specimens made, especially after the accident at Seba, 

 was very scanty. Two of the rather uncommon brown 

 two-toed sloth (Choloepus dida6lylus) , mother and 

 young, had been shot just within the opening of the 

 Manabadin creek ; three specimens of the red-throated 

 chatterer (Pyroderus scutatusj, had been procured 

 along the path at Mallali ; three good specimens of night- 

 jars or goatsuckers, of an uncommon species, had been 

 obtained one evening at Mule-pen, opposite Derrire 

 Hill ; while several of the beautiful red-backed hangnests 

 (Cassicus affinis) had been taken at various points along 

 the river, where they frequented the large trees in the 

 clearings with dozens of their long nests hanging 

 from the ends of the branches. Besides these, a few 

 of the large and handsome king-fishers (Ceryle tor- 

 quata and C. amazcnica) , and the large yellow-tailed 

 black bunyas (Ostinops decumanus) , and other birds 

 which frequent the water-side, had been added to the 

 colledlion. The so-called bush carrion crows or bultata 

 (Ibydler americanus) , which were constantly, to be 

 heard hoarsely and discordantly cawing in the high 

 tree-tops, and of which I particularly desired to 

 obtain specimens, never gave a good chance of a shot, 

 though they were frequently seen. 



A very interesting form of the lizards, the Chalcis 

 (Cflavescens) , had been obtained at Cumparu, together 

 with a coecilian ; but, with the exception of these, scarcely 

 a reptile had been seen. The chalcis lizard is very 

 peculiar in appearance, being small and snake-like, 

 possessing two pairs of extremely minute limbs, in 

 which three digits are but barely represented by 

 minute divisions. The elongated tail is very easily
