examples of S. phimosa were obtained. Again, Canon Nor- 

 man found several of tliis species, but his examples are much 

 inferior to those from British waters. Perhaps it may be 

 said tliat the home of the genus is in North European seas 

 and in the Arctic Ocean, for in Northern Norwegian waters 

 alone the following species abound : — Stylarioides plumosa, 

 S. glauca, S. flahellata, S. Mrsuta, and S. normani. 



In the ' f^hallenger ' Report * the writer notes : " The distri- 

 bution of this family [Chloroemidge] is in some respects note- 

 wortliy, both as regards area and depth. Thus most of the 

 specimens described by former voyagers come from shallow 

 water or between tide-marks, but the explorations of the 

 'Challenger' have carried these peculiar forms to a depth of 

 2500 fathoms, or nearly twice the depth at which the natu- 

 ralists on board the ' Porcupine ' had found Stylarioides glauca. 

 Moreover, the wide distribution of the remarkable inter- 

 mediate type, Bushiella ahyssorum, is interesting in connection 

 with the view that the ancient forms have been gradually 

 driven into the great depths by the more recent types 

 attaining supremacy in the shallower water." Three new 

 species were added to the list by this (' Challenger ') 

 Expedition. 



The specimens of this collection are not very large, the 

 longest being about 2 inches and having fifty segments and 

 the shortest a little over one-quarter of an inch with twenty- 

 four segments. They agree with the description given in 

 Ann. & Mag. Nat. Hist. ser. 8, vol. ii. (December 1908), but 

 the hoof-shaped process does not occur in any. The bristles 

 of the small, probably a young, form are not of the usually 

 golden coloui', but are semitransparent, very slender, and 

 taper to fine points. The transverse markings, however, are 

 quite distinct and characteristic. The surface of the body 

 is very rugose and the bristles of the feet project from it in 

 little clumps. These bristles, like those of the anterior 

 region, are pale, non-iridescent, and translucent. 



The branchise are shrivelled and pale, but in life they are 

 beautiful green-coloured organs, the coloration being due to 

 the blood, which is green, and are protected, like the palpi, 

 by the anterior bristles, which have a forward and upward 

 direction. 



Prof. M'Intosh remarks : — '' It is interesting that the type 

 of bristle seen in this form persists in species from the Indian 

 and other oceans, as shown, amongst others, by Prof. Ehlers
