interorbital ; dentary width 2% to 2% in head, length 1% in its 

 width, with very short inconspicuous upper labial groove; teeth 

 in 35 rows above, 30 rows below, serrated; nostrils about last % in 

 preoral space; internarial 1% in dentary width, anterior valve obtuse, 

 short; interorbital width 1% to 2 in head, broadly convex. Gill 

 openings small, equidistant, last 2 above pectoral base, fifth smallest. 



Scales tridentate, median point longest and each with three parallel 

 keels. 



First dorsal origin opposite inner pectoral angle, front edge V/s 

 to 2 in head, hind lobe narrow triangular point ; second dorsal origin 

 opposite anal origin, equal or slightly smaller in size than anal, front 

 edge 3 to 3% in head, hind lobe narrow triangular point ; front anal 

 edge 3 to 3-% ; caudal 2% in rest of body, subcaudal lobe 2Vi to 2% 

 in caudal length; pectoral li4to IV3 in head, width 1% to 2 in its 

 length ; ventral length 2i/4 to 3 in head. 



Largely uniform grayish brown, to little paler below.

 390 mm. 



U.S.N.M. No. 39990. Port Jackson. Australian Museum. Head and body skinned 

 out 1,110 mm. long. This shows: Snout 2l^ in head; eye lli/^, 5 in snout,

EULAMIA AHENEA Stead 



Eulamia ahenea Stead, Australian Nat., vol. 10, pt. 2, p. 98, 1938 (type locality: 

 4 miles east of North Head ; off Sydney Heads ; in 23 fathoms off South 

 Head of Port Jackson). 



Body somewhat compressed. Head broader than high, somewhat 

 flattened anteriorly ; tapers from gills. Snout moderate, rather mod- 

 erately rounded, narrow, shovel-shaped, not acute, length % greater 

 than mouth depth. Eye small, diameter % mouth depth, front 

 orbital edge just behind front edge of mouth. Mouth large, crescen- 

 tic, labial fold at angle short. Teeth almost erect in lower jaw, 

 well inclined toward angle in upper jaw, 32 rows above, 32 rows 

 below; bases broad in both jaws; cusps very narrow in lower jaw; 

 much broader in upper jaw, but considerably narrower than in 

 Eulamia hrachyura; deeply notched on posterior edge; upper teeth 

 finely serrate on bases and on cusps ; median upper teeth fairly large ; 

 median lower teeth small. Nostrils smaller than eye, % distance 

 from snout end to orbit. Gill openings fairly large; last one slightly 

 posterior to position of base of pectoral fin. 



First dorsal origin above end of posterior pectoral margin. Second 

 dorsal small; basal length equal to 1^ distance to caudal pit. Anal
