A well preserved partly grown specimen of this species is in the collection 

 transmitted for study along with that of the Canadian Arctic Expedition. The 

 colour markings are exceptionally distinct, these consisting of large black pigment 

 spots on the dorsal surface of the body and of parallel transverse stripes across 

 the dorsal and upper lateral surface of the proboscis, those just proximad of the 

 tentacles being deepest. The papillae and other external features are typical.
