The spicules of the tentacles and other parts of the anthocodie in C. regin@ are spindle 
shaped and provided with shallow tubercles Fig. 8c and @. As none of the autozooids were 
expanded it is impossible to give any definite statement as to the arrangement of these spindle 
shaped spicules in the anthocodie. 
2. Corallium halmaheirense n. sp. (Figs 5, 6, 0). 
Stat. ı5o. 0°6'N., 129°7'.20. 1089 Metres. 2 Fragments. 
The remarks issued by Prof. WEBER concerning this station are as follows *Trawl torn 
to pieces; fore beam bent; obviously met with very rough bottom”. The two fragments of the 
species obtained may be either the terminal branches of colonies of considerable size broken 
off by the trawl as it bumped along over the rough ground or they may represent nearly the 
whole colonies of a diminutive species peculiar to this region. To this initial difficulty, namely 
our want of knowledge of the size of the colony, in determining the species, may be added 
the second, that the small size of the fragments affords very few opportunities of studying the 
variations in the common characters. It is therefore impossible to declare with confidence that 
this is a new species. If we had larger specimens the species might exhibit stronger affınities 
with the japanese species Corallium sulcatum or C. boshuensts than the fragments do, but on 
the other hand they might confirm the distinetion of the species. My own opinion is that it is 
a more convenient course to give for future reference a distinct geographical name to these 
specimens from the Djilolo passage at the same time admitting that the evidence that the 
species is really distinet is not convincing; rather than refer them with some hesitation to a 
known species. 
One specimen, which I will call specimen A is ı5 mm. in height and the diameter of 
the axis is 2,25 mm. It has four lateral branches from 5—S mm. in length with two small 
branches on one face which are about 3 mm. in length. These facts suggest that if this is a 
fragment of a large colony, the branching of such a colony would be mainly in one plane, a 
condition we might expect to meet in a coral from such a great depth. The other specimen (B) 
is 16 mm. in height, the main axis is half-moon shaped in section with a greatest diameter of 
3,75 mm. The longest branch is 13,75 mm. in length; but there are several other smaller 
branches arising from one face of the coral. This specimen is a great deal more worn than 
the other, the coenenchym being absent from a considerable portion of the branches. 
Judging from the evidence afforded by these two fragments it seems probable that the 
ramification of this species is mainly in one plane but the terminal branches exhibit secondary 
branchlets arising on one face of the coral only. 
The axis is very pale pink, almost white, in colour but in specimen A there is an excentric 
core of a darker pink colour. The coenenchym is of an orange-red colour and much darker 
than the axis. In both specimens there is a distortion of growth due to the presence of an 
epizoic polychaete worm. In specimen A, the worm remains in situ (Fig. 5). 
The verruc& of the autozooids are conical in shape very prominent and marked externally 
by eight deep longitudinal grooves. These verruc& are from 2—3 mm. in height. It cannot be
