Tempepature: 17.^5, mean of 47 obs., max. 27.5, min. 8. 



Salinity: 35.4s, mean of 31 obs., max. 37.04, min. 32.5i. 



Plankton-type, Noted from the Mediterranean. As this spe- 

 cies has been seen W. of S. Africa, it probably enters the Atlantic 

 W. of the Cape of Good Hope. In the northern hemisphere it has 

 been only rarely mit with in the Sargasso Sea. The principal areas 

 of distribution are the Antilles and Florida Currents and from 40° 

 N. 65° W. to the Azores and the European coast to about 50° N. 

 Beyond this limit rare specimens may drift to 60° N. The abundant 

 occurrence in September 1899 at 57° is therefore a remarkable ex- 

 ception. — S. (D.)
