This species, the first discovered of the genus, is the handsomest 
of them all, but not the largest. It is a very striking object, with its 
short upturned nose, and brilliant coloring. It is near neighbor of its 
relative the next species, R. pieri, their habitats separated probably 
by the River Blue, but does not equal it in size. Nothing is known of 
the habits of this species. The type is so faded from exposure to light 
that a description of it would be of no value.
