180 ON THE MORPHOLOGY OF 
Specimen A (Plate 219, fig. 2).—In general form this closely 
iepinhios cot foliage- ‘ira presenting a somewhat ovate blade 
the middle line. In this specimen we have the pitcher 
matty foreshadowed by the spoon-like excavation, while the keel- 
like ridge has sents the middle dorsal wing, which is a very 
Secmntiienit eature in the ee pitcher. 
Specimen B ‘(Plate 219, fig. 8).—Here the excavation has 
advanced to the formation of a ee somewhat elongated funnel
