Part III. — Fifteenth Annual Report 



in the deep water between Arran and the Heads of Ayr, and another 

 midway between the Island of Sand a and Beunan Head. 



Triylops Murrayi, 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 ' (Pridiurus melanostomus) and the 

 ' Lesser spotted dog-fish ' (Syllium canicula) were captured in the ' Gar- 

 laud ' trawl ; the former w r as taken off Arran, and the latter in the vicinity 

 of Ailsa Craig. 



A few specimens of the 'Flapper skate' (Rata macrorhyjichut;) 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. 



Mollusca. 



Trochus gramdatus, Born. — A single living specimen of this mollusc 

 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 in 

 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 Pasaphcea 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 Clyde fauna. H. prideauxiana 

 is sometimes captured off the coast of Devon. I am indebted to the Rev. 

 T. R. R. Stebbing for the name of the species. 



Siriella norveyica, 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.
