SIZE. 279 



In the foetal specimen the pelage is longer, and very soft to the 

 touch, feeling like fur, but is simply soft straight hair, not at 

 all like the underfur of the Fur Seals, or even the first coat of 

 Callorliinus ursinus, under the long soft hair of which is an 

 abundance of soft silky underfur. In the foetal Zalophus a 

 very slight admixture of fine curly underfur can be detected on 

 close inspection ; but in no sense is the first coat in this species 

 comparable, in respect to underfur, with the first coat in the 

 Fur Seals. In the older specimens of Zaloplius, above described, 

 which have already acquired their second coat, the pelage is 

 still longer and softer than in the adults. 



SIZE. I am unable to give the dimensions of very old males* 

 A male (M. 0. Z. Coll., No. 5786), in which the crests of the 

 skull are well developed, and the teeth slightly worn, but which 

 is evidently only middle-aged, gives the following measure- 

 ments : Total length from nose to end of tail* 2160 mm. ; to end 

 of outstretched hind-flippers, 2542 mm. (collector's measurement 

 from fresh specimen, U 8 ft. 4 in."); hind foot (from body), 

 380 mm.; fore foot (from axilla), 360mm.; tail, 110mm; ear, 

 35 mm. ; longest whisker, 225 mm. The collector gives the girth 

 behind the axilla as 1337 mm. ( U 4 ft. 5 in."). Another speci- 

 men (M. C. Z. Coll., No. 5789, young male), with the crests of the 

 skull wholly undeveloped, gives a length from nose to end of tail 

 of 2140 mm. ; to end of outstretched hind limbs, 2480 mm. (col- 

 lector's measurement from fresh specimen, " 8 ft. 2 in.") ; hind- 

 flipper, 340 mm. ; fore-flipper (from axilla), 370 mm. ; tail, 80 mm. ; 

 ear, 3.3 mm. ; longest whisker, 190 mm. The collector gives the 

 girth behind the axillae as 1220 mm. (" 4 ft."). 



A fully-adult female (M. C. Z. Coll., No. 5787) gives a length 

 (from tip of nose to end of tail) of 1800 mm.; to end of out- 

 stretched hind-flippers, 2054 mm. (collector's measurement from 

 fresh specimen, U 6 ft. 9 in."); girth behind axillae, 1247mm. (col- 

 lector's measurement, "3 ft. 9 in."); hind-flipper, 270mm.; fore- 

 flipper, 310 mm.; tail, 70mm.; ear, 30 mm.; longest whisker, 

 110 mm. 



Another adult female (M. C. Z. Coll., No. 5788) gives the fol- 

 lowing : Nose to end of tail, 1570 mm. ; nose to end of outstretched 



* This measurement is by estimate based on the collector's measurement 

 of the total length to end of outstretched hind-flipper, taken from the fresh 

 specimen, the calculation being based on a study of the skeleton. The 

 total length of head and body, as taken from the mounted specimen, is 

 obviously much too short.
