was any such structure seen by Dr. Warming. The lips of 
the oritice are armed with many short, thick, sharply pointed, 
somewhat incurved hairs or teeth. 
The two projecting edges of the spirally wound lamina, 
forming the arms, are provided with short incurved hairs or 
teeth, exactly like those on the lips. These project inwards 
at right angles to the spiral line of junction between the 
two edges. The inner surface of the lamina supports two- 
celled, elongated papille, resembling those in the upper 
part of the neck, but differing slightly from them, according 
to Warming, in their footstalks being formed by prolonga- 
tions of large epidermic cells; whereas the papille within 
the neck rest on small cells sunk amidst the larger ones. 
These spiral arms form a conspicuous difference between the 
present genus and Utricularia. 
Lastly, there is a bundle of spiral vessels which, running 
up the lower part of the linear leaf, divides cluse beneath 
the utricle. One branch extends up the dorsal and the 
other up the ventral side of both the utricle and neck. Of 
these two branches, one enters one spiral arm, and the other 
branch the other arm. 
The utricles contained much débris or dirty matter, which 
seemed organic, though no distinct organisms could be 
recognised. It is, indeed, scarcely possible that any object 
could enter the small orifice and pass down the long narrow 
neck, except a living creature. Within the necks, however, 
of some specimens, a worm with retracted horny jaws, the 
abdomen of some articulate animal, and specks of dirt, pro- 
bably the remnants of other minute creatures, were found. 
Many of the papille within both the utricles and necks 
were discoloured, as if they had absorbed matter. 
From this description itis sufficiently obvious how Genlisea 
secures its prey. Small animals entering the narrow orifice 
—but what induces them to enter is not known any more 
than in the case of Utricularia—would find their egress 
rendered difficult by the sharp incurved hairs: on the lips, 
and as soon as they passed some way down the neck, it 
would be scarcely possible for them to return, owing to the 
many transverse rows of long, straight, downward pointing 
hairs, together with the ridges from which these project. 
Such creatures would, therefore, perish either within the 
neck or utricle; and the quadrifid and bifid papilla would 
absorb matter from their decayed remains. ‘The transverse
