These specimens are specifically distinct from 

 those listed above as Holtbyrnia mazrops Maid ? 

 and may represent an undescribed species (R. J. 

 Lavenberg, personal communication). 



ARGENTINIDAE 



13. Nameniasp. 

 90.120, H6204, (1) 10.5 mm. 



This specimen was taken about 500 km., south- 

 east of Point Conception, Calif. There appear to 

 be two species of Namenia in the eastern North 

 Pacific — a more northern form described as N. 

 Candida by Cohen (1958: 53) and a more south- 

 ern form which is apparently undescribed. The 

 above specimen, because of its small size and the 

 intermediate location of its capture between the 

 known ranges of the two species, cannot now be 

 specifically identified (E. H. Ahlstrom, personal 

 communication). The familial classification of 

 this and the six following genera of argentinoid 

 fishes was proposed by D. M. Cohen (personal •com- 

 munication).

This specimen was taken about 275 km. (170
