ON THE GENERAL MORPHOLOGY OF THE MYXINOID FISHES. 747 



33. Geography of the Preceding Muscles. 



I include here two tables indicating the longitudinal extent of the muscles in my 

 large series of sections on both sides of the body. These tables will be useful in 

 subsequent sections of the work, especially those on the blood-vessels and nerves, so 

 that when a structure is being followed forwards or backwards in the charts it can be 

 seen by a glance at the tables what muscular region of the body is being traversed. I 

 have excluded the tendons, when present, and hence the figures only relate to the belly 

 of the muscles. R = right, L = left.
