Inhab. Pacific Ocean. 
Varies very much in shape, and has a white, red, and purple throat. The young is often deformed, 
being found in the crevices of rock and holes in corals, which sometimes do not allow their increase beyond a 
certain size. I am aware that many persons with isolated specimens will not allow them all to be varieties 
of one species, but I think the series I have bears me out in uniting them together.
