and 

 occurs generally in similar localities, where it is apparently a 

 resident. 



The specimens I got in the province of Arauco appeared 

 to be of the same size and were similar in their habits to 

 those obtained in Tarapaca. Both closely resembled the 

 European Tits in all their habits, and also in their note, 

 which was not varied, being usually merely a twit when 

 feeding in company, but occasionally one uttered a querulous 

 chattering, somewhat like that of the Great Tit, but shriller. 



They fed in a Tit-like fashion on the twigs and branches 

 of shrubs, and appeared to be strictly arboreal. I observed 

 those of Tarapaca up to 12,000 feet. 



35. Pygarrhicus albogularis (King). 

 Pygarrhicus albogularis, Sclater, B, M. C. xv. p. 12G. 

 (Maqucgua.) 



This species is very characteristic of the forests of Southern
