12 " ENDEAVOUR " SCIENTIFIC RESULTS. 



Twenty and a half miles S., 19° E. of Cape Everard, Victoria, 

 90 fathoms. 



One good specimen from an unknown locality, but the 

 appearance leaves little room for doubt that it is from the 

 station south-east of Cape Everard, Victoria. 



Family C0MA8TERID.E. 

 Genus Comatula, Lamarck. 



COMATULA CRATERA,! SJ). nOV. 



(Plate II., fig. 1.) 



Disk of holotype, 13 mm. across ; arms 175 mm. or more in 

 length, 4 mm. in transverse diameter at base, 5 mm. at 20 

 mm. distance from base, and 3| mm. at 50 mm. from base. 

 Centrodorsal pentagonal, 4 mm. in diameter ; its sides are 

 straight or more or less concave ; it is flush with the radials, 

 all of which are fully exposed. Cirri none in the holotype and 

 eight other specimens ; in three specimens, a single small 

 cirrus is present in each ; one specimen has two and one has 

 three such cirri, each with 16-19 joints. The second radial is 

 more than twice as high as the first and half again as wide ; 

 the third (axillary) is triangular, nearly twice as wide as high. 

 Brachials (beyond the tenth) broadly triangular, the pinnule- 

 bearing end three times as wide as the other ; the distal 

 margin is slightly concave and projects as a faint articular 

 tubercle where the brachial is widest ; the lowest brachials are 

 nearly equally wide on the two sides and have the articular 

 tubercle more marked on their proximal margins, but these 

 tubercles are never conspicuous. Along the median line of 

 the arm is a shght keel ; it is better marked on some brachials 

 than on others and the degree of development difl^ers in differ- 

 ent specimens. Syzygies between br. 1 and 2, and 3 and 4 

 and then at intervals of 5-7 joints to about br. 30, after which 

 the usual interval is 5, though 4 or 6 occur frequently. Pin- 

 nules rather stout but becoming long and slender distally ; 

 Pi about 20-25 mm. long, with some 45 segments, of which not 

 more than 12-15 make up the small terminal comb ; suc- 

 ceeding pinnules successively shorter to Pg which is about 

 16 mm. long and has some 25 segments ; terminal combs 

 confined to first three pairs of pinnules ; basal segments on 



1. K/)aT6/jo'= strong, stout, in reference to the unusually thick arms.
