38 DARWINISM STATED BY DARWIN HIMSELF. 



in the upper part of the neck, but differing slightly from 

 them, according to Warming, in their footstalks being 

 formed by prolongations of large epidermic cells ; where- 

 as the papilla3 within the neck rest on small cells sunk 

 amid the larger ones. These spiral arms form a conspic- 

 uous difference between the present genus and Utricu- 

 laria. 



Lastly, there is a bundle of spiral vessels which, run- 

 ning 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 recognized. 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, probably the remnants of other minute 

 creatures, were found. Many of the papillae within both 

 the utricles and necks were discolored, as if they had ab- 

 sorbed matter. 



From this description it is 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,
