in which we had fixed our stations. The exploration of the 

 neighbouring lake, very long but not wide (as these lakes 

 generally are, on both sides of the main river), which lay in 

 the same direction as the Capim and was separated from it 

 only by an elevation of some 80 metres, formed an agreeable 

 task, to which we dedicated two days. 



Here we obtained a full-grown Tapir and specimens of 

 Cairina moschata, Monasa nigra, and Ara macao. Exceedingly 

 common hereabouts during the night was the Giant Goat- 

 sucker [Nyctibius jamaicensis). During the day Phlogopsis 

 nigromaculata, called ' ' mae da taoca," was often heard around 

 our encampment in the forest. A brown-black middle-sized 

 Thamnophilus was always crying " br-br-br " in the lower 

 vegetation. On the declivity of a soft earth-wall on the side 

 of a sort of artificial defile, where evidently in former times 

 a way had been cut from the river to the lake, I discovered 

 the entrance-hole of the subterranean breeding-quarters of 

 the " Tanguru-para" {Monasa nigra). Unfortunately I had 

 no implements with me with which to dig out the gallery 

 and nest, as I washed to do, in order to get an exact idea 

 of their architectural structure. 



On the 1 2th of July, at 5 o'clock p.m., we left "Tracua-teua," 

 rowing downwards the whole night and all the next day. 

 We saw and heard Columba plumbea, Ar amides chiricote, 

 Ibycter americanus, Falco rufigularis, Ardea virescens, Monasa 

 nigra (frequently), Rhamphastus ariel and R. erythro- 

 rhynchus, Chrysotis amazonica, Pionias violaceus, Momotus 

 brasiliensis, and Phlogopsis nigromaculata. But the most 

 interesting occurrence was a small flock of three individuals 

 of Hoplopterus spinosus at Praia Granda on a sand-bank. I 

 shot two of them, the third escaped. 



Not far from the mouth of the affluent " Caudiru-aju/' we 

 noted Ara macao, Parra jacana, Cathartes urubitinga, Ardea 

 leuce, and Ceryle of several species. On the whole I was 

 surprised to see so few Herons along the Capim. 



We reached Sao Luiz at 4.45 p.m. on the 13th of July, 

 and remained there the next day. We had a bad night, 

 with incessant rain, followed by an exceedingly hot day;
