the tube into the neck, and so into the utricle. If the 
creature perished within the spiral arms, its decaying 
remains would be absorbed and utilised by the bifid 
papilla. We thus see that animals are captured by 
Cenlisea, not by means of an elastic valve, as with 
the foregoing species, but by a contrivance resembling 
an eel-trap, though more complex. 
Genlisea africana (South Africa).—Fragments of the 
utriculiferous leaves of this species exhibited the 
same structure as those of Genlisea ornata. A nearly 
perfect Acarus was found within the utricle or neck 
of one leaf, but in which of the two was not recorded. 
Genlisea aurea (Brazil)—A fragment of the neck 
of a utricle was lined with transverse rows of hairs, 
and was furnished with elongated papille, exactly 
like those within the neck of Genlisea ornata. It is 
probable, therefore, that the whole utricle is similarly 
constructed. 
Genlisea filiformis (Bahia, Brazil)—Many leaves 
were examined and none were found provided with 
utricles, whereas such leaves were found without diffi- 
culty in the three previous species. On the other 
hand, the rhizomes bear bladders resembling in essen- 
tial character those on the rhizomes of Utricularia. 
These bladders are transparent, and very small, viz. 
only ;4, of an inch (‘254 mm.) in length. The 
antenne are not united at their bases, and apparently 
bear some long hairs. On the outside of the bladders 
there are only a few papilla, and internally very few. 
quadrifid processes. These latter, however, are of un- 
usually large size, relatively to the bladder, with the 
four divergent arms of equal length. No prey could 
be seen within these minute bladders. As the rhizomes 
of this species were furnished with bladders, those of 
Genlisea africana, ornata, and aurea were carefully
