OF KEMAINS OF THE GREAT AUK.

upper and lower portions of humeri, lower ends of tibifp, and 

 entire femora, &c. 



We have therefore doubtless the bones of a large number of 

 Garefowl and aquatic birds. 



The following is a list of the other animal-remains from the 

 mound : — 



Mammals. 



Cervus elaphus, L. Red Deer. Many 

 of the bones have been rubbed. 



Maries foina, L. Marten. 



Lutra vulgaris, Erxl. Otter. 



Ovis aries, L. Sheep. We have 

 only one portion of a bone that 

 we are certain belong.s to this 

 animal ; and it was found near 

 the upper surface of the deposits, 

 and is in better preservation than 



the other remains, which may in- 

 dicate it is more recent. 



Mus decumanus, Pall., or rattus, L. 

 Eat. 



Lepus cuniculus, L. Rabbit. Found 

 in old burrows ; and the remains 

 appear to be recent. 



Phoca vitidina, L. Common Seal. 



Sus scrofa. Pig. 



BlEDS. 

 TJria troile, L., orgrylle, L. Guillemot. And several other shore-frequenting 

 birds, of which furculge, coracoids, scapulee, humeri, and femora remain for the 

 present undetermined. 



Fish.

Labrus maculosus, El. Wrasse. 

 Mugil septentrionalis, Giinth. Grey 

 Mullet. 



Acanthias vulgaris, Risso.

 Latvicardium norvegicum, Spengl. 



With regard to these remains, we may observe that the bones 

 of the Eed Deer, though found all through the strata, even in 

 the highest, were most plentiful in the lower deposits, and seemed 

 to become much less common in the upper layers. It would seem 

 that this probably indicates that the animal was becoming gra- 

 dually less abundant during the period that Caisteal-nan-Gillean 

 was inhabited. We may also remark that, as in our excavations at 

 the Crystal-Spring Cavern, Colonsay, we only found the bones 

 of the Red Deer in the lowest deposits of the cave-floor, it 

 appears therefore that there is good reason to suppose that the
