COPEPODA CALATSrOIDA FROM TKE FAROE CHANNEL. 139 



wbich are in these brief notes now proved to reach those out- 

 lying waters of the Arctic Ocean which fill the cold depths of 

 the Faroe Channel. 



Another very iuterestiag case of distribution is that of Amallo- 

 phora magna, T, Scott. This was described by Prof. Gr. O. Sars 

 in his account of the Crustacea obtained by Nansen in his 

 Arctic voyage, under the name Scaplwoalanus acroceplialus ; and 

 he wrote of it as " one of the most characteristic Calanoids of 

 the Polar Sea," and " as one of the commonest forms collected 

 both at the surface and down to 300 metres " ; it, moreover, was 

 among the species from the most northern gathering (lat. 85^ 

 13' N., long. 79° E.). This species Sars has now found to be a 

 synonym of Amallophora magna, T. Scott, the types of which 

 were collected in the tropical Atlantic (Grulf of Gruinea) in only 

 20 fathoms (!), and is recorded by Giesbreeht under the name 

 Scolecitlirioo cristata from the North, but not arctic, Pacific 

 Ocean, lat. 35° N"., long. 125° W.
