becoming gradually elongated and twice as long as broad distally ; PP ,, and 3 ex- 

 actly like P, ; P^ 10 mm. long with ten segments, resembling the preceding; P^ 

 7 mm. long, spine-like as the preceding but somewhat more slender, with eight 

 segments; following pinnules decreasing gradually in length, P, being 5 mm. 

 long with eight segments ; subsequent pinnules remaining of similar length but 

 decreasing in stiffness and increasing in the number of segments, V^^ being 5 

 mm. long with twelve segments, the third squarish, the distal twice as long as 

 broad, only stiffened proximally ; distal pinnules slender, 9 mm. long. 



The colour in spirits is light yellowish brown.

Locality.— 0^ Colombo Light House, Ceylon; 26 J fathoms.— A single 

 specimen with twenty-one arms 50 mm. long, agreeing well with Hartlaub 's origi- 

 nal description and with a specimen at hand from Singapore belonging to the 

 Copenhagen Museum. P, has twelve segments. 



Other Records —Singapore; Matupi , New Britain ; Philippine Islands.

Habitat. — Philippine Islands ; Ceylon; Singapore; ? Suez. 



Depth. — Littoral, and down to 18 (? 30) fathoms. 



Remarks. — P.^, though not especially enlarged and about the length of the 

 succeeding pinnules, is more of the character of P^ and is somewhat stouter than 

 those succeeding ; it is flagellate distally. P.^ is strongly recurved and not erect 

 as it is in S. monacantha.
