Depth 6% to subcaudal origin; head 3%, width behind lateral 

 expansions 2 in head length. Snout 1% in head, lateral expansion 

 shorter than its width; eye 6 in head, 7^/^ in interorbital ; dentary 

 width 2% in head, length 2 in its width, without labial folds; teeth 

 immature, very small; nostril eye diameter before eye, without any 

 groove along front edge of hammer, which with only very slight 

 concavity before nostril as seen in front profile when viewed above; 

 interorbital space equals head length to last gill opening. Gill 

 openings rather large, last 2 above pectoral base and last shortest. 



Scales quindentate, points subequal, each with keel so that keels 

 parallel. 



First dorsal begins before hind inner pectoral angle, front edge 

 1 in head, falcate lobe and hind lobe short triangular point; second 

 dorsal inserted slightly behind anal origin, front edge 3 in head, 

 ends behind in long slender pointed lobe; anal little larger than 

 second dorsal, front edge 2A/iq in head, ends in slender pointed lobe, 

 behind shorter than that of second dorsal; caudal 2 in rest of body, 

 subcaudal lobe 2% in caudal fin; pectoral 1% in head, width 1% 

 its length; ventral length 2i/2 in head, claspers broad, flattened, 

 pointed and shorter than hind ventral lobe. 



Brown above, whitish beneath. Fins all with more or less grayish. 



Society Islands, New South Wales. This species is very close to 

 Sphyma zygaena, from which it is distinguished chiefly by the very 

 shallow concavities in the front profile line as the fish is viewed 

 from above. Moreover there is no groove along the front edge of 

 the hammer from each nostril as in Sphyrna zygaena.
