K. K. K. 348#4 skeleton taken 10 a.m. 15 No. 3 Killer (Orca orca) ♀ Apr. 8/10 Oshima struck, d, I was given time to photograph & measure carefully this specimen and also to com- pare it with the figure given by True in his "Delphinidae" a copy of which I had with me. His figure is excellent and could hardly very be improved upon - only a few trifling- otant details (illegible) which the specimen differed from the figure. Color Body General color black - by pulling off one layer of the epidermis the color below was seen to be very dark neutral tint which is probably the color in life. An elliptical white spot running fore & aft on side of head. The anterior point of this spot (illegible) projects two four cent. infront beyond eye and about five cent. above it; the length (long- studinal) of this spot was 60 cent. - its greatest breadth was 17 cent.
