only in having the snout slightly upturned and thickened 

 at the extremity. In the former specimen, the mouth 

 is furnished with the hairy processes characteristic of 

 ChaetostomuSy and the species seems to be identical with 

 the Chaetostcmus leucosticlus, in which the opercular 

 spines are short and few in number. 



Another fine Siluroid caught at the camp was the 

 maripak (Perincimpus typus), a fish of fine steel-blue 

 colour above, passing to grey below, and remarkable 

 from the peculiarly large and broad barbels which had

 This fish presents a very good example of the soft and 

 scaleless skin destitute of the osseous scutes so character-

 on the greater number of trees on the banks close by 

 the " Timehri " inscriptions. The forest apparently 

 abounds in valuable products, and some few years ago, 

 the district above VVarraputa was the head-quarters of 

 the trade in gums, tonquin beans, etc., carried on by 

 American collectors. A few miles above Warraputa, at 

 Hiawah, gold is also being obtained in paying quantities ; 

 so that the vicinity is an interesting one from many

It was at Warraputa, that the even tenor of our pro- 

 ceedings was varied by a little degree of excitement, due 

 to the non-return at night of one of the Indian huntsmen 

 who was a stranger to the district. The captain's great 

 horn was long and lustily blown, the guns were frequently
