 invested with spouge, is characterized by a subpectinate

rude, somewhat irregularly laminated, very minutely \ 



crenulately scaled; dull-brown. 

 Hab. Swan river, Australia.

 pearance.

L.vMARCK, Anira. sans vert. vol. vii. p. 268. 



Hab. Suez. 



Although it is a generic character of the Fulsella to 



have the umboes diverge from each other with advancing 



growth, they appear to be more than usually divergent in 



this species.

qud, antice hiante, rude laminatd, radiatim cremdato-
