Leucon. In that case it will fall into the group of species which have a large inner 

 flagellum on the antennule. From all the species of this group it is distinguislied by 

 having the outer rami of the uropods shorter than the first segment of the inner.

I am unable to find any differences of importance by which to distinguish three New 

 Zealand specimens from North Atlantic specimens of this species. They are of small 

 size, an ovigerous female measuring only 2-75 mm. in total length. The armature of 

 the antero-lateral margin of the carapace resembles that found in E. truncatula and in 

 JE. jiifsilla (the distinctness of these two species appears to me doubtful), but the tooth 

 of the antero-lateral angle is a little more prominent, though much less so than in 

 E. nana or E. hisjnda. The second legs have the basis not much shorter than the 

 remaining segments together, and the merus and carpus relatively shorter than in 

 northern specimens of E. truncatula. The terminal spine of the endopod of the 

 uropods is also somewhat stronger.

EUDOEELLOPSIS EESIMUS, sp. n. (Plate VIII. figs. 6-10.) 



Description of adult Female. — Total length 1-75 mm. 



General form much as in E. deformis (Kroyer). Pseudorostrum well-marked, directed 

 upwards with a slight inclination forwards, distal end truncated, posterior corner not 

 produced, length along posterior edge about one-fourth of total length of carapace. 

 Posterior part of dorsal edge of carapace carrying a prominent tooth directed obliquely 

 forwards. Antero-lateral edge coarsely serrated, the teeth becoming lower and more 

 irregular on the upper part, lower part curving backwards and ending in a small tooth 

 defining the antennal notch. The side of the carapace bears, above the middle of 

 its height, a longitudinal ridge which curves upwards to the anterior edge of the 

 pseudorostrum. 



The antennules are more slender than in E, deformis and bear less numerous spines. 

 The outer flagellum, composed of three segments, is shorter than the last segment of 

 the peduncle. The unjointed inner flagellum is equal in length to the first segment 

 of the outer. 



First legs short, reaching beyond the anterior end of the carapace by not more than 

 the length of the last segment, less richly setose than in E. deformis. Second legs 

 also short, with carpus half as long as merus and equal to propodus. 



Uropods short and stout, peduncle about two-thirds as long as the last somite.
