and the distance between two pairs is 0.8 mm., while the distance between the lateral pairs 
of two neighbouring polyps is somewhat greater (0.8—-1.1 mm.) so that in most cases it is 
very conspicuous which pairs appertain to the same polyp (fig. 1 d). The tentacles are short 
and thick or very broad and flat; their length is at the utmost 0.55 mm.; often they are 
shorter and knobbier. The oral cone is proximally and distally higher than in the middle 
(fig. 1 6 )\ the transversal axis is 0,875 mm., the sagittal axis is 0.2 mm.. The mouth itself is 
also very much transversally elongated (fig. 1 c and d) and the proximal and distal ends are 
wider, whilst in the middle the walls of the mouth are pressed together. On the stem and the 
older parts of the branches the polyps have quite the same structure; the tentacles of the 
sagittal pairs are separated by a somewhat greater distance than the tentacles of the lateral 
pairs, but this is also in a minor degree visible on the younger branches. Nowhere young 
polyps are found between the adult polyps. 
This specimen is closely related to Clad'opathes Br. and Taxipathes Br. However there 
are too many differences in the mode of branching of the colony, the mouth, the structure of 
the polyps and especially in anatomical structure to join this specimen to Cladopathes Br. The 
mode of branching becomes more like that of Taxipathes , while the to a high degree trans¬ 
versally elongated mouth is also to be found in Taxipathes. The mode of branching is on 
some points also like Parantipathes Br., but the structure of the polyps is wholly different. 
On ground of the many and important deviations this new genus is formed.

The base of this specimen is free and hooked after the model drawn by Brook on his 
PI. IX, fig. 5. The first 7 cm. of the stem are unbranched; the branched part is 25 cm. long. 
The base is hooked in the same plane as that of the branches; the rest of the unbranched 
part is straight or slightly curved forwards. At the beginning of the branched part there is a 
slight curve to the front, followed by a straight part, which in its turn is followed by a slight 
curve to the front; the top part of the colony is slightly curved backwards. The proportions 
of the diameter of the hook are the same as in Brook’s figure. The greatest diameter of the 
broad flat side is 1.3 mm., about the place where the straight part of the basis begins. Farther on 
the diameter lessens gradually towards the top which ends fully 2 cm. above the last branch. 
The branches alternate regularly right and left; only in one single case a branch on the right
