AMPITHOIDAE FROM SOUTHERN CALIFORNIA — BARNARD 



11 



Females: Article 5 of gnathopod 1 ranging from shorter to longer 

 than article 6 (the latter, see Nagata, 1960), the larger the female, 

 the longer is article 5. Hence, the gnathopods of young females may- 

 be confused with those of A. valida and indeed are like those figured

 figured by Holmes (1904), apparently is a female of this species.
