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. 



ALCYONAEIA. 



Virgularia mirabilis (Linn.). 



We found this abundant in 5 to 10 fathoms, 

 between Aberdour and Inchcolm, on a bot- 

 tom of stiff blue mud. 



OPHIUEIDEA. 



Amphiura filiformis (Mii.ll.). 



We have dredged this species on several 

 occasions lately near Inchcolm, 18 fathoms. 



HOLOTHUKOIDEA. 



Psolus pliantapus (Linn.). 



Professor E. 0. 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. 



CIEEIPEDIA. 



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 (Krb'yer). 



St Abb's Head, 40 fathoms (Metz.).
