Zoologij.-] NATURAL HISTORY OF VICTORIA. IPohjzoa. 



The cliaractcristic features are the loop-shaped mark or groove 

 from the lower lip, the aviculariiim on the middle of the cell, and 

 the permanent slit on the ovicell. 



It is allied to the European R. cellulosa, which does not occur 

 in my collection. The specimens referred to that species by Busk, 

 Hincks, and others, probably belong to the present. I think also 

 that Smith's Floridan R. marsupiata is identical with the more 

 slender form of our species.
