They begin abruptly at somite LXXVII but are less distinct than in 

 that species. 



Suriiga Bay, 3,739, 35-65 fms. 



GLYOERID^. 

 Glycera goesi Mgm. 



I am quite unable to distinguish between this species and G. decipicns 

 V. Marenz., under which latter name it has already been recorded in 

 Japanese waters from the Bay of Miya. The examples from the 

 "Albatross" dredgings are all of small size. In some the gills are very 

 regularly developed, in others most irregularly and in still others they 

 are altogether retracted. They come chiefly from moderate depths at 

 the more northern stations. 



Sm-uga Bay, 3,715, 65 fms. ; 3,723, 13-16 fms. ; Sendai Bay and north 

 ward, 3,767, 14-18 fms.; 3,768, 25-27 fms.; 3,771, 61 fms.; 3,775, 

 57 fms. 

 Glycera tesselata Grube. 



This species is widely distriljuted in the Atlantic Ocean, but has not 

 been hitherto recorded from Pacific waters. 



Sagami Bay, 3,698, 153 fms. 

 Glycera alba Oersted. 



Like G. goesi this species is represented, with one exception, by small 

 examples only and the gills are frequently minute vesicles. The 

 tubercle which appears on the parapodium just above the branchia in 

 Malmgren's, but not in Oersted's, figures is absent in all of these speci- 

 mens. 



Sagami Bay, 3,702, 31-41 fms.; Suruga Bay, 3,707, 63 75 fms.; 

 Suruga Bay, 3,740, 65 fms.; North Japan, 3,767, 14-18 fms.; 3,775, 

 57 fms., the latter the only large example taken. 

 Glycera robusta Ehlers. 



The anterior end of the single large example by wdiich this species 

 is represented is interesting from the regular occurrence of small colo- 

 nies of dichotomously branching ciliates between the parapodia. 

 These bear a most striking resembling to the "gills " of G. opisthobranch i 

 V. Marenz. 



Suruga Bay, 3,718, 65 fms. 



ARICIID^. 

 Aricia fimbriata sp. nov. (PI. XXIV, figs. 31-35.) 



A specimen comprising the head and 83 setigerous somites, with a 

 length of 60 mm. and a maximum diameter of 7 mm., is the type of
