In this series the horns vary in the male from the same length as the carapace to § 

 of the carapace ; and in the female from % to f- of the length of the carapace. In the very 

 young, the postocular lobe appears like a bifid spine, being much more slender in top view 

 and not so flattened on the side. 



Many of the specimens are disguised by a growth of sponges, tunicates, hydroids or 

 alcyonarians.
