168 Part L11.—Fifteenth Annual Report 
in the deep water between Arran and the Heads of Ayr, and another 
midway between the Island of Sanda and Beunan Head. 
Triglops Murrayt, Giinther.—A young specimen of this somewhat rare 
species was taken in the shrimp-trawl, a short distance to the eastward 
of Sanda. 
The ‘Black mouthed dog-fish’ (Pristiwrus melanostomus) and the 
‘Lesser spotted dog-fish’ (Sylliwm canicula) were captured in the ‘ Gar- 
laud’ trawl; the former was taken off Arran, and the latter in the vicinity 
of Ailsa Craig. 
A few specimens of the ‘Flapper skate’ (Raia macrorhynchus) were 
obtained by the ‘Garland’ in different parts of the seaward area of the 
Clyde; a specimen, captured in the deep water to the east of Arran, 
measured 40 inches across the pectoral fins, 
MOLLUSGA. 
Trochus granulatus, Born.—A single living specimen of this molluse 
was taken off the Island of Sanda. This locality, though near the mouth of 
the estuary, is still within the Clyde area ; and as this species does not ap- 
pear to have been hitherto included among the recent mollusca of the 
Clyde, its occurrence here is of interest. Dr Jeffreys, in British Conchology, 
states that the species has been obtained off the Mull of Galloway m 
50 fathoms, and also refers to it having been found in Belfast Bay ; 
but adds that the two broken specimens found there had probably been 
accidentally introduced. These are the nearest to the Clyde, of the 
localities from which the species has been recorded. 
CRUSTACEA. 
Gonoplax angulata (Fabricius).—A male specimen of this crab was 
captured on the 3rd of November 1896, in the vicinity of Ailsa Craig, 
and on the following day a female was obtained a few miles south- 
eastward of the Mull of Cantyre. This species has for many years 
past been included among the Clyde crustacea ; but in recent years there 
seems to be a tendency to doubt the accuracy of the Clyde records. 
The capture of these two specimens, even though the localities be near 
the seaward boundary of the estuary, will therefore help to some extent 
to remove the uncertainty as to the correctness of these earlier records. 
Nika edulis and Pasaphea sivado, etc.—Both of these crustaceans are 
sometimes of more or less frequent occurrence near the mouth of the 
Clyde estuary. 
Hippolyte prideauxiana, Leach.—A single specimen of this little shrimp 
(a female with ova) was obtained near the outer boundary of the Clyde 
in November last ; it is an addition to the Clydefauna. H. prideauxiana 
is sometimes captured off the coast of Devon. J am indebted to the Rev. 
T. R. R. Stebbing for the name of the species. 
Striella norvegica, G. O. Sars.—One or two specimens were recently 
identified among some surface tow-net material from the Clyde, collected 
a few miles to the east of the Island of Pladda. This is also an addition 
to the Clyde fauna.
