FLABELLIGERIDAE 159 



Tharyx sp. juv. 



St. 30. 16. iii. 26. West Cumberland Bay, South Georgia. 2-8 miles S 24° W of Jason Light. 

 251m. Gear DLH. Bottom: mud and stones. Four specimens. 



St. MS 68. 2. iii. 26. East Cumberland Bay, South Georgia. 17 miles S I E to 8i cables 

 SE X E of Sappho Point. 220-247 m. Gear NCS-N. Eight specimens. 



St. MS 71. 9. iii. 26. East Cumberland Bay, South Georgia. 9} cables E ,; S to 1-2 miles 

 E X S of Sappho Point. 1 10-60 m. Gear NCS-T. Three specimens. 



Remarks. I have given this name to a number of small immature CirratuHds, all 

 more or less in poor condition. The average measurement is about 5 mm. by i mm. for 

 30-50 chaetigers. There is a pair of gills and palps on the ist chaetiger and the gills 

 are continued over the greater part of the body. There are no eyes and no hooks in the 

 bristle bundles. They may be young examples of Th. epitoca.

St. 39. 25. iii. 26. East Cumberland Bay, South Georgia. From 8 cables S 81° W of Merton 

 Rock to 1-3 miles N 7° E of Macmahon Rock. 179-235 m. Gear OTL. Bottom: grey mud. Six 

 specimens. 



St. 45. 6. iv. 26. 27 miles S 85° E of Jason Light, South Georgia. 238-270 m. Gear OTL. 

 Bottom : grey mud. One specimen. 



St. 141. 29. xii. 26. East Cumberland Bay, South Georgia. 200 yards from shore under Mount 

 Duse. 17-27 m. Gear BTS. Bottom: mud. Sixty-five specimens. 



Remarks. An average specimen measures about 18 mm. by 3 mm. without the 

 bristles, and has about 30 chaetigers. This species is close to St.plumosa (O. F. Miiller) ; 

 it differs, however, in that the sigmoid ventral crochets begin on the 3rd instead of the 

 4th chaetiger. 



Stylarioides swakopianus, Augener. 



Augener, 1918, p. 433, pi. vii, fig. 234, text-figs. 61 and 62. 

 Stylarioides xantliotricha, Ehlers, par fim, 1908, p. 119, pi. xvi, fig. 2. 



St. 4. 30. i. 26. Tristan da Cunha. 36° 55' 00" S, 12° 12' 00" W. 40-46 m. GearDL. Bottom: 

 stones. Four specimens. 



Remarks. Of these specimens all except one are fragments: the complete specimen 

 measures 33 mm., without the tail, by 4 mm. ; the tail measures 6 mm. There is no need 

 for me to recapitulate Augener 's arguments for separating this, the shaggy-skinned 

 form, from St. xanthotricha . I am still rather doubtful if the two forms are specifically 

 distinct; and both are very close indeed to the European St. moiiilifer. 



Except in the matter of the diff'erence in the number of bristles forming the cage, a
