674 CONSERVATIVE ORGANS. [LECT. Xf. 



wards. The trunk, also, if it may be so termed, 

 of this costa, which is close to the hinge of the 

 lid, supports a beautiful hook (2. a. p. 673), armed 

 with a cartilaginous, acute point ; and as this pro- 

 jects backwards, it may afford further support 

 to the full pitcher, by hooking it upon any firm 

 object in its immediate neighbourhood. The lid 

 (I. a.) exactly resembles a flat, orbicular, sessile 

 leaf; moveable at its insertion, being furnished 

 with an articulation, or hinge, immediately be- 

 hind which the hook is situated. But the most 

 curious part of the pitcher is the ring, which 

 distends its mouth. This is apparently a firm, 

 transversely ribbed, thick wire; but is really 

 formed of the lip of the pitcher, which is cartila- 

 ginous and transversely striated, rolled outwards 

 like a scroll. It terminates very abruptly at the 

 hinge of the lid, and is larger there than in the 

 fore part of the pitcher. 



The pitcher, in the early stage of its growth, 

 is of the same colour as the leaf; but, as it ad- 

 vances in age, it becomes beautifully coloured 

 with dark, purplish red streaks and blotches. 

 Its form in two of the species resembles that of the 

 finger of a glove; but in the third, the phyllam- 

 phora, it is contracted a little under the mouth 

 and again bulges out below, acquiring thus more 

 of the pitcher shape than the specimen before 

 us displays. It varies greatly in size, and some-
