4, and in the space from the last vessel to the endostyle 4—5 
are found. Quite close to the endostyle no stigmata are developed. 
The in testi ne lies on the left side of the branchial sac. The 
stomach, which is conical, is the thickest at the cardia. Ca. 10 
longitudinal folds are developed. A short, rudimentary coecum is 
present. Anus has two lips and is placed at a level of Vs of the 
length of the ascidiozooid. Gonads are not seen, but some young 
buds are present. 
This species must be placed in the genus Botryllus (s. lat.). Its 
nearest relations must be expected among the species of the former 
genus Sarcobotrylloides (or perhaps Botrylloides). It has, however, 
proved impossible to maintain these genera. The present species 
does not fully agree with any of the described species. Further 
investigation of this group, especially of different stages of devel- 
opment, will doubtless prove a very great part of the species to be 
identical, as pointed out by several authors. Therefore I shall, for 
the present, only call this form Botryllus sp.

Locality: Carnley Harbour, Amokura Harbour. At low tide, 
upon or between stones. 
Several specimens of different sizes. The largest specimen mea- 
sures 46 mm, which is not mueh in comparison with the largest 
samples of Hartmeyer and Sluiter. Some of the animals are 
attached to stones or shells with the larger part of the right side, 
in which case the siphons are turned to the left. The younger spec¬ 
imens have a smooth test, but in the older ones it is often more 
or less overgrown with Bryozoa, Hydroids and Didemnids. One 
specimen was covered nearly all over with the last mentioned or- 
ganisms, only the siphons were free. In this sample, which was 
attached with the entire right side of the body, the siphons were 
remarkably long, and their direction vertically to the long axis of
