Capt. C.F. E. Andersen "Hogumau no.s" 117 no.32 Phocena n.sp.? June 18/10 Ribarea This porpoise was not seen by me until the 22nd having been killed four days. The station master had the intestines removed, by cutting down the median line of the belly. The rest of the specimen remained intact until my return, when I photo- tographed, measured & described it. I have compared the specimen, point by point with Tove's figure of Phocena dalli published in this "Delphinidae" and find the following differences. 1. The white area on the sides of P. dalli begins anteriorly about opposite the anterior edge of the dorsal fin. In this specimen the white side area extends forward to a point slightly beyond anterior the insertion of the pectoral fins. 2. In P. dalli the upper edge of the white area is almost on a line from the corner of the mouth to the pectoral. In this specimen, the upper edge of the white area is considerably above such a line. 3. In our specimen the lower edge of the peduncle, just anterior to the pectoral inserted there is a patch of gray marked with short horizontal black lines. This
