MALACOSTRACAN FAUNA OF THE MEDITERRANEAN. 305 
Mara sctsstmana (Costa). 
Gammarus scissimanus, Costa. Mera truncatipes, Della Valle. 
St. 2H. Two males, one female. Length 5 mm. 
The characteristic notch in the palm of the 2nd gnathopods is 
wanting in a young male. This may be the form described by 
Heller as MW. integrimana, which appears to be the opinion of 
Della Valle, as he treats the two species as synonymous. A 
female taken with the males has the lower antenne shorter and 
the limbs stouter.
