STOMIATIDAE 313 



terminal filaments arranged as shown in the accompanying figure ; long filament with a 

 luminous sweUing at the tip. Dorsal 22 (?). Anal 38. Pectoral 3. Pelvic 7. Photo- 

 phores — in ventral series I-P 7; P-V 26; V-A 12; A-C 19: in lateral series 0-V 26; 

 V-A 12. 



Described from a single specimen, 58 mm. in length; holotype of the species. 



Hob. Atlantic. 



Apparently related to E. enbarbatus, Welsh, differing chiefly in the form of the barbel. 

 Named for Dr C. Tate Regan, F.R.S., in recognition of his work on the 'Dana' 

 Stomiatoids.

 156 mm. 



Hah. Atlantic. 



According to the label the basal half of the proximal swelling of the barbel was 

 coloured pink in life, the apical half and the distal swelling being cream coloured. 



Eustomias (Nominostomias) trewavasae, n.sp. 



St. 79. 13. vi. 26. 34° 48' 00" S, 16° 36' 00" VV. 4I m. net, horizontal, 1000 (-0) m. : i specimen, 

 60 mm. 



Depth of body 12 in the length, length of head (with snout produced) about 8. 

 Diameter of eye about 5 in length of head. Barbel more than \ length of fish; 3 bulbs, 

 the middle one close to and somewhat larger than the distal one, which bears a knob- 

 like process at its extremity but no filaments ; a small luminous swelling on the stem at 

 some distance from the proximal bulb ; a bunch of about 6 filaments, deeply pigmented 

 at the base comes off from the stem just distal to the first bulb. Dorsal 23 (?). Anal 

 35 (?). Pectoral 3. Pelvic 7. Photophores — in ventral series I-P 7; P-V 32; V-A 16; 

 A-C 15: in lateral series 0-V 32; V-A 16. 



Described from a single specimen, 60 mm. in length; holotype of the species. 



Hab. South Atlantic. 



This species appears to be rather close to E. variabilis, Regan and Trewavas, and E. 

 trituberatus, Regan and Trewavas, differing from both chiefly in the form of the barbel. 

 Named for Miss Ethelwynn Trewavas, in recognition of her work on the 'Dana' 

 Stomiatoids.
