specimens represent an earlier stage still, and serve to show 

 by tlieir general appearance how little really separates the 

 genus from such forms as Lichenopora. If there were not such 

 good reason to regard them as but a young stage of a branch- 

 ing form, they would fall naturally into the connecting genus

Two very distinct forms, the one including seven specimens, 

 elongated, iinger-like, not branching or proliferating, rising 

 from a very thin pedicel ; a thick firm cortex, which is of dark 

 colour in strong spirit. The central parenchyma contained 

 numerous embryos in one of the specimens. The other group 

 is composed of much narrower stems, generally rounded, but 

 tending to become palmate, profusely branched ; the cortex is 

 thin and flexible, and the colour a pale brown in strong spirit ; 

 ten to twelve specimens of this form occurred. 



One specimen belonging to the first form appeared to have 

 lived free and unattached ; and the deeply constricted condition 

 of another of the same series of specimens appears to indicate 

 that tlie distal ends of such colonies may become detached in 

 life by natural fission. 



Anthozoa. 

 PeacMay sp. 



This genus appears to be not uncommon in the Arctic seas 

 (cf. Liitken, ' Arctic Manual and Instructions ') ; but draw- 

 ings taken on the spot are required for satisfactory identifica- 

 tion of the species. 



Two specimens in spirit occur in this collection, one 

 contracted, and the other expanded but injured, each 

 51 millim. in height. Column cylindrical, height about 

 the same as breadth, tapering slightly to posterior end, which 

 is rounded and has an orifice ; the margin bears the single 

 cycle of tentacles ; no apertures on surface, but minute 

 warts (?) in fine longitudinal ridges ; colour dull flesh-tint at 

 present. Tentacles apparently in one cycle on margin, few, 

 short, thick, blunt ; of pale flesh-colour on external, cream- 

 coloured on oral aspect. Disk flat, cream-coloured. Margin 

 of mouth thrown into a complicated system of several deeply 

 separated projecting tentaculoid lobes (conchula) of a decided
