528 Dr. C. I. Forsyth Major on 



To iudge from the short description of tlie skulls and den- 

 tition and from the figures — unfortunately no measurements are 

 g-iven, — none of these four '' species " can be separated from 

 Nehring's 8. celehensis var. phiUppensis. 



In applying the criteria for specific distinctions resorted to 

 by P^re Heude to the crania of the Indian " Sus crt'status " in 

 the Natural History Museum, from 12 to 15 different species 

 of Indian Wild Boars might be easily distinguished. We 

 must, however, be grateful to the author for showing us the 

 amount of variability in these forms, even those from the 

 same island. 



The skull of " S. cehifrons,''^ from Cebu *, conveys the 

 impression of being that of a more or less domesticated 

 animal, possibly a cross with a domestic pig — a not unfrequent 

 occurrence in those islands, according to P^re Heude's state- 

 ment t- 



Of " Sus minutus " :}:, distinguished by its small size, the 

 very simple structure of its molars §, and the large size and 

 elevation of premolars ||, which characters distinguish it from 

 mindone'nsis, no habitat is given in the description ; but I 

 understand, from what is said incidentally 1[, that it occurs in 

 Mindanao — so that there seem to be two forms of wild pigs 

 in ]\Iiiidanao. 



Of " S. calamianensis " we sliall have to say something 

 later on. 



2. Sus verrucosus amhoinensts, subsp. n. 



There are two skulls (both males) of the Wild Boar of 

 Amboina (a small island to the south-west of C'Cram) in the 

 Natural History Museum, 59.ri.4.6 (1362 c) and 59.6.4.5 

 (1^562 d) ** ; both were collected by A. R. Wallace, and figure 

 in the catalogues under the head of 5. vitiatus. Polleston 

 was aware that the skull 1362 d is a "aS'm5 verrucosus''^ ft, but, 

 by a strange inadvertance, he mentions on the opposite page
