Confined to the Antarctic area and reaching exceptional development at 

 Station 38. Several typical specimens at Station 3(5 (2.216 fms.). The occurrence 

 of this cmious but distinctive little form, so far away from its original locality in 

 British seas, and in such deep water, is noteworthy. No spinous examples (our 

 var. bispinosa, H.-A. & E. 1913, CI. p. 129, pi. xiii, fig. 4) occur, although the 

 variety is recorded by Sidebottom from the East Coast of Australia, in 465 fms. 

 (S. 1918, FECA. p. 256, pi. vi, fig.s. 18. 19), the type being absent in that locality.
