EUNICIDAE 



■43 



which I believe to be of the same species, they are fully developed. There is the usual 



pair of long slender black carriers. M. I is a pair of simple pincers. M. II has five 



teeth. M. Ill is small and has a large tooth with a very 



small and easily overlooked second tooth below it. J^l^i^in 



M . IV is also small and unidentate. Behind the ' ' carriers ' ' 



is a large roughly cordiform plate which I believe to be 



a support of the "carrier," and not a lower jaw plate. 



I could discover no lower jaw plates. 



Remarks. I cannot with certainty attribute these two 

 specimens to any known species, and I do not, with the 

 material at my disposal, feel justified in establishing a 

 new species. They are very close to and perhaps 

 conspecific with Drilonereis pinnata, Treadwell (1921, 

 p. no) from the West Indies. Treadwell's species has 

 eyes and differs also in certain details of the jaws.

Fig. 53. Drilonereis, sp. Jaws. 



Remarks. A single specimen measuring 12 mm. by 2 mm. without the feet. It 

 corresponds exactly to Fauvel's account except that at the posterior border of the pro- 

 stomium is a couple of very faint minute dots which may represent a second pair of 

 eyes. As Fauvel points out, this species is distinguished from S. nidulphii only by the 

 absence of geniculate bristles from the first two chaetigers. 



This species is quite distinct from the S. egena (Ehlers), also from Simon's Town. 



Staurocephalus rubrovittatus, Grube. 



Fauvel, 1923, p. 445, fig. 177 a-l. 



Stauronereis nihruviltata, Augencr, 191S, p. 376. 



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

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



Remarks. A single colourless example of this species. It is characterised by the 

 presence of capillary bristles only in the notopodium and by the long hair-like pro- 

 longation of the supports of a number of its jaw plates in the middle of the row.
