4430 Mollusks. 



Bullina truncata and B. pellucida, Macq.) Frequent in shell-sand. 

 Common, alive, between tide-marks at Burghead, Mr. Macdonald. 



Oblong Cylichna, Cylichna umbilicata, {Bulla umbilicata, Flem. ; 

 Bullina umbilicata, Mac.) In shell-sand, but more rarely than the 

 preceding species. 



Transparent Amphisphyra, Amphisphyra hyalina, [Bulla minuta, 

 Mac.) First discovered in the Moray Firth by Mr. Murray at Burg- 

 head, where it occurs occasionally in shell-sand. 



Banded Tornatella, Tornatella fasciata, (T. tornalis, Flem., and T. 

 tornalis, T. pellucida and T. pusilla, Mac.) Occasionally to be 

 picked up on the shore. It is preyed on by the haddock. 



Bulla-like Akera, Akera bullata, [Bulla Akera, Flem.) "The Rev. 

 Charles Cordiner, of Banff, observed this shell in the Moray Firth, 

 and transmitted specimens to the Duchess of Portland," Fleming, 

 British Animals, p. 292. 



Cranch's Bulla, Bulla Cranchii. Frequently to be seen in the sto- 

 mach of the haddock. Mr. Murray finds it at Burghead. 



Wood-tinted Scaphander, Scaphander lignarius, [Bulla lignarius, 

 Flem.) Not unfrequently found as part of the food of the haddock ; 

 the specimens seem smaller than those found on the West coast 

 of Scotland. 



Rough Philine, Philine scabra, [Bullcea catenulifera, Mac.) Occa- 

 sionally found in shell-sand, but more frequently as part of the food 

 of the haddock. 



Punctated Philine, Philine punctata, (Bullcea punctata, Mac. 

 One specimen, alive, has just been found (July, 1854) by Mr. Murray 

 at Burghead, near low-water mark. " Off Trouphead, Aberdeenshire, 

 in sixty fathoms [Thomas),'''' F. # H. These two facts show the great 

 range as to the depth in which this rare species may be found. Both 

 Philine quadrata and P. pruinosa have been met with on the North of 

 the Moray Firth, at " Zetland," and also on the South— the former 

 on the " Northumberland coast," and the latter in the " Firth of 

 Forth." 



The Sea-Hare, Aplysia hybrida, [A. dipilans and A. punctata, 

 Flem.) Frequently to be met with. On one occasion Mr. Martin 

 observed immense numbers drifted on the shore, along with sea-weed, 

 to the west of Burghead. " Very abundant on the rocks at Burghead, 

 in July, 1852," Mr. Macdonald. 



In the Appendix II. to the ' History of British Mollusca,' p. 290, it 

 is stated that Diphyllidia lineata has been found " off the Shetland 

 Islands," and " from the boats at Whitburn, in the county of Durham."
