as they show, as do my own investigations in some fjords in Greenland 

 last summer (1912), that the species is in reahty far more widely distri- 

 buted than has previously been known.

This species has been included here, although it does not originate 

 from Dr. Nordmann's collections; but Porsild has given some speci- 

 mens to our Museum, which were obtained, Oct. 1910, from drift wood 

 at the Danish Arctic Station in Godhavn, Disco. The species is new to 

 Greenland; hitherto it has been recorded only from Arctic Seas (teste 

 HoEK in Nord. Plankton) from Spitzbergen (Weltner, Fauna arctica, 

 vol. 1, 1900). 



Cirripede nauplii and Cypris stages have been taken in several places 

 (see list of localities).
