is comparatively unimportant, when those muscles in some other 

 Frogs to be shortly described are considered. As shown in text- 

 fig. 93 its branches to the transverse processes are limited to the 

 outer edges of these. The enormously expanded sacral vertebne 

 which overlie the ilia give off anteriorly the strongest slip of 

 muscle which I refer to the Ilio-lumharis * complex. A slender 

 slip of muscle represents the origin of the muscle from the ilium. 

 This arises from the tip of the ilium as it has been desci-ibed to 

 arise in Rana esculenta ; but instead of running forward as in

that frog, it runs dorsall}" at right angles to the longitudinal axis 

 of the body owing to the overlap of the sacral vertebra to which 

 it is partly attached. Megcdojyhrys differs, as will be seen presently, 

 from a number of other Frogs in the presence of a long, almost 

 strap-shaped and strong muscle which may perhaps be referred to 

 the Ilio-lumbaris complex. This arises from the ilium a long way 

 back and is continued straight forwards, without any inseitions 

 of detached slips on the way, to the third vertebra, to the outtr
