DISCOVERY REPORTS 



a number of gigantic soft globular vesicles (Fig. 4 c) without an apical papilla. As in the 

 stem-form the ventral bristles are both bidentate and unidentate, the former being more 

 numerous in the middle of the bundle. 



The specimens from St WS 834 present a remarkable appearance, for the whole 

 surface of about the hinder third of the scales is a mass of gigantic round vesicles with 

 a granular structure, each attached to the scale by a narrow base. The specimen from 

 St. WS 221 has much fewer and smaller vesicles, and the only remaining scale on the 

 specimen from St. WS 583 has a few large vesicles. All these structures are at once 

 separable from the much smaller, harder, pyriform and papillated tubercles in the stem- 

 form. 



The largest of the present specimens measures 30 mm. by 5 mm. without the feet for 

 40 chaetigers.

Remarks. Augener, who has seen the type, states that Polynoe vesiculosa, Grube, 

 from the Magellan region is the same as Harmothoe exafithema, and as I regard the 

 present examples as distinctly separable from the latter species I have established a new 

 variety. I rather suspect that Ehlers (1897, p. 14 and 1901, p. 42) had before him 

 examples both of this form and of exanthema, and included them both under the name 

 vesiculosa.

Specific characters. A small species measuring about 15 mm. by 2 mm. without 



the feet for 34 chaetigers. There is a typical harmothoid head with the anterior pair of
