COPEPODA CALANOIDA FEOM THE FAROE CHANNEL. 131> 



which 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 interesting case of distribution is that oi Amallo^ 

 pJiora magna, T. Scott. This was described by Prof. G. O. Sara 

 in his account of the Crustacea obtaiaed by Nausea in his 

 Arctic voyage, under the name Scaphocalanus 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 (Gulf of Guinea) in only 

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

 Scolecithrix cristata from the North, but not arctic, Pacific 

 Ocean, lat. 35° N., long. 125° W.
