There was no trace of auy external membrane (epitheca) covering this part to be 

 seen in my specimens. The sott parts are entirely contineil to the upper surface of the coral, 

 where they cover as well the septa as the intervals between them. 



The animal is (see tig. 24. 26) single and actiniform like that of the Ulocyathus. The 

 bucal disk, which is stretched over the central hollow part of the coral (fossa calicinalis) so 

 that the interior part of the primary and secondary septa is completely concealed, and which 

 moreover is evenly continued outwards between the septa, shews tolerably coarse radial fur- 

 rows crossed by finer circular ones. The mouth forms an eliptical opening in the middle, 

 larger or smaller according to its greater or less contraction. The lip is thickened and crenu- 

 lated by numerous rounded lobes, which are limited by tolerably deep incisions. From these 

 lobes there descend, to the very bottom of the stomachal canal, the linear convex bucal folds 

 which are all nearly alike developed (none notably larger than the others). 



The tentacles which always proceed from that point where the septa lose themselves 

 in the bucal membrane, are very small, about 50 in niimber, and forming 4 or 5 concentric 

 rows or cycles. Those in the interior, which are usually 6 in number, corresponding to the 

 6 primary septa (see fig. 24) but which sometimes appear to be more (see fig. 26) some of 

 the tentacles answering to the secondary septa coming into the same ring — are the largest, 

 although not nearly so large as in the Ulocyathus, and attached at a distance from the centre 

 of about half the radius. In the following cycles they diminish rapidly in size; so that in 

 the outer ring they appear only as small tubercles. In shape they are usually cylindro- 

 conical, somewhat constricted at the base with obtusely rounded point, and everywhere covered 

 with rather large roundish prominent nodules (see fig. 28) in which are accumulated a great 

 many small urticary cells. 



The color of the animal is, as in the Ulocyathus, a beautiful vermillion, which color is 

 more intense in the tentacles and particularly in the bucal folds. The coral itself, or the 

 polyparium, is on the contrary snow-white. 



Of this interesting Turbinolide I have only foimd 4 specimens, all in the same locality, 

 namely at the fishing station Skraaven in Lofoten at ,the depth of .300 fathoms on soft clay 

 bottom, together with Ulocyathus arcticus, which occurs here in quite enormous quantities 

 and of more considerable size than I have found it in any other place, namely with a trans- 

 verse diameter of 35 Mm. or I'/j". 



This new Genus may be characterised in the following manner.
