subspecific-ally sejjaralile from the Soathern forms. ;The comparison of Mr. 

 Harris's largest bull from (iiiadaloupe Island with my Falkland Island specimen, 

 two or three Macqnarie Island specimens, and (wo or three Crozet Island individuals 

 makes it at once apparent, as is also shown in photographs from life, that the 

 proboscis of the Northern Sea Elephant is much longer than in the Southern 

 races. This is especially remarkable in young bulls. A Northern bull at Trin"-, 

 II ft. 4 in. long, has a trunk :5i— 4 in. long, while a l"2-foot bull from the 

 Mac(|naries has no sign of a trunk. The trunk, however, was apparently very fnllv 

 developed in the e.xtinct Bass Straits race, and is also longer in the Macqnarie form 

 than in the Crozet and Falkland races. 



The measurements of my Falkland Island bull are by iar the largest of any 

 preserved Sea Elephant in collections, its total length over t!ie curve being '-.'1 ft. 

 From what I can gather from my e.Kamiuation of material the following forms 

 will eventually be distinguishable : — 



1. Mirouuga leonina leonina (Linn.). 

 Coasts of California and adjacents islands (wintering on Chilian coasts). 



~. M. leonina patagonica Gray. 

 Falkland Islands, S. Georgia, and ? S. Shetlands. 



3. M. leonina kerguelensis (Peters) = M. I. crozettensis Lyd. 

 Herd Island, Kerguelen Island, Crozet Lslands, etc. 



4. M. leoninus peronii Gray. 

 Islands of Bass Straits (extinct). 



5. M. leoninus macquariensis Lyd. 

 5Iac(juarie Islands.
