pi. lxxxvii. fig. 1-7. 



Habitat. — Off St Monans, Firth of Forth. One specimen only of this 

 fine and distinct species was obtained. It occurred among material dredged 

 in about 14 fathoms water ; bottom, clean sand. 



Gyclopicera gracilicauda, Brady.

 lxxxiii. figs. 1-10. 



Habitat. — Off St Monans, Firth of Forth. Several specimens were 

 obtained among dredged material. This was readily recognised by the 

 slender abdomen and long caudal stylets. It appears to be a somewhat 

 rare species.

fio- 1. 



Habitat. — On the gills of a ' John Dory ' (Zeus faber), caught in the 

 vicinity of Largo Bay, Firth of Forth. Baird (Joe. cit.) gives a very 

 characteristic figure of this Chondracanthus. The arrangement of the 

 numerous "elongate appendages (they can scarcely be called spines as 

 Baird describes them) which surround the parasite is such as to impart to 

 it a somewhat handsome appearance. There does not appear to be any 

 previous record of this species from the Firth of Forth. 



Ghrondracanthus merluccii, Holten. 



From the skin of the branchial cavity of a Hake. Merlucius vulgaris, 

 landed at Newhaven, February 1885. 



AMPHIPODA.

 1870. Cressa schiodtei, Boeck, ' Crust. Amph. bor et Arct.' 



Habitat. — From a large ' root ' of Laminaria brought up in the trawl- 

 net at Station V., Firth of Forth, in February 1892. Several specimens 

 were obtained. From what I can learn regarding this species it appears 

 to be somewhat rare in the British seas. It was first obtained by Spence 

 Bate among trawl refuse 'from near the Eddystone Lighthouse.' David 

 Robertson records having taken it ' off stones and nest of Lima hians
