and S. Miiller^, which resembles it in the great transverse develop- 

 ment of its skull, the verticality of its forehead, of its occiput, and 

 its temporal fossae, in the height of its zygomatic arch, and 

 specially in the remarkable height and massiveness of its lower 

 jaw. There is no doubt that Sus celelensis is very closely allied to 

 Sus verrucosus, having not only the same general facies but the same 

 peculiarities, though on a smaller scale, as those whence the Java 

 pig has taken its name. The chief point of difference which 

 Riitimeyer points out between the figured Sus celehensis and the 

 Berkshire breed depends upon the artist^ I apprehend — being, as it 

 is, a greater length of the molar series, which, however, consists of 

 eight teeth in the figure of 8us celehensis (Verhandlungen, pi. 28 

 his, fig. 3) ; and it is possible enough that the young of Sus celehensis 

 (the contrary not having been definitely recorded) may be like the 

 young of Sus verrucosus in not being striped, and that they may 

 thus have resembled the young of the Irish greyhound pig, as when 

 old they actually do resemble it in the development of the man- 

 dibular warts. 



As regards the skulls oi Sus verrucosus, figured tab. 32 by Miiller 

 and Schlegel, the lacrymal in fig. 4 appears to have the favourable 

 relation of length to height which is characteristic usually of the 

 other Suidae with facial warts ; whilst in fig. i, which was taken 

 from a very old individual, the height and length would appear to 

 be subequal, as in the skull (fig. 6) of Sus vittatus, on the same 

 plate. I should have set less store by this variation in the two 

 drawings than I do, if Nathusius had not distinctly recorded 

 (p. 179, I. c!) that this latter is the relation in the Sus verrucosus 

 skull in his possession. On the other hand, all the undoubted Sus 

 verrucosus skulls which I have been able to measure have presented 

 the elongated form of this bone ; and the closely allied species Sus 

 celehensis, as figured in Miiller and Schlegel's fig. 3, tab. 28 his^ 

 may or may not have the long lacrymal usual in that pig. But, 

 on the whole, I should certainly accept the position that the elonga- 

 tion of the lacrymal was not constant in Sus verrucosus^ though it 

 has been so in the skulls I have seen ; and with this position I 

 should hesitate to assign to this peculiarity all the value which 

 Nathusius's insistence might lead one to assign to it. 



Taking, in the second place, this variability in the proportions of 

 the lacrymal bone, and coupling with it, first, the absence of striping
