liarity, and it must be remembered that H artmeyer (1912) says 
about C. asymmetra : „Bei dem Typus stossen die beiden Gonaden 
mit ihren ventralen Randern sogar vollståndig zusammen". 
The i ntesti ne forms a weak, s-shaped loop. The stomach 
has internal folds which are seen through the wall. No coecum is 
present. Anus has a plain border without lobes or incisions. 
Endocarps are found on the left side. Two in the intestinal 
loop, one between oesophagus and rectum, two above and a few 
beneath the intestine. 
It is evident that this species must be placed in the group 
which Prof. Hartmeyer calls „h u m i 1 i s-Gr u p p e“. To this group 
C. humilis (Heller), C. cerea (Sluit.), C. gregaria (Kestev.), C. asym¬ 
metra (Hartm.) and C. robinsoni Hartm. belong. Prof. Hartmeyer 
considers it a very natural group which, for the present, he has placed 
in the genus Cnemidocarpa Huntsm. The three first mentioned spec¬ 
ies are from Australia-N. Zealand, but I do not find them very nearly 
related to my species. C. humilis is imperfectly described and C. cerea 
has differently shaped gonads; the same appears to be the case in 
C. gregaria. With C. asymmetra and C. robinsoni (South Africa and 
Juan Fernandez) it is a different thing. The present species is very 
closely related to them, if not identical with one of them. The 
differences in the development of dorsal tubercle, gonads and 
branchial sac are evidently not important characters, as those or¬ 
gans are very variable (Michaelsen 1915, p. 395). I am not 
sure, whether C. aucklandica is most nearly related to C. asymmetra 
or to C. robinsoni , therefore I think it will be right to describe it 
as new, until further material can be produced.

to shells together with Alloeocarpa. The surface of the colonies is
