Abstract
SPECIMENS of Amphioxus caribbaeum collected while working at the Tortugas Laboratory of the Carnegie Institution of Washington were examined with respect to the amylase present in the gut. Determinations were carried out by the micro-method of Linderstrom-Lang and Holter as modified by Holter and Doyle1. The intestine was divided into three regions, namely, hepatic cæcum, proximal intestine and lower intestine. The gut was split open, washed, and the area of each piece measured. When examined for amylase activity, the relative activities per unit area were found to be: cæcum, 62; proximal intestine, 41; lower intestine, 30.
