The much smaller expansion of the outer lip, ete., at once distin- 
guishes this species from QO. steboldi, which it most resembles. The 
animal of this species proves it to be a true Oxynoe. It is of a pale 
sea-green color, spotted with round torquoise-blue spots. It is found 
on reefs in very shallow water. (Jev.).

The species are few, but widely dispersed, coinciding remarkably 
with Oxynoe, in distribution. Only JL. serradifalci has been satis- 
factorily investigated.
