bones flexible, humeral spine absent; mandibular teeth few in num- 

 ber, depressible, cardiform, rather small, mainly in two rows, the 

 inner being the larger; two rows of similar teeth, unequal in size, near 

 symphysis of upper jaw, a single series of eight nondepressible teeth 

 on sides of premaxUlary ; a single canine on each side of vomer and a 

 row of four or five similar teeth on palatines; sides of disk and body 

 with a few small delicate filaments. 



First and second dorsal spines close together, near tip of snout, 

 threadlike, their bases overhanging receding edge of lip, first 1.93, 

 second 2.70, the third entirely covered with a loose fold of skin which 

 connects it with the soft dorsal, its base being slightly less than eye 

 diameter from this fin; soft dorsal well developed, its origin much 

 nearer tip of snout than tip of caudal, base 1.74 in head, longest ray 

 2.70; caudal 1.54, not as broad as long; anal 3.86; pectoral 2.16. 



Color in alcohol : Ground color pate drab gray, ventral surface gray, 

 darkest between ventrals and vent ; median portion of soft dorsal rays, 

 anal, and ventral surface of pectorals slate-black; caudal slightly 

 dusky; tongue brownish; peritoneum jet black. 



Type.— Csit. No. 70263, U.S.N.M., 13.7 cm. in length, taken with a 

 beam trawl at station 5605 (lat. 0° 21' 33" N.; long. 121° 34' 10" E.), 

 in Gulf of Tomini, Celebes, at a depth of 647 fathoms. 



This species is distinguished from S. gardineri of Regan by the 

 shorter head, ventrals and pectorals; by the presence of only three 

 dorsal spines, the first and second close to tip of snout ; by having the 

 caudal longer than deep; and by the well-developed supraorbital 

 spines.

 three-fourths diameter of eye apart, the posterior branch on left side 

 bifid, curved inward and upward, that on the right side single, almost
