NO. 1703. SOME POLYCff^TOUS ANNELIDS— MOORE. 139 



Family ARICIID^. 



SCOLOPLOS ARMIGER (Muller) Blainville. 



Off Beacliy Island, between Flint Island and Cape Mugford, 

 August 22, 80 fathoms, soft mud ; 1 mile north of Battle Harbor, 

 September 14, 50 fathoms, fine sand. 



Small incomplete sj^ecimens, representing the anterior end only, 

 from these stations agree very closely with the published descriptions 

 and figures of this species. They are much contracted and the an- 

 terior branchia3 are very minute, but appear to begin on somite XIII 

 in all cases. Several of the anterior segments are lightly banded on 

 the dorsum with brown ; S. acutuin Verrill is very closely related, if 

 not, indeed, identical, with this northern European species and occurs 

 in southern New England. Webster and Benedict regard it as the 

 same as S. armiger which they report from Eastport. 



Family CIRRATULID^. 



CIRRATULUS CIRRATUS (Muller) Malmgren. 



Shoal Tickle, southeast of Nain, August 15. A single much con- 

 tracted specimen about 30 mm. long and filled with eggs. There are 

 seven or eight conspicuous eye-spots on each side of the prostomium, 

 arranged in a pair of slightly curved oblique lines, converging, but 

 not meeting, in front. This is another of the species reported by 

 Packard. 



CH.ffiTOZONE SETOSA Malmgren. 



Off Beachy Island, between Flint Island and Cape Mugford, 

 August 22, 80 fathoms, soft mud. 



Four small imjDerfect specimens 8-15 mm. long agree with Malm- 

 gren's description and figures except that they possess a pair of 

 long, stout tentacular cirri (sometimes called palpi) and a larger 

 number of branchial filaments (notocirri). The posterior spines are 

 also more slender and elongated than in the adults. In these re- 

 spects they agree exactly with examples found at Eastport by Web- 

 ster and Benedict. The tentacular cirri of many Cirratulidse are 

 known to be extremeh^ caducous, and this, together with the fact that 

 many become epitokous (recently discovered by Caullery), has caused 

 much confusion and unnecessary multiplication of genera. 



Family AMPHAEETID.^. 



SABELLIDES BOREALIS Sars. 



Halfway between Cape Mugford and Hebron, August 23, 60 

 fathoms, mud and sand. 



A fine specimen, 60 mm. long and more than 3 mm. in maximum 

 width ; segments 29, 14 setigerous. Notocirri begin on XIX and ex-
