are longer than the third pair by reason of having their fifth joint 

 as long as the fourth. The fifth pair are scarcely at all spiny, but 

 setose like the fourth, and in length subequal to the third, having 

 their fourth and fifth joints slightly shorter and the sixth a little 

 longer than the corresponding joints in that pair. 



The limbs, as preserved, are pale, with broad orange bands". 



Size: The specimen figured in dorsal view measures 31 mm. from 

 tip of rostrum to hind margin, with a breadth of 26.5 mm. just 

 below the lowest of the three lateral spines- The second speci- 

 men figured was rather smaller. A third is a little larger. 



Locality: Cape Natal Y. by E. (approx.) 24 miles. Depth, 

 440 fathoms. Bottom, mud. 



The specific name is given in token of regard for Captain 

 Turbyne, whose valuable services, first on board the " Medusa," 

 then at the Marine Station, Granton, Edinburgh, subsequently at 

 the Millport Marine Station, and of late years at the Cape, have 

 been highly appreciated by all concerned with marine zoology-
