Centro-dorsal low hemispherical, the pole bare, with 40-.^0 cirri, 

 the longest (about the margin) reaching 35 mm. in length, and con- 

 sisting of about 20 (usuallv rather lt\ss) elongated joints, all of which 

 are longer than wide, the basal half very nuich so; apical cirri nnich 

 shorter and more slender, but with the same number of joints. 



First radials concealed; second radials short and wide, more or less 

 incised by the axillaries; axillaries rhombic in form, wider than high, 

 with the sides slightly concave, and considerably wider than the sec- 

 ond radials; 10 arms 130 mm. in length; the first brachial irregu- 

 larl}" quadrate, with a long outer and short inner edge; second brach- 

 ial irregularly (piadrate, with a long outer and short inner edge; 

 third brachial squarish; following brachials to the tenth irregularly 

 oblong with the borders somewhat, often strongly, tubercular; suc- 

 ceeding brachials triangular, about as wide as high, becoming quadrate 

 distally; syz3'gies in the third, eighth, and twelfth brachials, and dis- 

 tally at intervals of 2, sometimes 3, joints. 



First pinnule 20 mm. long, w^ith 35 joints, the proximal 12 short 

 and wide, mostly wider than long, the distal 23 extremely long and 

 slender; second pinnule somewhat less, with 20 joints, the 2 basal 

 wider than long, the basal 10 carinate, the distal 10 much elongated 

 and slender, and a large genital gland occupying the tliird to eleventh; 

 following pinnules like the second; distal pinnules long and very 

 slender, w4th 30 joints, the first two short and wide, the others greatly
