936 DK. E. LONNBERG ON WART-HOG [DeC. 15^ 



where they were quite common and frequented chiefly the sandy 

 banks and dry reed-fences around the gardens. They are pro- 

 bably to be found all along the south coast of the Caspian, for- 

 although none was obtained during the journey along the coast, 

 from Resht to Asterabad Bay, this may be accounted for by the 

 fact that it was then early in the year, February and March, and 

 too cold. But I once or twice caught a glimpse of a lizard, among 

 the scrub on the dry sand-dunes near the shore, which I feel sure 

 now must have been this species. None was obtained on the 

 smaller western peninsula, but I should not like to say they are 

 not to be found there, for they probably are, and I expect the- 

 species exists all along the south coast of the Caspian Sea where it 

 is dry and sandy."

3. Remarks on some Wart-Hoo; Skulls in the 

 British Museum. By Dr. Einar Lonnberg, C.M.Z.S. &e. 



[Received October 19, 1908.] 



When recently describing the mammals collected in German 

 East Africa by Prof. Dr. Y. Sjostedt * I made some remarks, 

 about different races of Wart-Hogs, and, with some hesitation, I 

 expressed the opinion that " for the present at least" five such races, 

 must be " discerned and distinguished by names." Since then 

 I have had the opportunity, thanks to the kindness of Mr. Oldfield 

 Thomas, of studying the material of Wart-Hogs in the British 

 Museum (Nat. Hist.), and, thanks to the kindness of Dr. S. 

 F. Harmer, that in the University Museum of Cambridge. It was 

 quite easy to recognize among this material the five races men- 

 tioned in the paper quoted above, in such cases where they were 

 represented by skulls of adult specimens, especially boars. 



A few remarks about these skulls may be of some value for 

 future study of these animals, as I did not have access to speci- 

 mens of all five races when writing the first paper. 



Phacochcerus africanus (Gmelin) appears to be the largest or one 

 of the largest of these races. A skull of an adult boar of this kind 

 in the British Museum from the typical locality, Cape Verde,, 

 measures 440 mm. in length, but the extreme tips of the nasals are- 

 not complete, so that this measurement should be a little longer. 

 The postorbital portion of this skull is very long, measuring 59mm.j, 

 but it is at the same time very broad, viz. 58 mm. across the flat 

 area. By this characteristic Ph. africanus is very easily distin- 

 guished from Ph. celiani, which also has a long but at the same time
