MALACOSTRACAN FAUNA OF THE MEDITERRANEAN. 303 
about half the length of the posterior margin with which it forms 
an angle of about 45 degrees. 
Perxopods: the first three pairs have the 1st joint very long 
and narrow ; in the last two pairs it is about half as long again 
as wide; dactyli strong, about half as long as the preceding 
joint. 
Uropods: the shorter ramus of the second pair reaches the 
distal end of the peduncle of the 3rd pair, which project a little 
beyond the first pair. 
Telson of the usual form, reaching nearly to the end of the 
3rd uropod. 
This little species differs from all others known to me in 
the projecting anterior angle of the propodos, its short and 
well-defined palm, and short, wide dactylus, from which it takes 
its specific name.
