364 GENLISEA ORNATA. [Cuap. XVIII. 



which are much elongated downwards beneath their points 

 of attachment. These two-celled papillae apparently cor- 

 respond with the bifid process in the upper part of the blad- 

 ders of Utricularia. The narrow transverse orifice (o, Fig. 

 29) is situated between the bases of the two spiral arms. No 

 valve could be detected here, nor was any such structure seen 

 by Dr. Warming. The lips of the orifice 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 papillae, 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 papilla} 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 close 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 debris 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 

 nock, except a living creature. Within the necks, however, 

 of some specimens, a worm with retracted homy jaws, the 

 abdomen of some articulate animal, and specks of dirt, prob- 

 ably the remnants of other minute creatures, were found. 

 Many of the papillce within both the utricles and necks were 

 discoloured, as if they had absorbed matter. 



From this description it is sufficiently obvious how Gen- 

 lisea secures its prey. Small animals entering the narrow 

 orifice but what induces them to enter is not known any 

 more than in the case af Utricularia would find their ^ress
