Fig. 1 represents the type specimen seen from above, reduced to a little more than two-fifths natural size. I have carefully compared the measurements of the exterior given by Waterhouse with Dugnid's measurements of L. acntus,* and with my own measurements of the type-cast of Professor (Joyie's L. perspi- cillatus but find no correspondence between them. Compared with L. perspiciUattis (which I regard as identical with L. acutus), Fitzroy's dolphin appears to have a smaller dorsal fin, mtnated farther from the extremity of the snout; and longer pectorals also relatively farther from the extremity of the snout. The shape of the head and the pattern of coloration seem to be very different. This species cannot be properly studied until more specimens have been obtained. LAGENORHYNCHUS THICOLEA Gray.
