Part III. — Eighth Annual Report 
Diastylus rugowL, G. O. Sars, Middelhavets Cumaceer, p. 98, 
tab. 34-38 (1879). 
Habitat. — Largo Bay and other parts of the Forth. This seems to be 
a well-marked species, though it has not previously been recorded for the 
Estuary. 
Campylaspis affinis, G. O. Sars, $ . 
Campylaspis affinis, G. O. Sars, Nye Dybrands Crustaceer fra 
Lofoten, p. 160 (1870); Extract, p. 16. 
Habitat. — Vicinity of the Bass Hock, rare. The cephalic shield is 
thickly sprinkled with purple spots, whicli impart to it a somewhat uni- 
form purplish colour. The Rev. T. R. R. Stebbing, to whom I submitted 
the specimen, points out that it comes very close to C. rubrii-tiitda 
(Liljeborg) in the form of the tail appendages; it differs in the coloration.

Erythrops serrata, G. O. Sars, Mon. over de ved Norges Kyster 
Forkommende Mysider., Frste Hefte, p. 27, tab. ii. figs. 1-2 
(1870). 
Habitat. — South-east of the Bass Rock 4 or 5 miles, rather rare. In 
this species the outside edges of the antennal scales are deeply toothed, 
with the teeth pointing forwards, and thus differs from the other two 
species of Erythrops recorded for Britain. There appears to have been 
some confusion in previous records of the distribution of Nyctiphanes 
norregica and Boreophausia raschii, the first being understood to be a more 
common species. I find, on the coutraiy, that the latter is comparatively 
abundant, especially in the outward part of the Estuary, while the other is 
rather rare. 
MOLLUSCA. 
Miss J. E. Carphin kindly placed her extensive collections of Forth 
Mollusca at my service, which has enabled me to include a few interesting 
additions to the local list of species belonging to this group. 
LAMELLIBRANCHIATA. 
LuCINIDiE. 
Diplodorda rotundata (Montagu). 
telene rotundata, Mont., Test. Brit., p. 74, t. ii. fig. 3. 
Diplodonta rotundata, Jeffreys, Brit. Conch., vol. ii. p. 254; vol. 
v. pi. xxxiii. fig. 4. 
One living specimen of this pretty bivalve was found at Newhaven Pier 
by Miss -I. E. Carphin. It had been brought in from the outer part of 
the Estuary on the fishermen's lines. 
CARDIIDiE. 
Cardium nodosum, Turton. 
Cardium nodosum, Turt., Conch. Dith., p. 186, t. xiii. fig. 8. 
Cardium nodosum, Jeffreys, Brit. Conch., vol. ii. p. 283 ; vol. v.
