670 SUBANTAECTIC ISLANDS OP NEW ZEALAND. [Crustacea. 



has recorded it from Port Phillip, Victoria, and, according to Thiele, the specimens 

 collected by Dr. Willey in the Friendly Islands and at New ^pritain also belong to 

 this species. In his report on the Leftostraca collected by the " Discovery," Thiele 

 states that N. longicornis, var. magellanica, has been found at McMurdo Strait, 

 and that it was also taken by the German Antarctic Expedition at the winter quarters 

 at Gaussberg. The species is very close to N. bipes, the northern form, and Dr. 

 Willey's specimens were referred to N. hi'pes by Mr. Stebbing. Ohlin also placed 

 in this species specimens gathered in Magellan Straits ; these, however, Thiele con- 

 siders to be a variety of N. longicornis, distinguishing it under the name magellanica. 

 In the Berlin Museum there are specimens from Cuba which Thiele also refers to 

 this species, considering them, however, to represent another variety, which he has 

 named soror.
