In consequence of the priority of Donovan’s specific name, denti- 
cornis, I have considered it necessary to give this another denomina¬ 
tion, and which has reference to the uniformity of its colour, by 
which it is distinguished from the preceding species. 
The curious leafless plant represented in the plate, is the Indian 
Utricularia reticulata. 
Want of space, in a preceding page, prevented me from giving 
the following summary of Dr. Burmeister**s views of the relations of 
the Paussidfe with the other carnivorous families, which I now add; 
there will be occasion to refer to it in my observations on the genus 
Paussus in a future number.
