NEPHTHYDIDAE m 



The feet (Fig. 39, d) are very like those of A^. kergiielemis and Leptonereis loxechini. 

 The notopodium has two conical dorsal languets of about the same size, between which 

 is a third very small languet in contact with the bristles. This third languet disappears 

 in the posterior feet. The neuropodial chaeta sac has two unequal lips, the anterior 

 rounded and the posterior longer and conical. The ventral languet is broader and 

 blunter than those of the dorsal branch. The dorsal cirrus extends for about half its 

 length beyond the end of the upper dorsal languet and the ventral cirrus is the same 

 length as the ventral languet. The dorsal bristle bundle contains homogomph spinigers, 

 the upper ventral bundle homogomph spinigers and heterogomph falcigers and the 

 lower ventral bundle a single heterogomph spiniger and heterogomph falcigers. 



There is a pair of long pygidial styles at the end of the body. 



Remarks. In its general appearance and in the shape of its feet this species is close 

 to N. kerguelemis. The intermediate dorsal languet is not so fully developed ; there are 

 no paragnaths in the maxillary ring and there is a single heterogomph spiniger in the 

 lower ventral bristle bundle. I have not been able to find any heterogomph spinigers 

 in A^. kerguelensis. 



I have named this species after Prof. A. C. Hardy, the resourceful second in command 

 of the expedition.

St. 283. 14. viii. 27. Off Annobon, Gulf of Guinea. 75 to i mile N 12° E of Pyramid Rock, 

 Annobon. 18-30 m. Gear DLH. One specimen. 



Remarks. The specimen from St. 283 corresponds in detail to Langerhans' descrip- 

 tion and figures. The very sparse paragnaths are distinctive. The colour markings are 

 similar to those figured by Augener for his C. rolasiensis, which does not seem to be 

 separable from this species. The specimen is atocous, and I have not sufficient material 

 to add anything to the already published accounts of this species.
