126 seen in schools of five or six. They shimmred along the surface frequently, but did not leap entirely out of the water as I have seen D. delphis do so often. On the day following the capture, I saw several more schools of the same species. The gunners tell me that they see this porpoise frequently and it would seem to be abundant. P. borealis has also been reported as abundant by the gunners. Color A line of dark gray 10 mil. wide runs from the corner of the mouth in a curve down to the ant- s rior insertion of the [illegible] pectoral fin. It begins again at the base of the fin above, 40 mil. from the posterior insertion, curves slightly upward and then downward, upward again in a long sweep, & finally downward running off the peduncle 5-0 mil. behind the anus. The line comes down furtherest on to the belly 1-6-0 mil. from the post. insertion of the fin.
