102 ANNALS OF SCOTTISH NATURAL HISTORY 



dead, it has not the appearance of being a fossil form. On 

 submitting it to Mr. J. T. Marshall of Torquay, he was inclined 

 to think it was a distorted form. Although I think it is quite 

 as much entitled to rank as a variety as many other British 

 " forms " until it can be examined alive and in sit it, it will be 

 quite enough to note its occurrence. 



DONAX VITTATUS (Da C.), var. ALBIDA, Marsh, (described by 

 Mr. Marshall in "Journal of Conchology " for October 1893). 

 On submitting some Donaces to Mr. Marshall, he informed me 

 that they were of this variety. It appears to be very abundant 

 off Aberdeen, and could have been picked up in hundreds after 

 the great gale in January 1895. 



MACTRA STULTORUM, Z., var CINEREA, Mont. Quite as common as 

 the type on Aberdeen beach after heavy gales. 



SCROBICULARIA ALBA (Wood). A distorted form is often cast upon 

 the beach at Aberdeen. 



SOLEN SILIQUA, Z., var. ARCUATA, Jeff. On rare occasions on 

 Aberdeen beach. 



SAXICAVA NORVEGICA (Spengl.). A single valve in the late T. 

 Edward's collection of Moray Firth shells. Mr. Dow found 

 on board a trawler at Aberdeen, which he says was fishing off 

 Peterhead, a dead specimen in September 1893. 



SAXICAVA RUGOSA (Z.), var. MINUTA (Z.). On Corallines from deep 

 water off Aberdeen. Var. PR^ECISA (Mont.}. Common on 

 Laminaria roots along the whole coast. 



TEREDO NORVEGICA, Spengl., var. DIVARICATA, Desk. A mass of 

 tubes, 26 inches long, of this variety was brought into Peter- 

 head in 1893 by a long-line fisherman, who found it attached 

 to his lines in the Moray Firth. It is now in the Peterhead 

 Museum. 



PATELLA VULGATA, Z., var. PICTA, Jeff., and var. DEPRESSA, 

 Penn. Both forms are common on rocks south of Aberdeen. 



HELCION PELLUCIDUM (L.), var. ELONGATA, Jeff. Dead specimens 

 frequent on the beach. 



TECTURA TESTUDINALIS (MiilL], var. PALLIDA, Verk. In the rock 

 pools at Girdleness. 



TECTURA VIRGINEA (Milll.\ var. LACTEA, Jeff. Rock pools on the 

 Kincardineshire coast. 



TROCHUS MILLEGRANUS, Phil., var. PYRAMIDATA, Jeff. Dead 

 specimens of this variety are often brought in from deep 

 water by trawl-boats.
