APPENDIX. 
Since the preceding pages have been printed we have re- 
ceived additional records of species from Mr Balfour, of 
Cambridge, and Professor Cunningham, of Belfast; these, along 
with others obtained by ourselves during a few days dredging 
in the neighbourhood of Inchcolm, and some previously 
omitted, are now inserted. 
ALCYONARIA. 
Virgularia mirabilis (Linn.). 
We found this abundant in 5 to 10 fathoms, 
between Aberdour and Inchcolm, on a bot- 
tom of stiff blue mud. 
OPHIURIDEA. 
Amphiura filiformis (Miill.). 
We have dredged this species on several 
occasions lately near Inchcolm, 18 fathoms. 
HOLOTHUROIDEA. 
Psolus phantapus (Linn.). 
Professor R. O. Cunningham informs us 
that he has frequently obtained this 
species, taken at the entrance to the Firth, 
from the Prestonpans fishermen. 
POLYZOA. 
Bugula purpurotincta (Norman). 
We have dredged this in considerable 
quantity on the west and north-west sides 
of Inchcolm, in 10 to 15 fathoms. 
CIRRIPEDIA. 
Balanus hameri (Ascanius). 
Professor Cunningham writes, “I once 
obtained a magnificent mass attached to a 
stick, which it covered for about 2 feet.” 
AMPHIPODA. 
Byblis gaimardi (Kroyer). 
St Abb’s Head, 40 fathoms (Jetz.).
