NEREIS (NEREILEPAS) FTJCATA. 337 



anterior. Ventral lobe tongue-shaped. Ventral cirrus extends a little beyond the tip of 

 the foregoing lobe. In the superior division of the foot the bristles have long, tapering, 

 spinous tips, and at the lower edge of the fascicle are a few with stouter shafts and shorter 

 tips. In the inferior division the upper series consists of those like the foregoing, then 

 intermediate forms, and inferiorly a dense group of bristles with short tips (heterogomph). 

 The change in the feet of the epitokous female begins in the twenty-first foot as a 

 slight enlargement at the inner border of the ventral cirrus. A similar process appears 

 at the inner base of the dorsal cirrus of the twenty-sixth or twenty- seventh foot. These 

 lameilaB increase to the sixtieth foot and again diminish. Coincident with these a small 

 lamella occupies the posterior surface of the inferior setigerous process. In one specimen 

 the bristles retained the normal form, yet the ova were nearly ripe. Ehlers observes that 

 the change in the feet of the epitokous male begins in the seventeenth foot.
