the body. Some of the specimens at my disposal are connected 
laterally with their tests so as to form a large flattened mass. 
Their tests are fragile and easily torn. The internal features are 
essentially in accordance with the earlier descriptions. The intestinal 
loop is as figured by Traustedt (1881, pi. IV). Its upper edge is 
at a level with the atrial siphon and the stomach is almost vertical. 
I may call attention to the faet that the siphons have a var- 
ying number of lobes. Typical for the genus is, branchial 
aperture: 8, atrial aperture: 6, but in some cases I found 5 5 
or 6 — 6. The same was the case with the ocelli. 
This circumnotial species has previously been recorded from 
the Auckland Isl. by the Nat. Antarctic Exped. (Herd man). 
It is evident that the Tunicate-Fauna of these islands has mueh 
in common with that of the Magelhaen-strait, SouthGeorgia 
and Cape. The described species of Alloeocarpa and 'Cnemidocarpa 
have their nearest relations here and Polyzod reticulata is known 
from the Magelhaen-strait. It is a very noticeable faet that only 
one of the species is known from New*Zealand, the widely destri- 
buted Coiella eumyota. It is also of interest to notice that Molgula 
amokurae has its nearest relation — M. tumulus — in Australian 
waters (Port Jackson). Otherwise there seems to me no reason to 
enter on a detailed discussion of the zoogeographical problems 
connected with the Tunicates of these regions, especially so long 
as the collection of the Tunicates from New Zealand seas has not 
yet been worked out.
