EVARNE ATLANTICA. 



about the length of the smooth portion at the tip, which is diagnostic of this form and 

 also of Evarne Normani} The present species differs from the latter, again, in the more 

 tapering extremities of these bristles, and in the closer rows of spines. The spinous tips 

 of the ventral series are somewhat longer than in E. impar, and in this respect approach 

 E. Normani. 



In the typical foot the lower lobe is more pointed and the ventral cirrus longer than 

 in E. impar, so that it projects as far as the tip of the foot. The translucent dorsal 

 bristles (Fig. 31) are considerably longer and less curved than in the typical species, and 

 their rows of spines much closer, the latter character also distinguishing them from 

 E. Normani. The ventral bristles (Fig. 32) approach those of the latter species more 

 closely than those of Evarne Johnstoni, being somewhat shorter than those of E. Normani, 

 which, again, have stronger tips than those of E. Johnstoni.

No scales are present. In all probability they approach those of E. Normani, 

 By the lengthening of the tips of the ventral bristles and their general slenderness 

 this species and E. Johnstoni come near Antinoe and allied forms.
