general locality, together with a list of the station numbers at which 

 each species was taken. 



All of the species contained in the collection have been determined 

 and, with the exception of the families Sahellkhc and Serpulidce. and 

 several species of other families which have been reserved for further 

 study and comparison with material not now available, are recorded 

 in the follo'^nng list. A large number of species, either new or hitherto 

 unreported from that region, are added to the Japanese fauna. One 

 of the surprises of this study has been the very small number of Maren- 

 zeller's species which were taken by the "Albatross." Of the species 

 previously known most of them belong to the circumboreal fauna, 

 several were dredged by the "Challenger" at points off Japan, ajid the 

 others have l^een recorded from various more or less distant parts of 

 the world. As Marenzeller has in preparation an account of the geo- 

 graphical relations of the Jaj^anese Polycha^ta, nothing more need be 

 said on this subject. The general results remind one of those at- 

 tained by ^'errill along the Gulf Stream slope of North America. 



POLYNOID^. 

 Harmotlioe imbricata (Linn.) Mgrn, 



The setae of the two small specimens taken are colorless and the neuro- 

 podials slender. 



Totomi Sea, 3,715, 65 fms.; Totomi Sea, 3,725, 12-13 fms. 

 laenilla subfumida (Grube). 



This is one of the very few Philippine species which have been 

 found on the coast of Japan, from which it has not been hitherto 

 recorded. 



Sagami Bay, 3,702, 31-41 fms. 

 Polynoa semierma sp. nov. (PI. XXIII, figs. 2, 3.) 



Form long and slender, composed of 64 somites and measuring 42 

 mm. in length and 3 mm. in breadth, exclusive of parapodia. 



Unfortunately the prostomium is in a very bad state of preservation 

 and much altered, with all of the appendages, excepting one palpus, lost 

 and only their position indicated by scars. The general shape of the 

 prostomium is much as in Harmothoc, the anterior peaks being well- 

 marked, pointed and widely separated. The left palpus has a length 

 of four times the ^^•idth of the prostomimn and is slender and. regularly 

 tapering. Two pairs of black, very small, circular eyes can be distin- 

 guished, one lateral, about the middle, the other dorsal, near the pos- 

 terior margin of the head. The protruded proboscis bears the usual 

 jaws, but the papilla? have been destroyed. It has a length of 3.5 mm.
