This species bore the same specific name as one previously defined 
by Gould, and apparently belongs to the same genus. 
N. CIRRHIFER Quoy & Gaimard. PI. 17, fig. 11. 
Quite a large species (length 3 inches), with elevated back and 
long neck, having the lips extended, buccal appendages broad, and 
tentacles very long. The contracted foot is rounded in front, pro- 
longed to a point behind. Entire body and tentacles covered with 
slender ramifying processes. The integument is somewhat diaphan- 
ous, of a grayish tint, with plaques of light brown in the center of 
which are emerald dots, but some are circles of reddish. The pro- 
cesses are generally parchment-white to yellowish. The gill may 
project to the exterior and form a semicircle on the right side. It 
is composed of a dozen main branches, of a greenish color striated 
with brown. The penis is large, very long, marked with white dots 
at the base. (Q. & G.). 
Length 10, breadth 3, alt. 3 em. Gray-green with brown punct- 
ulation; the back, sides and head with light blue dots, each sur- 
rounded by a yellow ring ; many of these peacock-eye spots are en- 
circled by brown lines. The entire integument is beset with conic 
papilla; the larger papille of the back bear smaller papille. 
Tentacles with long papille. Sole narrow. Gill gray-green with. 
brown strie. (Mobius).
