The young pig has a general colour which resembles 

 »brownish terra cotta» (Oberthur: 322, 1), somewhat coar-

With regard to colour-pattern nothing hinders these spe- 

 cimens to be referred to F, t. instahilis Allén, but the skull 

 of the last specimen proves to be too young to be used for

 all sutures open. The nasals are only 37 mm. 



The dimensions of the female skull of ^s/^ igig ^re re- 

 corded below. The relation between the length of its nasals 

 and the occipitonasal length is as 35 to 100, and the rela- 

 tion between the greatest anteorbital breadth and the occi-
