Bonnierella linearis californica, new subspecies 



(Fig. 11) 

 Bonnierella linearis J. L. Barnard 1964a: 42-43, fig. 33. 



Diagnosis: Male gnathopod 1 conspicuously smaller than gnathopod 

 2, palm smooth ; gnathopod 2 with posterior margin of article 6 shorter 

 than palm, palm with 3 sharp or prominent cusps, that nearest dactylar 

 hinge slightly bifid ; apex of telson more rounded than in typical sub- 

 species; article 2 of gnathopod 2 not produced distolaterally ; apex of 

 outer ramus on uropod 3 with very short knobs in contrast to 

 elongated projections of typical subspecies; lateral cephalic lobe typi- 

 cally very sharp. 



Holotype: AHF No. 608, male, 3 mm. 



Type locality: Station 6348, Tanner Basin, 32°-37'-30"N, 119°- 

 27'-50"W, 1292 m, August 16, 1959. 



Basin material: The holotype and a female, 2.75 mm, from station 

 6339. 



Relationship: This material bears closer relationship to B. linearis 

 J. L. Barnard (1964a), described from Peru, than to other species in 

 the genus and although several good differences are present I have de- 

 cided to recognize them only at the infra-specific level. The female 

 gnathopod of the new subspecies is more strongly ornamented on the 

 palm than in B. linearis linearis but this may be a matter of age dif- 

 ference. 



These specimens have very distinct epistomal processes, similar to 

 the process of B. lapisi (J. L. Barnard 1962d) and probably indicate
