The length of the prostomium (fig. 1) is about equal to its great- 

 est width, which is at the level of the posterior pair of eyes. The 

 median cleft is not very prominent, and the apices are rounded with 

 no trace of pointed peaks. The posterior pair of eyes are large and 

 prominent, the anterior pair equal to these in size but because of 

 their position on the sides of the prostomium are barely visible from 

 above. 



The cirrophore of the median tentacle is very large and about 

 one-third to one-fourth as long as the style. The latter tapers only 

 very gradually toward the apex, but suddenly narrows and ends in 

 a long slender terminal filament. The cirrophore is colored a dark 

 brown and this color is continued on to the style, becoming more 

 intense toward the end. The extreme apex of the style and the ter-

minal filament are colorless. The lateral tentacles resemble the 

 median in outline, but are lighter in color and the narrowing to form 

 the terminal filament is much less marked. They are slender and 

 very short, hardly longer than the cirrophore of the median ten- 

 tacle. 



The left palp is lost. That on the right side is colorless, not very 

 stout and extends about as far as the median tentacle. The tentac- 

 ular cirri resemble the lateral tentacles in form and color. 



The body in general is faintly tinged with brown, but there is very 

 little definite pigmentation. On the third somite are short transverse 

 bands in the mid-dorsal line, and these are repeated in subsequent 

 somites up to the ninth, becoming much broader in the latter somites
