668 Mr. M. J. Nicoll on the Birds collected and 



On December 10th we anchored at Bahia, where we were 



delayed until December 30th. During our stay we made 

 several excursions to the Island of Itaparica, about five miles 

 from Bahia, and on two occasions camped for two nights 

 there. I collected examples of seventy species of birds on 

 this island, as well as mammals. The following notes refer 

 to some of them : — 



Emberizoides macrurus. — Only found on one small marsh, 

 where several individuals were seen feeding on grass- 

 seeds, and three adults were obtained, besides an 

 immature bird. 



Furnarius figulus and Arundinicola leucocephala were met 

 with only after rain ; only one example of the latter 

 species was seen. 



Myiarchus pelzelni Berl. — This rare and little-known species 

 was found singly or in pairs among the clumps of mango- 

 trees which grow in abundance in the open glades of 

 the forest. At a distance it is easily mistaken for 

 M. ferox ; in fact, when working out the collection 

 1 obtained on Itaparica in 1902, I referred an example 

 of M. pelzelni to M. ferox. Herr C. E. Hellmayr 

 having kindly pointed out to me the difference between 

 the two forms, 1 kept a special look out for them during 

 this voyage and obtained four examples of M. pelzelni. 

 This species is generally much paler than M. ferox, 

 especially as regards the crown and mantle. The throat 

 and chin are of a more pure bluish grey colour and \\w. 

 abdomen slightly yellowish. The bill of M. pelzelni is 

 also pale brown, not dark brownish black as in M. ferox, 

 while the tarsus is usually shorter and slighter. 



Elainea albivertex. — Only one example of this species was 



met with on Itaparica. 

 Chceturo. fumosa. — A number of these little Swifts usually 

 appeared during the afternoon on a small lake near our 

 camp, and after a few minutes disappeared and were 

 seldom seen again until the following afternoon.
