Remarks. I have much hesitation in assigning these specimens to Ehlers' species 

 because the head of the chaetal shafts is more expanded, and the blades (Fig. 33, a) 

 much shorter and stouter than those figured by Ehlers {he. cit.) and by Gravier (1907, 

 p. 20, text-fig. 14). I find two kinds of southern Syllis with long multi-articulate dorsal 

 cirri and bidentate chaetal blades in this collection. One in which the bristles are few 

 (seven to eight), and the chaetal blades are short and broad with a very distinct second 

 tooth ; the other has more numerous bristles and longer and more slender chaetal blades 

 withaslight second tooth. Inboth, the pharynx is rather long, reaching to the I3th-i5th 

 chaetigers and the proventriculus to the 20th-2ist, and the tooth is terminal. 



The forms with the broad chaetal blades I have doubtfully assigned to S. brachycola, 

 and those with slender chaetal blades to S. variegata. In two or three of the examples 

 of S. brachycola the front part of the body is coloured brown, the pigment extending 

 to the dorsal cirri. One of the longer dorsal cirri from the middle of the body has 

 about 45-50 articulations. I figure a head with the pharynx everted (Fig. 33, b). 



Except in the shape of the chaetal blades, these specimens agree with Ehlers' 

 description.
