this reason I am also inclined to retain the generic name 
Reniera for this sponge. 
A small specimen of it was found on the North Spit 
at Puffin Island, at low water, in September, 1887. The 
base of the specimen is about 2°5 cm. in height and 1 cm. 
in thickness. There are five branches arising from the 
base, three of which are broken off close to their origin, 
the two others are about 8 mm. in length by 3 mm. in 
diameter. The spicules are oxea, and measure about 0°3 
mm. They are arranged in multispiculous triangular or 
quadrangular meshes.
