The longer (PI. II. fiof. 10) have finely striated shafts, which 

 shghtly diminish to the origin ottlie wings, the tapering tip 

 having a well-marked curve, which in the preparations has 

 the convexity forward. The edges of the wings seem to be 

 minntely serrated. In the shorter series (PI. II. fig. II) 

 the tips only project beyond the surface, and the wings are 

 proportionally broader. The presence of the thin anterior 

 lanielhe in these setigerous processes is noteworthy. A 

 papilla under the middle branchial tuft indicates the com- 

 mencement of the series, though it bears no bristles. 



The anterior rows of hooks, which commence on the second 

 setigerous segment, are comparatively long, those toward 

 the end of the bristled region nearly reaching the elevated 

 mid-ventral line. A change occurs after the cessation of 

 the bristles, for, instead of sessile rows of books, uncini- 

 gerous processes are developed beneath a foliaceous lamella 

 after the manner of aPhyllodocid. These lamellae gradually 

 diminish posteriorly, and are minute in the caudal region. 

 The first nncinigerous process and lamella are smaller than 

 those which succeed. At the fourth the nncinigerous lobe 

 is somewhat tongue-shaped with the hook on the dorsal con- 

 vexity, the shorter inferior curve being bare. The lamella 

 is large and reniform, being fixed by its pedicle at the 

 hilus. The minute hooks (PI. III. fig. 3) have the same 

 structure both anteriorly and posteriorly, viz., a proportion- 

 ally large great fang, with five or six teeth in lateral view 

 above it, so that the crown is large, the posterior outline is 

 convex with a deep dimple above the base, which is short and 

 convex inferiorly, whilst the anterior outline has a process 

 beneath the great fang, the prow presenting no peculiarity. 

 These hooks differ so much from those figured by Malmgren 

 that further observations are necessary to ascertain the 

 relationships of the Canadian form. 



5. On the Ampharetidge and Terebellidse dredged by 

 Canon A. M. Norman off Norway. 



The Ampharetidse occurred at various stations, from 33 to 

 44, and ranging to 210 fathoms, and they included Ampha- 

 rete grubei, Malmgren, Atnphicteis gimneri, Sais, Sabellides 

 octocirrata, Sars, Melinna cristata, Sars, M. elisabetha, 

 M'Intosh, and Amage auricula, Malmgren. 



Amongst the interesting Terebellids are a form near 

 Amphitrite grayi, Malmgren, Terebella danielsseni, Malmgren,
