The Table facing this page will, we hope, be useful to future 

 investigators. It shows at a glance the arrangement of 31 of the 

 most interesting muscles in the bodies of Ungulates. So far as we 

 know, the muscles which are not included have either the gene- 

 ralised mammalian arrangement, or else are specially character- 

 istic of all Ungulates, in which case they have already been given 

 on p. 291. Another point in which this Table may be valuable is 

 that it draws special attention to the gaps in our knowledge, and 

 this is often the first step towards filling them up.
