136 DISCOVERY REPORTS 



Specific characters. The largest specimen measures about 33 mm. in length for 

 about 70 chaetigers: Augener records a specimen measuring 60 mm. in length for 87 

 chaetigers. The arrangement of the paragnaths is as follows: (I) one, or two or three in 

 a longitudinal row; (II) rather small curved clusters; (III) a transverse cluster; (IV) 

 curved clusters; (V) none or one; (VI) a pair of small usually cruciform patches; 

 (VII) and (VIII) a somewhat irregular band of two or three rows. 



In the notopods there is a pair of conical, subequal languets and a long dorsal cirrus 

 extending for more than half its length beyond the foot. The ventral ramus has a blunt 

 ventral languet and a short ventral cirrus. In the hinder region the languets are more 

 slender and pointed. I find nothing distinctive in the bristles. 



Remarks. This species has been recorded from Chile and Peru, and from West 

 Africa and the Cape. It is therefore not surprising to find it at Gough Island. 



Nereis jacksoni, Kinberg. 



Fauvel, 1932, p. 97, with synonymy. 



Occurrence. St. 929, New Zealand (10). 



Specific characters. Body very slender and elongate. There is no notch between 

 the prostomial tentacles. The paragnaths are arranged as follows : (I) none ; (II) curved 

 rows; (III) a transverse patch; (IV) crescentic patches; (V) none; (VI) on each side a 

 small group of minute paragnaths; (VII) and (VIII) a single row of about seven widely 

 spaced paragnaths. 



In the feet the dorsal ramus has two conical languets and a dorsal cirrus longer than 

 the foot. The ventral chaetal lobe is rounded and there is a large blunt ventral languet. 

 In the hinder region the dorsal languet is much reduced. 



The ventral heterogomph falcigers have curved and ciliated end-pieces. In the middle 

 and posterior regions the notopod carries one or two homogomph falcigers with bi- 

 dentate or tridentate end-pieces. 



Remarks. The relation of this species to N. kauderni is discussed by Fauvel {loc. cit.). 

 It seems to me that the grounds for separation are very slender. 



Nereis eugeniae (Kinberg). 



Ehlers, 1897, p. 67, pi. iv, figs. 94-105. 

 Monro, 1930, p. 104. 

 Occurrence. St. 652 (2); WS 583 (10); WS 796 (2); WS 811 (10); WS 824 (i); WS 834 (10); 

 WS 866 (4). 



Specific characters. Size up to about 170 mm. by 3 mm. without the feet for 125 

 chaetigers. The eyes are not very distinct. The arrangement of the paragnaths is as 

 follows: (I) none; (II) a small subtriangular patch; (III) absent, or a few sparse para- 

 gnaths ; (IV) an oblique distichous mass ; (V) none or one ; (VI) on each side a small 

 patch of three or four paragnaths; (VII) and (VIII) either absent or a single sparse 

 rather irregular row. 



In the anterior region the dorsal ramus of the foot has a pair of triangular languets, 

 the upper longer than the lower, and a very small chaetal lobe. The ventral ramus has a
