female has no fuch bag. Since therefore the bag of 
oar Polypus is found in the fame fituation as that of 
the Calamary, (which is alfo a kind of Polypus) we 
mayfuppofe it to be the milt bag, and that our Po- 
lypus is a male, taken at a time when the milt was 
ready for ejection. In the dried fpecimen at the 
Britifh Mufeum, and alfo in the other fpecimens, 
there is the fame opening, with the pipe that rifes 
above it towards the arms, but not the lead appear-^ 
ance of the bag in queftion : they are therefore pro- 
bably females, or if males, were caught before fuch 
bag was formed. 
Fig. 3. prefents another view of this Polypus, its 
arms extended circularly with their under- fides next 
the eye, and the body fo difpofed as to fhew the 
tranfverfe opening a> the oval bag iffuing therefrom b>. 
and the pipe riling upwards towards the arms c . 
Fig. 4. (hews the Polypus with its tranfverfe open- 
ing and the pipe rifmg therefrom, but without the oval, 
bag; it is figured thus by Rondeletius and Gefner, 
and the fpecimen at the Britifh Mufeum has alfo this 
appearance. It is here fhewn with the arms exten- 
ded forwards. K is a magnified figure of one of the 
acetabula , or fuckers > of v/hich there are two rows 
on each arm of this Polypus, as before deferibed. 
Mr. Needham, in his defeription of the fuckers of 
the Calamary, (which, he had many opportunities of 
examining whilft alive, and whofe mechanifm is pro- 
bably the fame as in thofe of our Polypus) informs- 
us, “ that the adtion of the fuckers depends partly 
‘ k on their fhape, which, when, they are extended; 
“ refembies nearly that of an acorn-cup, and partly 
“ upon a deep circular cartilaginous ring, armed with 
“ fmall hooks, which is fecured in a thin membrane
