Geodinella vestigifera Dendy.

2 miles East of North Cape. 55 fathoms, hard bottom, 2/1.1915. 
Outer appearance and skeletal arrangement agree very well 
with the type. The same spiculation is also found and of nearly 
the same dimensions; it is very curious that the styli are here 
likewise often abnormal; several of them bear the mark of being 
of tetraxonoid origin, which is proved by their having the axial 
canal split up into three branches at the base; other indications 
of the same faet are given by Dendy, and are also seen here. 
The choanosomal oxea are often centrotylote. The short curved 
oxea measure down to about 200 and transitory stages between 
these and the bigger ones are found. 
Hitherto known from Spirits Bay, near North Cape, N. Z, 
Monosyvinga nov. gen. 
Stellettidae with the body produced into a special 
cloacal tube, which has its own special skeleton built 
up of orthodiaenes. The microscleres are oxyasters, 
chiasters, and trichodragmata. 
This is an extremely interesting new genus; as will be seen 
from the description of the species it comes very near to Tribra- 
chium and Disyringa, mainly differing from these in having chiasters 
and no sanidasters. There are now two possibilities: 1. Monosyringa 
is a converging genus, which has developed the curious cloacal 
tube independently; this view is sustained by the faet, that the 
genus does not possess sanidasters, but chiasters. Or 2. Mono¬ 
syringa is really closely related to the two mentioned genera; this 
view is. sustained by the construction of the tube, which is nearly 
iJentical with that of the two others; but if there is a close rela- 
tionship, then the occurence of sanidasters is of no far-reaching 
taxonomic value. The question cannot be solved as yet. I should, 
however, think, that the former view is the right one; A cloacal
