4428 Mollmks. 



Northern Trichotropis, Trichotropis borealis, (Fusus Laskeyi and 

 Trichotropis umbilicatus, Mac.) Has been found in two instances on 

 the southern shore of the Firth ; at Burghead by Mr. Murray, and at 

 Buckie by Mr. Macdonald. 



Hedgehog Rockshell, Murex erinaceus, (Triton erinaceus, Flem.) 

 Only one, and that a mutilated specimen, has been found by Mr. 

 Martin at Lossiemouth, probably brought thither by tidal currents, or 

 in ballast, from some distant locality. 



White Whelk or " Horse Buckie," Purpura lapillus. Most abun- 

 dant around the whole coast; particularly, and in many of "the 

 guises it presents," at the " back shore " of Burghead. 



Net-worked Nassa, Nassa reticulata. Only two specimens of this, 

 elsewhere a rather common shell, have been as yet collected in 

 the Moray Firth ; one by Mr. Duff, now in the Elgin Museum, and 

 the other by Mr. Martin. To the denizenship of this species the 

 same doubt must be attached as noticed in reference to Murex 

 erinaceus. 



Black-spot Nassa, Nassa incrassata. Abundant among shell-sand ; 

 and often to be met alive adhering to sea-weed, &c. Mr. Macdonald 

 has found it in the stomach of Solaster papposa. 



Waved Buccine, Buccinum undatum, (also B. carinatum, Flem. 

 and B. Anglicanum, Flem. and Mac.) Abundantly cast up on the 

 beach ; and frequently taken up by the fishing lines, whether in- 

 habited by its original occupant or by the hermit crab. Mr. Murray 

 mentions that in both these states it is found among the rocks 

 at Burghead. This and the larger species of Fusus get the provincial 

 name of " roaring buckies." 



Islandic Spindle-Shell, Fusus Islandicus, (F. comeus, Flem. and 

 Mac.) Frequent. 



Symmetrical Spindle-Shell, Fusus propinquus. A few very young 

 specimens were taken from fish killed in the Moray Firth ; but 

 a full-sized and complete one, though long looked for along the coast, 

 was not met with until the 26th of October, 1853, when it was by the 

 merest chance seen among a parcel of shells scattered about as nur- 

 sery playthings, but which had been gathered by children and 

 brought by them from their sea-bathing quarters at Lossiemouth the 

 previous August. It is now in the Elgin Museum. 



Common White Spindle-Shell, Fusus antiquus. Very common. 



Banff Trophon, Trophon clathralus, (Fusus Bamjius, Flem., Pleu- 

 rotoma Banffium, Mac.) Three specimens have been obtained by 

 Mr. Murray, at Burghead ; it has also, but rarely, been seen among 

 shell-sand.
