The discoverers of South Georgia called these animals »Sea-lions» but added 

 that it was the kind described by Lord Anson and this proves that it really was 

 Anson's »Leo marinus» and LiNNiEUs' »Phoca Leonina» (»capite antice cristato»). 



Concerning the size of these animals certainly exaggerated measurements have 

 found their Avay into the literature. 



Von den Steinen (12) has recorded the length of an adult bull of Elephant- 

 seal to about 5 m. and of a cow to about 3 m. 



Sörling has recorded the following measurements of Elefant-seals in flesh, 

 just killed: 



J ad. 9 / G 01 



Distance from snout to tip of tail 4,85 m. 



Distance from snout to end of hind-flippers ... 5, 5 o ra. 

 Distance from snout to anterior börder of axilla . 1,7 5 m. 



Interorbital breadth 25 cm. 



Distance from snout to anterior corner of eye 1 . . 27 cm. 

 Distance from anterior corner of eye to ear-opening 17 cm. 



Greatest breadth of snout 35 cm. 



Distance from snout to corner of inouth 38 cm. 



Distance from tip of lovver jaw to corner of inouth 23 cm. 



Breadth of head at kind margin of eyes 33,5 cm. 



Breadth of head at ear-openings 60 cm. 



Circumference of body just behind fore-fiippers . . 4,15 m. 

 Circumference at root of tail 1,1 o in. 



This shews the striking difference in size between the sexes. 



The colour of the quite young calfs was very dark almost black. In No v. — 

 Dec. the old bulls and cows, when dry, had an oily greenish grey colour, the young 

 bulls were more greenish yellow. When the bulls returned in Febr. the}^ were shed- 

 ding the hairs and looked then dark rusty brown. After shedding the colour became 

 first yellowish grey and then gradually passed into the oily greenish grey coat. The 

 shape of the snout is the most characteristic of this animal. In young specimens 

 it is so to say normal (Pl. III fig. 7) then it increases in size with age (Pl. IV fig. 

 17 & 15) and finally it becomes an inflatable proboscis which in rest is puckered up 

 in three portions on the back of the snout but can be inflated as Pl. III fig. 6 

 shows or be allowed to häng loose and lax as in Pl. IV fig. 16. The temperature of 

 the blood of an Elephant-seal Sörling measured to be + 35° C.
