50 THE INVERTEBRATE FAUNA 
Mr Robert Gray found it not uncommon 
at Dunbar. 
III. BRAcHYURA— 
LEPTOPODIADA. 
Stenorhynchus rostratus (Linn.). 
Prestonpans (Hd. Mus.); Firth of Forth 
on mud and sand, generally distributed 
(Howd.). 
This species, the S. phalangium of authors, 
is not uncommon. We have dredged it 
on the oyster bank at 5 fathoms, in Aber- 
lady Bay, near Elie, and elsewhere. 
MAIADA. 
Inachus dorsettensis (Penn.). 
Deep-sea lines (Howd.). 
Hyas araneus (Linn.). 
Very abundant. We have often taken it 
between tide marks at Newhaven, Aber- 
dour, and other places, and have dredged 
it off Longniddry in 14 fathoms, and in 
Aberlady Bay and on the oyster bank in 
5 fathoms. It occurs in almost every 
dredgeful in the lower reaches of the 
Firth. 
H. coarctatus (Leach). 
Largo Bay, Inchkeith, ete. (/‘B.) ; Firth 
of Forth (Leach, in Brit. Mus.). 
This species was first discovered in the 
Firth of Forth by Dr Leach. It is fairly 
common but less plentiful than 7. araneus. 
We have obtained it south-west of Inch- 
keith, 5 fathoms, in Aberlady Bay, 5 
fathoms, and in many other localities. 
PARTHENOPODA. 
Eurynome aspera (Penn.). 
Prestonpans and Portseaton (Howd.).
