the same time, attached to Mytilus edulis and M. modiolus 
and to the test of Polycarpa pomaria, were of the depressed 
form. 
Polycarpa pomaria, Savigny. 
Only a single specimen of this species had been recorded 
before from the district. It has since been taken on three 
occasions. One large specimen was dredged off the north 
coast of Anglesey in the “‘ Hyena”’ cruise of 1886: a small 
specimen was collected at Hilbre Island on June 4th, 1887; 
and half a dozen large specimens and some small ones were 
obtained in the dredgings from the ‘“‘ Hyzena”’ between the 
Calf and Port Erin in May, 1888, depth twenty fathoms. 
These last are very much mis-shapen from containing 
large specimens of Modiolaria marmorata, but had no 
parasitic Amphipoda or Copepoda in their branchial sacs, 
with the exception of one specimen of probably a new 
species of Doropygus, a specimen of which was also 
obtained along with a Doropygus normani in the branchial 
sac of a Styela rustica dredged off Skate Island in Loch 
Fyne. 
Polycarpa rustica, Linn. 
A specimen of this species was collected at Puffin Island 
on July 24th, 1888. 
CYNTHINZ:. 
Cynthia echinata, Linn. 
A single small specimen of this beautiful species was 
dredged from the ‘‘ Hyena,” on May 20th, 1888, between 
the Calf and Port Erin, from a depth of twenty fathoms. 
It is new to the fauna, not having been taken in the 
L.M.B.C. district before, and it is our only representative 
of the sub-family Cynthine.
