Dasychone natalensis (Kinberg). 



Branchiomma 7iatalensis, Johansson, 1927, p. 165, with synonymy. 



Dasychone violacea, Mcintosh, 1885, p. 504, pi. liii, fig. 3 ; pi. xxxi A, figs. 7-8 ; pi. xxxix A, fig. 7. 



Saldanha Bay Beach, South Africa, 1926. Four specimens. 



Remarks. This species, easily distinguished by the spirally twisted gill bases and the 

 very numerous short gills with their paired foliaceous dorsal appendages is, according 

 to Johansson, the Sabella natalensis of Kinberg. The largest specimen measures 82 mm. 

 for the body and 13 mm. for the gills. 



Dasychone nigromaculata (Baird). 



Mcintosh, 1885, p. 503, pi. liii,fig. 5;pl. xxxi A, figs. 4-6; 

 pi. xxxix A, fig. 6. 



Branchiomma nigromaculata, Johansson, 1927, p. 162, 

 with synonymy. 



St. I. 16. xi. 25. Clarence Bay, Ascension Island. 7° 55' 15" S, 

 14° 25' 00" W. 16-27 iTi. Gear NRM. Bottom : coral, sand and 

 shell. Eight specimens. 



Remarks. These are all very small specimens 

 measuring about 7 mm. for the body and 4 mm. for 

 the gills. I believe them to be young examples of 

 Baird's species. The body colour is a pale green with 

 eye spots between the rami of the feet. The barbules 

 are splashed with brown. There are only seven gills 

 on each side, and each gill has about five pairs of 

 eyes and six pairs of dorsal stylodes. These are slender 

 and filiform and of unequal size. The bristles and 

 hooks (Fig. 84, a) agree with Mcintosh's figures, 

 except that the broader sort of thoracic dorsal bristle 

 (Fig. 84, b) is more widely winged than as shown by 

 Mcintosh. The character of the dorsal branchial 

 stylodes and the shape of the hook seem to be 

 characteristic.

Hypsicomus torquatus (Grube).

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

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



Remarks. This specimen measures 12 mm. for the body and 9 mm. for the gills. 

 Its most conspicuous character is the brown colouring of the abdominal gland shields. 

 The present material does not permit me to add anything to Augener 's full account of 

 this species.
