SCALIBREGMIDAE 163 



Remarks. The body (Fig. 65, a) is long and worm-like, measuring 98 mm. by 5 mm. 

 for 69 chaetigers. There are very numerous slender gills and a pair of short thick 

 grooved palps. 



The bristles of the cage are few and inconspicuous. The bristles of the ist chaetiger 

 are all long and forwardly directed : the ventral bristles are shifted dorsally so that they 

 lie close to the dorsal bundle. The dorsal bristles of the 2nd chaetiger are about half 

 the length of those of the ist, and are also directed forward to form part of the cage. 

 The ventral bristles of the 2nd chaetiger are separated by the normal distance from the 

 dorsal, and are of the characteristic type found throughout the body. They do not form 

 part of the cage. The dorsal bristles of the first four chaetigers are directed forwards. 



Dorsal and ventral bristles are figured by Augener (loc. cit.). The dorsal (Fig. 65,6) 

 are long, thin capillary barred bristles of a transparent white colour; the ventral 

 (Fig. 65, c) are twice as thick, pale yellow, and also end in a fine flagelliform tip. 



The surface of the specimen is beset with numberless long thread-like papillae 

 (Fig. 65, d) with expanded tips. 



The tough, transparent, horny, outer layer of the body is, as Grube states, a thick 

 hyaline cuticle and not a mucous sheath homologous with that in Flabelligera.

Remarks. The specimen from St. 28 is, I think, immature. It is pale yellow in the 

 anterior swollen part of the body and pale green in the rest. There is, moreover, a row 

 of small brown eye spots between the horns of the prostomium : these are absent from 

 the other examples.
