76 DISCOVERY REPORTS 



Remarks. Bergstrom has made this species the type of a new genus, Sieggoa, on the 

 ground of the foliaceous character of the ventral cirrus of the second tentacular seg- 

 ment, the absence of bristles in this segment, and the presence of a notopodial aciculum 

 in the third tentacular segment. The species is easily distinguishable by the long and 

 comparatively narrow dorsal cirrus.

St. 2S3. 14. viii. 27. Off' Annobon, Gulf of Guinea. -75 to i mile N 12° E of Pyramid Rock, 

 Annobon. 18-30 m. Gear DLH. Ten specimens. 



Remarks. Ten specimens with very long and narrow dorsal cirri. The ventral cirrus 

 of the second tentacular segment is moderately thickened and flattened, and betrays no 

 trace of border. The three tentacular segments are clearly separated. Augener (1918, 

 p. 174) does not figure the ventral cirrus of the second tentacular segment of his Steggoa 

 microcephala (Clap.) from the Gulf of Guinea, and from his description his S. micro- 

 cephala is scarcely to be distinguished from this species. Augener 's Eulalia viridis var. 

 capemis, Schm. from South-west Africa differs in having much broader dorsal cirri.

 Jason Light to 4 miles N 39° E of Jason Light. 120-204 m. Gear OTL. Bottom: mud. Two 

 specimens. 



St. 149. 10. i. 27. Mouth of East Cumberland Bay, South Georgia. From 1-15 miles N 76!° W 

 to 2-62 miles S 11° W of Merton Rock. 200-234 m. Gear OTL. Bottom: mud. One specimen.

 Gear DLH. Bottom: mud, stones and gravel. One specimen. 



St. 190. 24. iii. 27. Bismarck Strait, Palmer Archipelago. 64° 56' 00" S, 65° 35' 00" W. 315 m. 

 Gear DLH. Bottom : stones, mud and rock. One specimen. 



Description. The average size is about 100 mm. by 4 mm. including the feet and 

 the number of chaetigers is about 300. The body is long and vermiform and only 

 slightly tapered at the ends. The body colour is a pale green with large segmental trans- 

 verse bands, sometimes interrupted in the mid-dorsal line. 



The feet and cirri are either dark brown or dark green. The prostomium (Fig. 22, a) 

 is roughly rectangular in shape, and the eyes are set well back ; these are oblong with 

 crystalline centres. There are five tentacles, and the median is set in front of the eyes. 

 The cirrus of the first tentacular segment is about half the length of the dorsal cirri 

 of the remaining tentacular segments. These cirri, when laid along the back, reach to the 

 9th segment. 



The ventral cirrus of the 2nd tentacular segment is slightly flattened and a little longer 

 than the cirrus of the ist tentacular segment. The remaining tentacular cirri are all 

 digitiform.
