Occurrence. St. 27 (12 juv.); 30 (7); 144 (numerous juv.); 366 (2); 456 (2); 474 (i); WS 33 

 (4Juv.);WS2is(i);WS8s6(i). 



Specific characters. The largest specimen is incomplete and measures 127 mm. 

 by 4 mm. for 130 chaetigers. The prostomium is pointed, conical. Ventrally the second 

 buccal segment is involved with the mouth. The pedal lips are short and rounded and 

 there is no increase in size of the hinder lip in the posterior region. In the front region 

 the bristles consist of slender bordered capillaries and compound crochets. The latter 

 have a wide independent flange below the pseudo-articulation. Farther back, usually 

 between the 20th and 30th chaetigers, the compound crochets are replaced by simple 

 crochets, and the bordered capillaries disappear. Their place of disappearance is vari- 

 able, but in adult specimens it appears to be in the neighbourhood of the 70th chaetiger. 



As regards the upper jaws, M. II have four teeth, M. Ill and M. IV are unidentate 

 and there is often an accessory M. V. 



Remarks. I have examined the original specimens of Mcintosh's kerguelensis, 

 Grube, and in my opinion they belong to this species. Benham remarks that the simple 

 crochets of his specimens more closely resembled Mcintosh's figure (pi. xviii A, fig. i) 

 of those of L.japonica than his figure (pi. xvii A, fig. 18) of the crochets of L. kergue- 

 lensis. I have examined the toothed heads of a series of simple crochets and I find them 

 very variable in appearance, partly, I believe, as the result of wear. Mcintosh's figure
