Expressed in Bergstrom's formula the tentacular segments are as follows:

 papillae.

 a. Head. b. Middle foot. c. Heterogomph bristle, d. Heterogomph bristle. 



The feet (Fig. 22, b) are bilobed, and the dorsal cirri are large and cordiform, almost 

 as broad as long, and sometimes apparently asymmetrical. The ventral cirri are about 

 one-third the size of the dorsal, rather asymmetrical and with blunted ends. The 

 bristles (Fig. 22, c and d) are remarkable. They are very strongly heterogomph, and 

 the "hilt" ends in a large hook, below which is the articulation for the very small deli- 

 cately hirsute blade. The pygidium consists of a simple rounded lobe. 



Remarks. I believe these markedly heterogomph bristles to be distinctive of this 

 species, for I know no Eulalia with chaetae at all resembling them.
