the latter however are characterized by having no hands or 

 stripes at all on the body, in which characteristic they 

 differ from all the other hitherto known Pigs from the 

 islands of the East-Indian Archipelago. Dr. Forsyth Major 

 (Ann. and Mag. N. H. 1897, p. 531) said that he expected 

 that the "wart" supported by the crest and the nasal 

 rugosities of vemicosus will be found to be missing in 

 females and young individuals of the uerrwcosus-group. 

 Evidently he never had seen a female-specimen at the 

 time he wrote his paper »on Sus verrucosus Mull, and 

 Schleg., and allies, from the Eastern Archipelago". 



In the »Verhandelingen a. s. o.. Tab. 32, figs. 1, 2, 3 

 and 4, there have been figured two skulls as skulls of 

 Sus verrucosus; 1 and 2 represent a very elongate skull, 

 labelled as having been collected by Diard in Java, slender 

 in shape, with a well-developed crista, meanwhile 3 and 4 

 are figures of a much shorter skull, broader and not elegant, 

 sides of future crista widely apart. Do these two skulls 

 really belong to the same species? Apparently Muller and 

 Schlegel have been struck also by the different shape of 

 these skulls, for which these authors gave the following 

 interpretation. I.e. p. 176: »the skull (of Sus verrucosus), 

 "especially in very adult specimens, is much more oblong 

 "than in Sus vittatus. The orbits are smaller; the jugal 

 "bones stouter and more outward curved ; the excavation 

 "on the sides of the skull, wherein the muscles of the 

 "snout are fixed, is more oblong and deeper; and the skull, 

 "especially in old specimens, is more or less impressed 

 "above opposite the posterior part of the named excavations. 

 "Finally is the distance between canine and molars much 

 "larger than in Sus vittatus. The metamorphosis by age 

 "in the shape of the skull of this species {Sus verrucosus) 

 "is very great, caused by the oblong form growing with 

 "advanced old age. One may understand these metamor- 

 "phoses by comparing our figures of both skulls, of a 

 "tolerably old (Tab. 32, figs. 3 and 4) and a very adult 

 "skull (Tab. 32, figs. 1 and 2). Moreover in this species, like
