the posterior margins of the basos joint of the sixth and seventh 

 pair of legs. 



It is probable, therefore, that a distinct species is figured by 

 Buchholz in the plate referred to. 



This species has been recorded from the shores of Arctic America 

 (Felix Harbour, Igloolik), Greenland, Spitzbergen, Finmark, and 

 Norway.

Coll. Feilden : Discovery Bay, at 25 fathoms, one specimen ; Floe- 

 berg Beach, one specimen. 



Both of the specimens collected are in an imperfect condition : 

 one is, I believe, an adult female ; the other is a younger animal. 

 The length of the larger specimen (that collected in Discovery Bay) 

 is about 10^ lines (20 millims.). 



Halirages fulvocinctus has been recorded from the coasts of Green- 

 land, Spitzbergen, and Finmark.
