difference to which I am inclined to attach little systematic value, the differences 

 between St. sivakopiamis and St. xanthotricha are similar to the differences between 

 St. monilifer and St. hirsutiis. According to Fauvel (1927, p. 119) all the intermediate 

 stages between the latter pair of species are found.

Remarks. These specimens are mostly in bad condition. I can find 



nothing to distinguish them from the northern form. Fauvel (1927, 

 ,.,.,,, ., ,.. J • Fis. 6t,. Flabelli"era 



loc. at.) writes: "A partir du 25^ setigere une ou deux grosses soies ^^J:^^.^^ Elongated 



composees ou pseudocomposees, etc." Surely 25'- is a printer's error papilla. 



for 2"-'} I figure a papilla of the elongated kind (Fig. 63).

St. 90. 10. vii. 26. Simon's Town, False Bay, South Africa. Basin of H.M. Dockyard. 0-2 m. 

 Gear NH. Two specimens. 



Remarks . The largest specimen measures 25 mm . by 5 mm . including 

 the mucous sheath for 32 chaetigers. The mucous sheath is so thick 

 that the ends of the bristles are embedded in it. There is only a single 

 hook with a strongly curved blade in each neuropodium. The more 

 elongated type of papilla (Fig. 64) has a different form from that 

 usually found in Fl. affinis. 



Willey and Fauvel (1916, p. 451) both regard this species as identical 

 with Fl. affinis. In all the examples of the latter species that I have 

 seen the shape of the papillae is very constant. Therefore, in view 

 of the difference in the papillae already mentioned, I hesitate to unite 

 the two species. I can find no other distinguishing character.
