the tube into tlie 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 

 papillae. We thus see that animals are captured by 

 Genlisea, not by means of an elastic valve, as with 

 the foregoing species, but by a contrivance resembling 

 an eel-trap, though more complex. 



Genlisea afrieana (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 papillce, exactly 

 like those within the neck of Genlisea ornata. It is 

 probable, therefore, that the whole utricle is similarly 

 constructed. 



Genlisea filiforniis (Bahia, Brazil). — Many leaves 

 were examined and none were found jDrovided 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 -j-^ of an inch ('254: mm.) in length. The 

 antennae are not united at their bases, and apparently 

 bear some long hairs. On the outside of the bladders 

 there are only a few papillae, 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 afrieana, ornata, and aurea were carefully
