interesting problems yet to be solved by zoogeographers, but, I 

 think, we shall have to wait a long tirne, before this intricate 

 question can be satisfactorily settled. 



Särs' descriptions of the species are so exhaustive that 

 I have nothing to add to them. Speciinens preserved in a mixture 

 of formol and alcohol still exhibit the bright red colour of 

 the body. The eyeseales, the earapace, the antennse and the 

 legs are whitish. 



Length of greatest specimen (a female) 62 mm. 



or from the tip of the antennal scale to that of the 

 uropod 78 ram. 



The largest specimen which Särs measured in this way 

 vvas 85 mm. long. It was obtained in the Southern Ocean. 



Amblyops G. O. Särs 1872. 

 Amblyopsis G. O. Sars, 1869 (preoccupied). 



This genus was first brought to the notice of the scientific 

 vvorld in 1869 by G. O. Sars, in his »Unders0gelser över 

 Christianiaf jordens Dybvandsfauna», to receive a Mysidean 

 closely allied to Psrudomma, and first mentioned in 1868 by 

 the great Xorwegian carcinologist's illustrious father in his 

 »Fortsatte Bemserkninger över det dyriske Livs Utbredning 

 i Havets Dybder>^ under the name of Pseudomwa ahhreviatum 

 G. O. Sars. In Heft 2 of his Carcinologiske Bidrag til Norges 

 Fauna G. G. Sars has more fully described and figured this 

 species, which was obtained by him in depths ranging from 

 100 up to 300 fathoms at several places on the coast of 

 Norway. e. g. ofF Lofoten, in the Hardanger- and Christiania- 

 Fiords. The same author afterwards added to this genus, in 

 his report on the Challenger Schizopoda, another form from 

 the Southern Ocean off Crozet Islands, of which species, how- 

 ever, only a single specimen — an adult male — was obtain- 

 ed. To my great surprise. I rediscovered five specimens, viz, 

 four males and one female, of this species from a station of 

 the Swedish Arctic Expedition, 1900, together with a number 

 of the bathypelagic Borcomy^is scypkops. I am unable to
