viz. Fjona trifida, was dredged. Izuka, in his researches in 

 the seas of Japan, found three specie?, but Goniada viaculata 

 did not occur. Tiie reports o£ the German investigations of 

 this family are not to hand, and so no comparisons &c. can 

 be drawn. 



Tlie iiead is a long, bluntly rounded, conical process, witli 

 four short squat cirri, and consists of eight segments, wiiicli 

 are very indistinct in tliis form. The body has, including 

 the head, about eighty segments, and tapers more anteriorly 

 than posteriorly, where it ends in two fairly long tapering- 

 cirri, which are pale and translucent. The colour appears to 

 vary with the sex and with the season. This example is 

 dusky brown throughout, but light touches occur at the bases 

 of the feet and on the sides of the head. For a full descrip- 

 tion of fresh forms see * Monograph of British Annelids,' 

 vol. ii. part ii. pp. 464-6. Tlie feet stand out conspicuously 

 from the sides of tiie body, and are in agreement with those 

 of typical forms. Tiie bristles, however, like the example, 

 are small, but are quite characteristic of the species, being 

 pale in colour, tapering, and thin, the dorsal bristles having 

 straight shafts, with no serrations or terminal pieces, and 

 slightly dilatated tips. The ventral bristles are also pale 

 and have fairly long curved shafts, with slender serrated 

 terminal pieces articulated at the ends. The bristles are 

 arranged fan-wise, and the tips of the posterior bristles, espe- 

 cially the central series of the fan, attain a much greater 

 length. 



The alimentary tract is .'simple, fairly narrow posteriorly, 

 but wide anteriorly, and is easily seen through the thin 

 body-wall. The mouth is ventral, possesses lips, and the 

 anus lies between the two anal cirri already mentioned. 

 The specimen is not mature, but some forms procured of? the 

 S.W. of Ireland had large ova in July. Prof. M'Intosh is 

 inclined to think that Goniada alcockiana, Dr. Carrington, 

 is a variety of this species. 



Genus Glycinde, Fritz Miiller. 

 Glycinde nordmanni, Malmgren, 1866. 



Four very much dried and shrivelled specimens of this 

 annelid were dredged on the 4th December, 1905, at Dabs 

 Voe, in 15 fathoms. Each measures about 2 inches long, 

 but one is very much thinner and more linear than the 

 others, whose bodies taper anteriorly but more gradually 

 posteriorly. The colour is dark brown, resembling that of 

 Ophiodromus flexuosus, and there is little difference in hue
