io6 DISCOVERY REPORTS 



Remarks. I had much hesitation in basing a new species on a single example, but 

 the complete absence of eyes together with the arrangement of the paragnaths is dis- 

 tinctive. This species is closely related to A'^. eiigenioe: as I have already remarked about 

 that species, there is a tendency for the paragnaths of Groups VII and VIII to dis- 

 appear. When these are absent, the arrangement is similar to that in N. typhla. More- 

 over, the eyes in A'^. eugemae are not so distinct as in most species of Nereis, and I can 

 confirm Ehlers' observation: "Die Augen auf den Seitentheilen der hinteren Halfte 

 des Kopflappens schimmern in der atoken Form oft wenig deutlich durch die Haut 

 durch." I regard A'^. typhla as a A'^. eugemae that has lost its eyes and the paragnaths 

 of Groups VII and VIII.

Remarks. I share Fauvel's doubt as to whether this species is separable from 

 P. dumerilii. I propose, however, for the present to keep Kinberg's name. The two 

 specimens attributed by me (1926, p. 322) to P. dumerilii from the Straits of Magellan 

 and South Georgia should therefore be assigned to P. magalhaensis.
