142 Descriptions of New Spiecies of Achatinella: 



with, the attachment of the one on the opposite side of the 

 stalk. 



1; The flower resembles somewhat in form the Roman helmet 

 inverted, and is attached, as it were, by the point of the crest to 

 the stalk. It is a fleshy mass, and the cavity of the calyx 

 extends in a tortuous manner downwards, towards the attach- 

 ment of the flower to the stalk. , 



" The color of the flower is a deep crimson, and the stalk has 

 the same, excepting that it is of a much darker shade. So 

 much for the description of the plant and flower. 



"With regard to the bird again, I may add, that I have 



secured two specimens of it, which were the only ones I ever 



saw feeding, and in both instances they were feeding from the 



flower I have just described.
