Figure 23. — Melita sulca (Stout), male, 12.0 mm., La Jolla, California, coll. Dr. T. E. 

 Bowman: a,b, gnathopod 1, medial and lateral views; c,d,e, pereopods 2, 4, 5. 



minal males, palm lacking teeth; gnathopod 1 of male with aberrant 

 melita-form of articles 6 and 7, article 7 malformed; eyes present, 

 dark; article 2 of pereopod 5 not produced posterodistally. Color 

 gray to black. 



Relationship. — Differing from Melita palmata (Montagu) (see 

 Sars, 1895, pi. 179) only by the possession of 4 teeth in 2 pairs on 

 urosomal segment 2, not a single tooth on each side. From its faunistic 

 relative, M. desdichada J. L. Barnard (1962b), which it resembles 

 by its pleonal tooth formula, M. sulca differs by the aberrant male 

 gnathopod 1 and the "palmata" kind of gnathopod 2. 



Material. — Vicinity of Friday Harbor, Washington, numerous 

 specimens in collections made by Dr. Paul L. IUg and Dr. Erik Dahl, 

 1951 to 1964; carmel: Macrocystis holdfast, scarce, cayucos: buried 

 cobbles, rare; in algae collected by Dr. E. Yale Dawson, July 15, 1960.
