constructed hinge and " testaceous heart-shaped ossicle," to show 

 that it belonged to this species. 



Bean-shaped Thracia, Thracia phaseolina, (T. pubescens, Mac, 

 Amphidesma declivis, Flem.) Not common. Occasionally met 

 with on sandy shores, as at Lossiemouth, January, 1853, and in the 

 boats just returned from sea. Mr. Murray has obtained some very 

 fine specimens from the Burghead boats. Banffshire coast, Edwards' 

 collection. 



Macgillivray's Thracia, Thracia villosiuscula. Apparently rare. 

 A single specimen, now in the Elgin Museum, was found by Mr. 

 Murray at Burghead; one from Buckie, Mr. McDonald; and one 

 from Lossiemouth, Mr. C. H. Grant. A single valve has been taken 

 from the stomach of a codfish. The following quotation, from the 

 c History of British Mollusca,' encourages the hope that Thracia dis- 

 torta will yet be detected in the Moray Firth. " The Rev. G. Laing 

 communicates it (T. distorta) from the Orkneys, and we have found it 

 in the Firth of Forth, (E. F.)" vol. i. p. 234. 



Delicate Cochlodesma, Cochlodesma prcetenue, (Amphidesma p.> 

 Flem., Anatina p., Mac.) " The Moray Firth (McAndrew)," F. $ H. 

 Burghead, Mr. Murray. Buckie, Mr. Macdonald. Occasionally to 

 be picked up in the Lossiemouth boats. On this species Mr. Mac- 

 donald gives the following remarks: — "Though a scarce British 

 shell, Cochlodesma prsetenue is by no means uncommon in the 

 Moray Firth. It may be procured either by the dredge or from the 

 fishermen's lines ; and examples often occur an inch and a quarter in 

 length by seven-tenths in breadth. The late Professor Macgillivray 

 states (Moll. Aberd. p. 295) that it is frequently brought up by the 

 fishing lines from deep water off Aberdeen, and gives its size as 

 nearly an inch and a half long, by an inch broad ; ' dimensions,' as 

 we are informed by the authors of the c British Mollusca,' ' far above 

 the average of English examples.' It would thus seem from its 

 extreme scarcity in all its recorded localities, and its comparative 

 abundance as well as its superior size on our own and on the Aber- 

 deenshire shores, that the north-east coast of Scotland is the head 

 quarters of this interesting bivalve." 



Razor-case Solen, Solen siliqua. (t Spout-fish." 



Sabre-case Solen, Solen ensis. 



Pellucid Solen, Solen pellucidus. " Moray Firth, in from thirteen 

 to thirty-four fathoms (McAndrew)," F. fy H. While fine specimens 

 of the first of these three razor or spout-fishes may be picked up at 

 all parts of the coast, even on the rough and high shingly beaches, a
