SETTLEMENTS ON THE DEMERARY, &C. 237 



the female is more yellowish. The back of the female is co- 

 vered with granules, which may be considered as so many 

 teats, to which the offspring attach themselves The spawn 

 is deposited in ditches ; and the progeny, after acquiring the 

 tadpole form, is assisted by the father to fasten on the mother's 

 back, where they nestle until the second transformation is 

 completed. 



On the coast and in the rivers, are a variety of fish, many 

 of which differ so little from those which are well known in 

 England, that I shall only select the most curious for de- 

 scription. 



The lowlow is a salt water fish ; it is about six feet in length 

 and three feet in circumference. Its colour is a light blue, 

 with a metallic splendour. It has six fins, one pair a little be- 

 low the head, another pair on the belly, a single fin on the 

 back, and another large one at the end of the tail. It has a 

 long boney head and a wide mouth. 



The barroketa is about three feet in length, and two feet 

 in circumference ; it is much like a salmon, excepting in its 

 scales, which are larger, and its body which is rounder. 

 The barroketa is found in plenty at the upper part of rivers : 

 the flesh is white, fat, and delicate. This is the largest fresh 

 water fish found in our streams.
