This species has previously been gathered off the west coast of Ireland "at depths of from 700 to 1000 fathoms" at five stations "but very few specimens were found on each occasion". Wolfcnden's specimens, which on account of the different shape of the genital somite (PI. XXXV fig. 3) cannot with security be referred to the same species, were gathered under tlie equator ca. 20° L,. W. (depth 3000 m.) 53. Euchaete Hansenii n. sp. (Text-figs 52 a—b.) Description. Size: 8-9 mm.; anterior division 65 mm.; urosome 2-4 nun. The shape of the body is like tliat of E. norvcgica. The anterior division is 27 as long as the urosome, which is onh- a little longer than the width of the thorax. The proportional length of the abdominal somites is 45, 26, 25. The genital soHiitc is, laterally, more suddenh- convex than in E. Sarsi, and, as in this, the greatest width lies in the proximal part; the genital somite is 1-3 as long as wide, but only i-i as long as deep. The lateral conical process which characterises E. barbala and Farraiii, is wanting. In lateral view tlie geni- tal protuberance differs distinctly from that of E. Sarsi b\- the straight, not concave, anterior process, and by a fairly distinct process behind and above the second one, sometimes indicated in E. Sarsi, which, as usu- ally, rej^resents the posterior border of the vulva. The ventral surface is quite different; the triangular plate in front is divided into three processes; the transverse plate has posteriorly a median incision, on each side of which arc two lobes (text-figs 52 a—b). ~ The antrnuulac scarcely extend to the end of the cephalo-thorax; the appe
