The Hijlory «/ ANIMALS. 91 
We have it about the coafts of Suffex, Kent, and Effex: moil of the writers on 
thefe fubjeds have defcribed it. Columns calls it Pudendum regale; Barthohne, 
Vermis aureus; others ; Vermis aureus, and Eruca marina grifeo-fufca; fome Mus 
Marinus, or the Sea Moufe. 
Aphrodita fuhrotunda . 
The roundijh Aphrodita . 
This is a moderately large fpecies: the fliape is nearly round, the back very convex, 
and the belly flatted : the fubftance is tender and gelatinous : it is covered with a quan¬ 
tity offline Abort hairs, of a greyifti, or bluiih, colour, with an admixture of yellow. $ 
thefe are longeft at the Aides, and have there more beautiful colours, than in any other 
part: in the center of the animal on the back, there is a fmall aperture of an oval 
figure, out of which water is difcharged in a fmall quantity, on preffing the creature . 
It is found on the Kentifh coaft, but not frequently. I have hot met with it 
elfewhere 
The other fpecies are, i. The large brown Aphrodita. 2. The large, depirefled, 
greyiAh Aphrodita. 3. The oblong and fubcylindric Aphrodita* 4 s The fmallei, 
bluiih Aphrodita.

T H E body of the Amphitrite is of an oblong figure, and has a great number of 
deep Arise, giving the appearance of numbers of lamellae : it has but one tenta- 
culum, which is of a flender and oblong form, refembling a piece of thread. 
Amphitrite firiis numerojis corpora Ititiore.

This is a large fpecies ^ it grows to an inch and a half in length, ahd to three quarters 
of an inch in diameter in the largeft part: it’s fhape approaches to an obtufely conic one % 
it’s fubftance is tolerably firm ; it’s colour a Bright pale blue, and in the fun it is very 
bright and gloflfy : the whole furface is covered with a vaft number Of flight furrows % 
the ridges between, which form a kind of lamellae, like thofe under the head of a fmall 
mufhroom : the tentaculum is near half an inch long, when exerted to it’s full length* 
and is white and foft.
