tinguifhable from the other two divifions,hy its thinnefs, 
its apparent laxnefs, and by the reticulated ikin of a 
more grey and light colour, with which it is covered. 
When the animal fwims gently in pretty deep water, the 
rhomboidal reticulations of the Ikin of this carina are 
very difcernible ; but when the water is fhallow, or the 
depth of the carina is contracted, thefe reticulations ap- 
pear like many irregular longitudinal plica. The carina 
begins about lix or feven inches below the bafe of the 
head, and gradually widening or deepening as it goes 
along, reaches down to the tail, where it is thinneft. It 
feems to be of a flrong mufcular nature. Where it firft 
takes its rife from the body of the fifh, it feems to be 
about one inch or one inch and an half thick, and is 
gradually fharpened to a thin edge, where the fourth 
and laft part is fituated; videlicet a long, deep, foft, wavy 
fin, which takes its rife about three or four inches atmofi: 
below the head, and runs down along the fliarp edge of 
the carina to the extremity of the tail. Where it firft 
rifes it is not deep, but gradually deepens or widens as it 
approaches to the tail. It is of a very pliable foft con- 
fiftence, and feems rather longer than the body. The 
fituation of the anus in this fifh is very fingular, being 
placed underneath, and being about an inch more for- 
ward than the peCtoral fins, and confequently confidera- 
bly nearer the rojirum. It is a pretty long rima in ap- 
pearance ; but the aperture muft be very fmall, as the 
formed excrements are only about the fize of a quill of 
a common dunghill fowl. There are two peCtoral (if I
