THE MYSIDS 



69 



outer uropods equal in length; inner uropod without any 

 spines on the lower and inner margins. 



Length of the type and only specimen, a female, 3 

 mm. 



REMARKS 



The exact systematic position of this species must 

 remain uncertain until male specimens are available for 

 examination as to the form of the pleopods. The author 

 thinks, from a comparison with known forms, that the 

 species will eventually find a place in the Tribe Mysini, 

 near to such pelagic genera as Anisomysls,Cryptomysis, 

 and Idiomysis. The most striking feature of the species 

 is the quite peculiar and unique character of the eyes. 



The latter resemble, in a superficial manner at any 

 rate, the eyes of some of the Euphausians, such as 

 Nematoscelis, ThysanoCssa, or Stylocheiron, in having 

 the cornea divided into distinct dorsal and ventral parts. 

 In Carnegieomysis, however, the two parts are separat- 

 ed by a groove in which corneal elements are absent. 

 It is a type of eye which is developed in response to a 

 pelagic habit of life and is probably closely similar in 

 general structure, though even more developed than, the 

 eye of Euchaetomera and allied genera. There is no 

 other my Sid with which it can be confused in the charac- 

 ter of the eyes. Apart from the eyes, the most outstand- 

 ing characters are the form and size of the antennal 

 scale, and the shape and armature of the telson.
