C. Urvillet appears to be confined in Australia to tropical waters. 
It is known from Cape York and Trinity Bay, and all the specimens 
recently forwarded are from Dunk Island. 
Digenia simplex, Ay. 
A southern extension can be recorded for this species, a speci- 
men frit Dunk Island collected by E. J. Banfield being received. 
In the southern hemisphere the plant appears to be more limited 
in its range than in the northern, as in the latter it spreads well up 
into temperate ede being frequent i in the Mediterranean and also 
on the coasts of

Evidently a rare species. Collected at Cape York many years 
ago by Daemel, and admirably figured and described by Sonder, 
the plant does not appear to have since been recorded. A goo 
supply of material was forwarded from Dunk Island, and this. for 
the most part, like the original gathering, was entirely sterile. A 
few pieces however bore cystocarps. These are of large size, and 
are produced on the marginal teeth of the pinnae. 
Vidalia fimbriata, J. sedate

The single gathering reasrved mepe cystocarps which were 
hitherto unknown. ey are borne on the adventitious shoots 
which spring from the surface of the _ Sree, and are produced, 
like the stichidia, on both sides of the thallus. Whether the 
rocarps are situated on the primary adventitious branch, or on the 
secondary “fruiting branchlets” whieh Falkenberg describes for 
the tetrasporangia, could not be ascertained. 
The plant is haga from various localities in the Indian Ocean 
and was collected by Harvey in West Australia, and during the 
“ Challenger ” Tixpedition at Cape York, but has not hitherto been 
met with elsewhere in the Australian Continent.
