I found my colonies of this species on the tail of a sea snake (Enhydris hardwickii) 
and on the carapace of Limuhts moluccanus, taken in both cases in fishing-nets off 
Singgora near the mouth of the Tale Sap in January, 1916. 
The water had at the time a specific gravity (corrected) of 
I 0085. In both cases the colonies accompanied and partly 
grew over those of the Cheilostome Membranipora hippopus. 
My specimens agree closely in most respects with Duerden 's 
description and figures of Irish examples. The rhizome (pi. i, 
fig. 3) is in an intermediate condition, forming neither a simple 
branching structure nor a flat plate but having a modified 
cruciform arrangement. Pairs of opposed lateral branches are 
given off at irregular intervals and at the meeting place of the 
four arms thus formed small polygonal flattened plates are 
budded off from the lateral branches and the main stem in the 
same plane. It is from these plates that the upright stalks of 
the zooecia arise. This formation is not mentioned by Duerden, 
but is shown in his plate (fig. 5). The only point in which I 
find any actual discrepancy is in the form of the base of the 
zooecium and in the manner of its attachment to the stalk (see text-figure 3), but 
the stalk is so delicate that it is liable to be distorted ; in many of my specimens it 
has much the same appearance as in Duerden's fig. 3. My figure was drawn from a 
particularl}' well-preserved zooecium. 
So far as I am aware, T. pedicellata has not hitherto been recorded from tropical 
waters, but only from the North Sea and the west of Ireland, where it occurs on shells 
in moderately deep water. As it was found in the Tale Sap attached to marine ani- 
mals possessing considerable power of progression, we may suppose that it is not a 
permanent inhabitant of the lake, but enters brackish water occasionally.
