This paper has been carried out on the same hues as those on 

 the Rodentia, Carnivora, and Edentata which have preceded it \ 

 We have as far as possible carefully compared and incorporated 

 the existing literature, and have checked and supplemented it by 

 a series of dissections of our own. In deference to the suggestion 

 of sevei'al critics ^^"hose opinion we valne, we have paid special 

 attention to the nerve-supply of the muscles, though here the 

 literature helped us very little, and we ^\ ould ]ike to point out 

 tliat, while there is sufficient material to make us pretty sure of 

 eliminating the effects of variation on the attachments of muscles 

 in the Orders reviewed, any accurate records of dissections of 

 nerve-supplies, however incomplete, would be of great value to 

 future reviewers. 



As in former papers, small numerals refer to the list of animals 

 at the commencement of the paper, and Roman figures to the 

 bibliography at its end. Those animals in the list against which 

 jio author's name is placed have been dissected by ourselves. All 

 general observations on the Order we shall reserve until the trunk 

 and hind-limb have been described. In conclusion, we beg to thank 

 those gentlemen, especially Prof. Howes and Mr. Beddard, who 

 have so kindly helped us with material, and Prof. Macalister, 

 Prof. Paterson, Dr. Dun, and Dr. Thompson, who have placed 

 hitherto unpublished notes at our disposal.
