Florometra spinulifera JOHN, Rep. B.A.N.Z. Antarctic Res. Exped. 1929-31, ser. B, vol. 4, pt. 6, 1939, 

 p. 191 (listed), pp. 199-201 (locality; description; comparison with F. mawsoni); fig. 2, p. 200. 



Diagnostic features. The cirri have up to 37 segments in the unique holotype, the 

 longest segments being two and a half times as long as their median widths; the elongate 

 distal segments of the oral pinnules are not conspicuously expanded or spinous at their 

 distal ends. 



Description. The centrodorsal is rounded conical with a smooth dorsal pole. The 

 basal diameter is about 2 mm. The cirrus sockets are arranged in 15 fairly distinct 

 vertical rows. 



The cirri are about XL with 24 to 37 segments. Only a single peripheral one 

 remains intact. The cirri of the second row have about 32 segments, of which the third 

 is longer than broad and somewhat constricted in the middle, wider at the distal end 

 than the proximal. The fourth and fifth segments are the longest, about two and a half 

 times as long as their median width. The following segments decrease in length; the 

 tenth is less than twice as long as broad and the twentieth and those following are as
