spinelike and are enlarged in proportion to their length. The color is dull whitish 

 with narrow bands of yellow brown on the arms and cirri. 



The description given for the species is based upon the type specimen from 

 Albatross station 5147. The type specimen of Stephanometra coronata from "India" 

 may be described as follows: The cirri are XXII-XXIII, 25-30, 22 mm. long, and 

 resemble those of S. tenuipinna; the longest segments are about one third again 

 as long as broad; the ninth, tenth, or eleventh is a well-marked transition segment. 

 The radials project slightly beyond the edge of the centrodorsal. The IB^ are 

 oblong, short, about three and one-half or four times as broad as long, with a rounded 

 ventrolateral process in the proximal half, and are not in lateral apposition. The 

 IBr 2 (axillaries) are broadly pentagonal, twice as broad as long, with the lateral edges 

 about half as long as those of the IBr! and produced into prominent rounded ventro- 

 lateral processes. The IIBr series, IIlBr series, and JVBr series, when present, are 2, 

 resembling the IBr series. All the ossicles of the division series and the first brachials 

 have prominent ventrolateral processes; the synarthrial tubercles are rather prom- 

 inent. The 33-34 arms are 120 mm. long, in general resembling those of S. tenuipinna. 

 PI is long, stout, stiff, and spinelike, composed of 14 segments, of which the first two 

 are somewhat broader than long, the third-fifth are about as long as broad, and the 

 remainder become gradually elongated and twice as long as broad distally. P 2 and 

 P 3 are exactly like PI. P 4 is 10 mm. long, with 10 segments, resembling the pinnules 

 preceding. P 5 is 7 mm. long, spinelike as are the preceding but somewhat slenderer, 

 with 8 segments. The following pinnules decrease gradually in length, P 8 being 5 

 mm. long, with 8 segments. The succeeding pinnules remain of similar length but 

 decrease in stiffness and increase in the number of segments, P n being 5 mm. long, 

 with 12 segments, which become as long as broad on the third and twice as long as 

 broad distally and only stiffened proximally. The distal pinnules are slender, 9 mm. 

 long. 



Remarks. It is possible that this form will eventually prove to be simply full 

 sized S. tenuipinna, but until definite evidence of their identity is available it seems 

 best to keep them separate.
