Abstract
1. The fine structure of tortoise skeletal muscle has been studied with the electron microscope.2. The packing of the A filaments (1·6 μ long) and the I filaments (2·35 μ long) within the myofibril is similar to that in frog twitch fibres.3. The position of the N line within the I band is found to vary with the sarcomere length.4. The T‐system tubules in these muscles form a three‐dimensional network across the fibre at the level of the I band. On either side of the Z line it forms triad relationships with the other network of tubules of the sarco‐plasmic reticulum.
