the latter the colour, the tentacles and cirri, the head, 

 feet, and their appeiidaj^es as the bases for classification. 

 Apstein, again, forms his two main groups on the structure 

 of the Ijristles, subdividing by aid of the structure of the 

 feet into eight genera, viz. : Alciopa, A.Herope, Vanadis, 

 Greefia., CaU'izotiella, Coryiiocephalus, Rhynchonerella, and 

 Callizona. It is noteworthy that almost all were found either 

 over or in the midst of very deep water, probably in the 

 line of the Gulf Stream. The group is closely allied to the 

 IMiyllodocidae, and some make it a sul)faraily of the latter. 



The first of these is Vanudis formosa, Claparede, a com- 

 paratively large species measuring 30 cm. in length, with a 

 breadth of 5 mm. and two hundred and twenty segments. 

 Female with four seminal pouches. It was procured on the 

 West Coast of Ireland in the mid-water trawl in deep water, 

 though also in 5 fathoms [Southern). The second is 

 Greejia reynaudi, Audouiu & Edwards, also a widely dis- 

 tributed form in the great oceans. It occurred both in 

 mid-water and at the surface over great depths. The third 

 is Ccdllzona anyelini, Kinberg, procured in the tow-net near 

 great depths. Southern identities this form with C. (jrubei. 

 The fourth is CaUizona setosa, Greef, captured at the sur- 

 face near a depth of 480 fathoms. The fifth is CaUizona 

 nasula, Greef, obtained in the mid-water trawl between COO 

 and 700 fathoms. 



In the family of the Eunicidte Maiyhysa fallax, Marion & 

 Bobretzky, was found under a stone at Bananagh, Blacksod 

 Bay {Southern). Elsewhere it occurs at Marseilles {Marion 

 i^ Bobretzky) ; Dinard, France (Dc <S/. Joseph). Marion and 

 Bobretzky observe tliat the compound bristles with the bifid 

 tips differ from those of M. sunyuinea, and that the dental 

 apparatus also diverges from that of the latter species, in so 

 far as six denticulations occur on the maxilla?. Southern 

 notes four ventral cirri on the anal segment and three spines 

 in the ventral division of the foot. De St. Joseph found 

 his examples in the dredge, and with a coloration ap- 

 proaching that of Lysiilice ninetta. They were small, viz., 

 15 mm. in length. Its bristles resemble those of Murphy sa 

 belli, but it differs in regard to the branchiae and in the 

 form of the head. 



Armandia flag ellif era, one of the Opheliidai, was captured 

 in a tow-net at night near the entrance to Ballynakill 

 Harbour ; dredged in 11 fathoms in mud, Galway Bay
