lost, he is unable to give any further information respecting its 

 locality. 



*Solen siliqua is found at Lamlash, and is cast up frequently after 

 storms in Karnes Bay, C umbrae. The specimens from this last 

 locality are remarkably fine ; an example in my cabinet measures 

 eight and a half inches long and one and a half wide, dimensions 

 considerably exceeding those given by Forbes and Hanley, and 

 to which it is said by them rarely to attain. 



* „ ensis. Common in suitable localities, and attains a very 

 large size : those in my cabinet from Fintry Bay, Isle of C umbrae, 

 where it is found cast up in abundance after storms, measure six and 

 a half to seven inches in length, and an inch in width, nearly double 

 the size of ordinary specimens. " Spout-fish " is the name by which 

 the Solens are known in this part of Scotland. 



„ pellucidens {Solen pygm&us). Ayr, Bute, Smith. I have 

 taken it in deep water just outside Lamlash Bay, off Clachland Point, 

 and to the west of C umbrae, between Fintry and Shell Bay, but it is 



scarce. 



Fam. VIII. Solecurtidce. 



Solecurtus coarctatus {Solen anliquatus). I have not met with 

 this species ; but it is undoubtedly a native of the Clyde, as it occurs 

 in the lists of both Mr. Smith and Dr. Landsborough. 



Fam. IX. Tellinidw. 



Psammobia vespertina. The Setting Sun is very abundant in Loch 

 Ryan to the south of the district to which this catalogue refers. In 

 the district itself I have not found it, nor is it mentioned among the 

 Clyde shells by Mr. Smith, or those of Lamlash Bay by Dr. Lands- 

 borough. It appears, however, to occur at Loch Ranza, which is at 

 the northern extremity of Arran, as there are two specimens in 

 the British Museum labelled as from that locality, and presented by 

 the Rev. D. Landsborough. 



„ Ferroensis. Ayr, Bute, Smith. I have taken it in 



Kames Bay, C umbrae, and at Lamlash, but only procured a specimen 

 or two from each locality. 



„ tellinella {Psammobia florida). Occurs occasionally 



in the Coralline Zone on the west of Cumbrae and in Lamlash Bay. 

 Its colours in this part of Great Britain have not the brilliancy which 

 makes this such a lovely shell when taken further south : at Herm I 

 have met with snow-white specimens, and one of an uniform dark 

 purple.
