The occurrence of an example of this species in 600 fatlioms in 

 the Faroe Channel is certainly most interesting. The specimen 

 agrees in minutest details with the figures of Brady and Gies- 

 brecht in mouth-organs, in the 1st and following feet, Giesbrecht 

 (figs. 30 and 31) ; and above all in the characteristic and 

 remarkable fifth foot of female (Brady, fig. 12; Giesbrecht, 

 fig. 25). The single type was taken by the ' Challenger ' in 

 2650 fathoms in the South Atlantic (lat. 36° 44' S., long. 46^ 

 16' "W.)j while that figured by Giesbrecht was from 1800 metres 

 in the tropical Pacific (lat. 3° S., long. 99° W.) ; and now it 

 turns up in the Faroe Channel. It would be difiicult to find a 

 case which demonstrated more completely the vast range over 

 which those animals may be distributed whicli find an equalized 

 temperature in the depths of the ocean. The free-swimming 

 life of the Calanoida of course conduces to their wide distribu- 

 tion, and that they have very wide distl^bution is also proved by 

 the many other instances of hitherto sujiposed southern forms
