List of Shells and Zoophytes from the Firth of Forth. 115 



With the exception of the white variety of Tellina crassa, 

 dredged to the south-west of Inchkeith, in five fathoms 

 water, all the above were brought in on the lines of the 

 Newhaven fishermen, probably from the mouth of the Firth, 

 and were collected by myself in 1 883-84. 



Jeffreys mentions that Scalaria trevelyana was found by 

 Gerard in the Firth of Forth. 



We are probably indebted to Captain Laskey for the dis- 

 covery of Trichotropis hoi^ealis. About the beginning of this 

 century he found at Dunbar a minute shell, which he figured 

 in the Memoirs of the Wernerian Society, vol. i., as the young 

 of Pennant's Murex carinatus. In 1841 Professor M'Gillivray 

 found the same shell at Aberdeen, and named it Fusus Laskeyi, 

 but he afterwards identified it as the young of Trichotropis. 



Mollusca previously recorded, but rare in the Firth : 



1. Nucula tenuis (Mont.). 



Newhaven. 



2. Area tetragona (Poll). 



Newhaven. Found by Mr J. Eobertson. 



3. Gyprina islandiea (Linn.). 



A curious distortion. Portseaton beach. 



4. Vemcs casina (Linn.). 



A distorted valve, l^ewhaven. 



5. Thracia convexa (W. Wood). 



A large perfect specimen. Newhaven. 

 Zoophytes not previously recorded from the Firth of 

 Forth : 



Hydroida — 



Sertularia fusca (Johnst.). 



Newhaven. From deep water. November 1883. 



POLYZOA — 



Bugula flahellata (J. V. Thompson). 



Newhaven. November 1883. 

 Cellepora dichotoma (Hincks). 



Newhaven. JSTot rare on zoophytes from deep 

 water, especially Hydrallmania falcata and 

 Antennularia ramosa. It has perhaps been pre- 

 viously confounded with Cellepora ramulosa.
