distinctly marked, passing from the nostrils immediately under the eye, and 

 dividing the surface of the body into nearly equal parts throughout. (In the 

 photograph the head of the male shows wholly dark, from some accidental 

 circumstance). The upper part of the head is slightly darker than the back. 

 Numerous spots and patches of black, especially on the hinder part of the 

 belly, where the black becomes predominent ; small white spots are also 

 intermingled with the black ones, especially over the hind ribs. Some of the 

 smaller spots are gTey. 



Female. 

 Considerably larger than the male, but proportionately shorter in the neck, 

 which is also thicker, giving a marked difference of figure to the fore-part of 

 the animal. External aperture of the ear distinguishable, but not so readily 

 as in the male. Colour rather lighter than in the male, with very few traces 

 of the black patches, so prevalent on the lower part of the body of the latter. 



In both male and female the teeth are perfect : and the dentition normal, 

 2 ' 1 ' 5 = 32. The description given by Dr. Hamilton of the teeth of the 



Weddellii, answers exactly for those of these seals, and I, therefore, copy it : 

 " The incisors are conical in their form, and somewhat curved inwards ; those 

 " in the upper jaw are by much the longest, and the two middle ones are 

 " placed further within the mouth than the other two, and are also much 

 " smaller " (this latter peculiarity is shared by those of the lower jaw) ; " the 

 " canines are conical, very much developed at the base, and slightly gr-ooved ; 

 " the body of the molars is composed of three parts, the central conical part by 

 " much the longest and largest, with a small tubercle on each side."

Note. — In Nos. 5 and 12, it is uncertain whether my measurements correspond with 

 Dr. Hamilton's as to the points chosen to measure from. I take No. 12 from angle 

 between tail and flipper.
