Obs. — In the lobule of this species there is one of the most 

 remarkable contrivances for the entrapping of small insects it is 

 possible to imagine : on the inner, antical face of the utriculate 

 lobule is a deep longitudinal fold having at the base a slit with 

 two decurrent wings hanging free within, one slightly concave, 

 the other plane — the unwary insect crawling through this slit, 

 the lid opens with the slight pressure and closes after the 

 prisoner has been secured; it is no unfrequent thing to find 

 the chitinous remains of several of these insects within the lobule. 

 It has not yet been clearly shown whether the plant derives 

 nourishment by the assimilation of these animals, but we may 

 rest assured that some object is served by this apparatus, and the 

 plant may not inaptly be called an insectivorous hepatic. The 

 late Dr. Gottsche was, I believe, the first to publish any notes o^
