A REVIEW OF THE MYSIDACEA 247 



I. Gordon, who very kindly instituted a search for Cunningham's types 

 and fortunately found them. They comprise four fully adult breed- 

 ing females bearing eggs or embryos in the brood pouch, 24 to 27 mm. 

 in length, in fairly good condition. An examination of this material 

 at once showed that it belonged without any question of doubt, as 

 indeed I had long suspected, to the species described in 1924 by Colosi 

 as Arthromysis chierchiae, which must therefore now be known as 

 Arthromysis magellanica (Cunningham). It is very gratifying to 

 have this hitherto obscure species cleared up. 



I think there is very little doubt that the specimen recorded by Zim- 

 mer (1915b) from the Strait of Magellan as Antarctomysis sp. belongs 

 to the same species. Zimmer's remarks about the eye of his specimen 

 are particularly significant, as the greatly elongate eye is one of the 

 most striking features of this species. 



Unfortunately there were no males in Cunningham's material, so 

 the position of the genus in the classification must still remain obscure. 

 Colosi comments on its superficial resemblance to certain species of the 

 genus Tenagomysis and refers it to the tribe Leptomysini, but I believe 

 its true position is that indicated by Zimmer's identification of his 

 single specimen, i. e., in the tribe Mysini near Antarctomysis.
