Type, No. 50860, U. S. Nat. Mus., a female about 1.48 meters long, taken at French Frigate Shoals.

7. Squalus mitsukurii Jordan & Snyder. Honolulu; station 4085, off the north coast of Maui. 
Head, measured to last gill-opening, 0.263 of length (snout to caudal pit); measured to first gill- 
opening 0.22; width of head 0.5 its length to last gill-opening; snout 0.417 of head measured to 
first gill-opening; interorbital space 0.417; height of first dorsal fin 0.5; second dorsal 0.29. 
Teeth in both jaws similar, except that the lower ones are slightly larger than those above; 
placed in three closely apposed rows, pointing away from middle of jaw; outer edge with a deep 
notch, inner serving as cutting edge; distance between mouth and tip of snout 0.5 of length of head 
to first gill-opening; width of mouth 0.29; length of fold at corner of mouth equal to distance between 
nostrils; distance between nostril and tip of snout 0.26 of head; between nostril and middle of mouth 
equal to distance between nostril and tip of snout; distance between spiracles 0.44 of head; length of 
gill area 0.22; diameter of eye 0.21. 
Length of exposed portion of first dorsal spine equals the distance from tip of spine to tip of fin; 
height of spine equal to length of base of fin. Second spine 0.75 as high as fin; distance between 
dorsals 3.66 times length of snout; pectoral, when depressed, reaching to a vertical through posterior edge 
of base of dorsal, the tip bluntly pointed; edges of pectoral and first dorsal concave, that of second dorsal 
emarginate; edge of ventrals straight; distance from anterior edge of anal opening to tip of depressed 
ventral 0.417 of head; upper caudal lobe 0.27 of the length; a low lateral keel on caudal peduncle. 
Color, dark slaty blue above, lighter below. 
Some of the specimens examined have the heads slightly narrower than examples of the same 
species from Japan, while others are like them in every particular
