 that may approach, but leave it undisturbed to 

 their hungry neighbours. 



The long arms seem to grow out singly, as one 

 may always be distinguished as the thickest and 

 longest. In some very large individuals of the 

 Physalia glauca we observed, indeed, two remark-

 the other. They are all provided at the root with 

 the above-mentioned muscular feeler. The tu- 

 bercles described by authors on the proboscis of 

 the bladder of the Physalia glauca^ which is found 

 in abundance near the Cape of Good Ho})e, are 

 nothing more than little stomachs, that have not 

 attained their complete growth. I have convinced 

 myself by the examination of some full-grown spe- 

 cimens. In one of them, which must have made 

 a good booty just before, not only all the stomachs

 also the above-mentioned tubercles on the pro- 

 boscis were filled with a reddish grainy mass ; be-
