This species was listed as a subspecies of Stomias 

 boa (Risso) by Ege (1934:23) but is now gen- 

 erally regarded as a distinct species. In a few of 

 the 78 specimens collected during the survey, the 

 barbel was broken off, but the normal three equal- 

 sized filaments at the end of the barbel were pres- 

 ent in the others, except one. On the exceptional 

 specimen, one of the three filaments was branched 

 to near its base, giving the superficial appearance 

 of four filaments at the end of the barbel.

 110.35, H6204, (1) 189 mm. 



This specimen, occurring within the range of S. 

 atriventer, represents either a morphological var- 

 iant or an undescribed species. It differs in a 

 number of characters from S. atriventer and from 

 all known species of Stomias in having six equal- 

 sized filaments, each with a separate base, at the 

 end of the barbel. 



MELANOSTOMIATIDAE 



48. Leptostomias sp. 

 90.200.C6208, (1) 186 mm. 



This specimen was taken about 1,000 km. (620 

 miles) WSW. of Point Conception, Calif. The 

 number and taxonomic limits of the species of this 

 genus are uncertain, and this specimen is not spe- 

 cifically identified, pending needed study of the 

 genus. 



49. Oposfomias mMsuii Imai. 



60.80, C6208, (1) 164 mm.; 83.77, C6303, (1) 77 mm. 



These specimens, taken about 185 km. (115 

 miles) west of San Francisco and about 195 km. 

 ( 120 miles) SE. of Point Conception, Calif., are 

 the first of this species to be reported from waters 

 off California. The three known species of this 

 genus, including 0. micripmts (Giinther) and O. 

 gibsonpaoei Barnard, appear to be valid, but 

 further comparison is necessary (R. IT. Gibbs, 

 personal communication) .

80.80, H6204, ( 1 i 13-1 mm.; 87.80, C6303. I 1 > 186 mm. 



These specimens, taken about 200 and 240 km. 



( 125 and L50 miles) off Point Concept ion. Calif., 



differ only slightly from the detailed description 

 of F. boureei from the western Atlantic by Beebe 

 and Crane (1939 : 179-185). Comparison of other 

 Atlantic and Pacific specimens indicates that they 

 are the same species (R. H. Gibbs, personal 

 communication). 



51. M elanostomim valdiviae Brauer. 



86.92, C6303, (2) 163-175 mm. 



These two specimens taken about 305 km. (190 

 miles) SSW. of Point Conception, and one speci- 

 men in the collections of Scripps Institution of 

 Oceanography collected off San Juan Seamount, 

 constitute the first records of this species in this 

 area.

These specimens appear to be this species, re- 

 described from material from the North Atlantic 

 by Beebe and Crane (1939: 175-179). The above 

 listed specimens vary considerably in several 

 characters, especially barbel structure (at least 

 some of this variation is ontogenetic). Although 

 more than one species may be represented, the 

 variation in barbel structure is thought to be 

 intraspecific.
