276 PROF. ROLLESTON ON THE DOMESTIC PIG 



The skull of the Sus from Teraate lent nie by Dr. A. B. Meyer belonged to a young 

 male, the third molars of which were just coming into place, and which may he supposed 

 therefore, according to the analogy of S. scrofa, var. domesticus, if that may be taken as 

 any guide, to have been about eighteen months old (see Nathusius, I. c. p. 21). It differs 

 from skulls of S. cristatus in the flatness of its lacrymo-frontal ridge, in the convexity 

 backwards of its naso-frontal suture, and in being somewhat smaller than male skulls of 

 that variety of Sus usually are. The posterior lobes of its third molars are not quite so 

 large as they usually are in S. cristatus ; but to this point I am not inclined to assign as 

 much importance as some other writers do (see Riitimeyer, 'Fauna der Pfahlbauten,' pp. 33 

 and 188, and, per contra, Nathusius, I. c. pp. 49 and 103). In the straightness of its vertical 

 contour it contrasts with «S'. celebensis, S. andamanensis, S. vittatus, as figured by Miiller 

 and Schlegel, I. c. plate 32. fig. 6, and with S. barbatus as figured here, Plate XLIII. 

 fig. 7 ; and resembles S. cristatus, as it does also in its general facies. Dr. A. B. Meyer 

 thinks that this Sus may possibly deserve to be considered a new species, S. tematensis ; 

 but having had abundant experience of the facility with which the wild pigs of that 

 region cross considerable arms of the sea, lie would, I gather, express himself with much 

 caution as to its relations to S. papuensis and the-Suidse of the neighbouring islands, vol- 

 canic and other, tenanted by swine. The colouring, however, of the head of this Sus 

 differs from that of any other Sus seen by Dr. A. B. Meyer, or figured by Schlegel — the 

 head being covered all over with long black hair, except in the region occupied by a broad 

 yellowish brown streak beginning between the eyes and descending to the snout, where 

 it broadens.
