Here is auotlier species of very wide distribution. Described 

 from Mediterranean specimens, it was found by Sir J. Murray 

 in the ' Triton ' Expedition of 1882, in the Faroe Channel down 

 to the depth of 500 fathoms, and now Giesbrecht announces it 

 as having been collected in the Antarctic Ocean by the Belgian 

 Antarctic Expedition of 1897-1899.

 An Onc<sa taken by the 'Triton' in the Earoe Channel, and 

 which I had sent to Prof. Sars marked " Onccea media ?," was 

 sent back marked in his own writing " ? Onccea media,'''' so that 

 it must be regarded as a doubtful inhabitant of the locality 

 given.

 A single specimen in the Earoe Channel at a depth of 

 600 fathoms. Griesbrecht's type specimens were taken in the 

 tropical part of the Pacific Ocean down to 4000 metres. Next 

 it was taken in the tropical Atlantic (Gulf of Guinea), and now 

 it turns up in the cold area of the Earoe Channel. Had it been 

 found at great depths in the Gulf of Guinea, we might have 

 supposed that though living over so large a range, it yet inhabited 

 w^ater of nearly equal temperature ; but Mr. Scott tells us that 

 the specimens which came under his observation were taken at 

 various depths, ranging from the surface to 360 fathoms. It is 

 possible that these may be closely allied species confused, but 

 the posterior antennse and posterior foot-jaws of the female are 

 very remarkable.
