long, slender, toothed and with a dehcate bidentate tip: more ventrally (Fig. 13, </) they 

 become shorter and more expanded distally. The middle ventral chaetae are all clearly 

 bidentate and only a few at the base of the foot lack the second tooth. The ventral cirri 

 are short and smooth.

 a. Elytron, b. Dorsal bristle, c. Upper ventral bristle, d. Lower ventral bristle. 



Remarks. This variety differs from the typical form in the grooving of the head, 

 the relative length of the palps and in the absence of a long fringe and large tubercles 

 on the elytra. I have retained Evarnella as a sub-genus to include those forms in which 

 there is a clear transition from the very slender, strongly toothed, superior ventral bristles 

 to the broader, shorter, less spinous, inferior ventral bristles. Evarne, Malmgren, being 

 preoccupied, Evarnella, Chamberlin, takes its place. 



Harmothoe (Evarnella) kerguelensis (Mcintosh).

St. 126. 19. xii. 26. 53° 58' 30" S, 37° 08' 00" W. 100 m. Gear N 50 V. Bottom: coarse black 

 sand and mud. (Net touched bottom.) One fragmentary specimen. 



Remarks. A small fragment with a harmothoid head ; it has 16 chaetigers and measures 

 3 mm. by 2 mm. including the feet. All the elytra and appendages are lost, but the 

 bristles agree closely with those of Mcintosh's type. The dorsal bristles (Fig. 14, a and b)
