238 LILLJEBORG ON THE 



Nilsson in the report previously quoted, and deposited by him in the Zoological Museum in 

 Lund, where it is now preserved. The height of the body under the dorsal fin is, according to 

 the sketch, somewhat less than that of Orca Schlegdii as given by Schlegel. Its entire length 

 is about 4i times its height ; but in the latter it is less than 4,i times, according both to the figure 

 and to the description by Schlegel. The hinder part of the body from the anus is, on the con- 

 trary, less slender and elongated. The height of the body above the anus is contained 7 times in 

 the entire length, while this height in the latter is contained nearly 8 times in the length. The 

 most striking characters, however, are that the dorsal and pectoral fins are considerably larger, 

 and that the latter are obtuse and the former almost straight. The vertical height of the former 

 is considerably greater than its length at the base (exceeding it by 0. while that of Orca Sclilegelii 

 is less than its length at the base, according to Schlegel's figure, as well as to an outline sketch of 

 the same fin of the specimens obtained at Bergen, fm-nished me by Dr. Koren. This height is 

 contained about 6 times in the length of the body. The length of the pectoral fins from the 

 hinder angle at their base (" hintern Ausschnitt," Schlegel) is not contained quite 5^ times in the 

 length of the body, while, in the latter, it is contained more than 8 times in the length. To the 

 above-stated difference of colour may be added that there is a similar smaller spot close in front of 

 the large white spot above and behind the eyes.

The front of the head {nose) short, rounded, with a prominent hemispherical convexity or "fore- 

 head." In the skull, each of the intermaxillary/ bones are, on the upper side of the beak, much wider 

 than that part of the maxillary which is visible at their outer side.

In length it reaches 20'. Form of body tolerably elongated, with the greatest thickness in front 

 of the middle, the fore part short and thick, the hinder part rather elongated and narrow. Nose 

 very short and rounded, and the head above the nose enlarged and hemispherically rounded. 

 The fins are large. Dorsal fin, about the middle of the body, directed backwards. The greatest 

 thickness of the body is at the beginning of the dorsal fin. The greatest circumference of a speci- 

 men 19'— 20' long was, according to statements by Lemaout (also made by F. Cuvier) 10'
