\r not more than 1 3 arms 



c 1 all of the cirrus segments much broader than long, those in the distal 

 half of the cirri tvvice as broad as long; ossicles of the division series 

 and first four brachials with the dorsal surface raised into a broad blunt 

 keel, highest and most conspicuous on the first maned; brachials in 

 the proximal fourth or third of the arm with indications of a broacl low 

 median tubercle ; 10 arms 165 mm. long; cirri XX, 17 — 20, 20 mm. 



to 25 mm. long, very stout (Timor; 520 Metres) timorensis 



c 2 several, or most, of the cirrus segments as long as, or longer than, broad 

 d 1 cirri very stout, none of the segments longer than the distal diameter, 

 the outer broader than long, each with a prominent blunt carinate 

 process; ossicles of the IBr series with a plain and even surface, 

 or with a slight indication of a broad rounded median keel ; brachials 

 with an unmodified dorsal surface; 10 — ir stout arms about 180 mm. 

 long; IIBr 4 (3 + 4); cirri XXV, 18 — -22 (usually 20), 32 mm. long

d" cirri more slender, most, or all, of the segments slightly longer than 

 broad ; ossicles of the division series and first two brachials with the 

 median portion elevated into prominent broad keels or prominent, 

 more or less irregular, tubercles 



e 1 less than 20 (usually 15 — 18) cirrus segments; the median portion 

 of the ossicles of the IBr series and first two brachials is abruptly 

 raisecl into an irregular rounded tubercle; the remainder of the 

 dorsal surface of these ossicles is very uneven, and the proximal 

 and distal borders are more or less irregularly crenulate; 10 arms 

 115 mm. long; cirri XX, 15 — 20 (usually 15 — 18), 21 mm. long, 

 the outer cirrus segments bear small blunt terminal tubercles

ore than 20 (20 — 31) cirrus segments 



f 1 the dorsal surface of the ossicles of the division series and 

 first two brachials is rather sharply convex, rising into a broadly 

 rounded median ridge with a more or less distinct median 

 tubercle, so that the interradial angles appear sunken in a
