deeper colour on the back and Tides, and pale on the belly; the head is comprelfed; 
the body is fomewhat compreffed alfo, but it is To little, that it has a rounded look: 
the eyes are large, and their iris is yellow j the beards are Ihort, white, and flelhy - 3 
the back fin has eight rays ; the pedtoral fins have each of them twelve 5 the belly fins 
have Teven rays each, and the pinna ani has fix. 
We have this fpecies in Tome of our thallow brooks; all the writers on fifhes have 
defcribed it. Rondelet and Gefner call it Cobitis barbatula j Ray and Willughby, 
Cobitis fiuviatilis barbatula 5 and fome authors, Fundulus and Grundulus. It always 
keeps at the bottom, among the loofe pebbles, and often gets under large Rones,

This is about three inches and a quarter in length, and about half an inch, or 
fomewhat lefs than that, in diameter, in the largeft part: the head is of a deprefled 
figure and oblong, and the roftrum is bent fomewhat downwards; the body is alfo of 
a deprelfed form and thin, and is fomewhat broader toward the head than elfewhere^ 
but it is nearly equal in breadth all the way : the upper jaw is longer than the under^ 
and clofes over it, receiving it in the manner that the lid of a box does the body : the 
opening of the mouth is very narrow; there are fix cirri or beards about it; two of 
them are placed on the upper part of the mouth, two on the lower, and two on the 
fides; they are all ilender, oblong, and white ; the noftrils are in the middle, between 
the eyes and the mouth: the eyes are fmall, and are fituated on the fides of the upper 
part of the head; their iris is white in the lower part, and of a dulky colour above : 
on each fide of the head near the noftrils, and below the anterior part of the eye, 
there ftands a little bone of a whitilh colour, bifid at the top, and prickly j the exte¬ 
rior point is Ihorter than the interior: the branchiae are four on each fide: their co¬ 
verings are oblong, and are open fideways only near the pedtoral fins, not on the 
lower part: there are no perceptible teeth in the mouth, nor is there any diftin&ly vi- 
fible linea lateralis: the fcales are roundilh and very fmall; they are fo thin, and laid 
fo clofe on one another, that they are not vifible in the recent filh, but in the dried 
fpecimens of it they are diftind enough : the back is of a dulky colour j the fides are 
variegated with many whitilh lines, and a number of very minute, black dots 5 the 
belly is white. 
The pedoral fins are Ihort, and have each eight rays; the firft of thefe is undi¬ 
vided j the fecond, which is the largeft of all, is bifid or ramofe at the top, as are 
alfo all the others: the colour of the fin is white; there is one fin on the back, which 
is variegated with dulky fpots j this has nine rays in it 5 the firft is the largeft and un¬ 
divided, the reft are bifid or ramofe at their top; the belly fins are white, and have 
feven bones or rays each : the pinna ani ftands a little behind that aperture; it has 
eight rays, the two laft very fmall and indiftind : the tail is Ihort, rounded at the ex¬ 
tremity, and fpotted with black ; it has eighteen bones or rays: there is a little pro¬ 
minence in this fpecies between the anus and the origin of the pinna ani. 
The heart is fmall, not exceeding a grain of hempfeed in fize : the liv^r is long and 
red ; it lies upon that part of the inteftine, which performs the office of a ftomach, 
and is joined to it by a membrane. 
This lies in flow rivers, and fometimes in lakes and ponds. Rondelet, Aldrovand, 
and others call it Cobitis aculeata 5 Willughby and Ray, Cobitis barbatula aculeata 5 
Schonveldt, Tania cornuta.

This is a fpecies very lingular in it’s manner of living, as well as in it’s figure : it is 
live inches long, and fomewhat more than half an inch in diameter: the head is Ihort, 
broad, and obtufe ; the belly is fmooth, and of a bluilh colour, with ten black longi¬ 
tudinal lines running down it, five on each fide of the back : about the mouth there 
are placed a number of cirri or beards; they are not fewer than ten, and are whitilh
