favourable conditions, the bladders of a few species 

 which had been dried and preserved in herbaria. In 

 one of these {Utricularia montand) he found thirty- 

 two bladders on one small branch and seventy-three 

 on another, about two inches in length. In some of 

 the bladders of this species he found animal remains. 

 " The first contained a hairy Acarus, so much de- 

 cayed that nothing was left except its transparent 

 coat ; also a yellow chitinous head of some animal 

 with an internal fork, to which the oesophagus was 

 suspended ; also the double hook of the tarsus of 

 some animal ; also an elongated, greatly decayed 

 animal ; and, lastly, a curious flask-shaped organism 

 having the walls formed of rounded cells " (perhaps 

 the shell of a Rhizopod). 1 



In the Brazilian species, above alluded to by 

 Gardner, he found within one bladder the remains of 

 the abdomen of some larva or crustacean of large 

 size. In a Malayan species, 3 in one bladder there was 

 a minute aquatic larva ; and, in another, the remains 

 of some articulate animal. In the bladders of an 

 Indian species 3 were the remnants of Entomostraca ; 

 and the bladders of another Indian species 4 contained 

 similar remains. In like manner, in other species 

 from different parts of the world, the bladders enclosed
