✦ Synopsis

FIVE FIGURES

Some short-fibered non-striated muscles show propagated action potentials, as the Phascolosoma probiscis retractors and the Thyone lantern retractors; others fail to propagate, as the long body wall retractors of Thyone (Prosser, Curtis and Travis, '51). I n the non-propagating muscles, contraction occurs only in the region of stimulation. Propagation in the Phascolosoina proboscis retractors is by intrinsic nerve fibers which appear to activate many muscle fibers successively (Prosser arid Melton, '54). The present paper deals with the innervation of a non-propagating smooth muscle, the long body wall retractors of T h y o n e briareiis (Lesuenr).

## Abstract Cathepsin A has been demonstrated in cod muscle. Cathepsins A and D were partially separated and purified from cod muscle. Cathepsin A and D are essentially similar to those from other sources. Cathepsin A acts optimally on the synthetic substrate CBZ‐α‐L‐glutamyl‐L‐tyrosine at pH 5.0,
