 [Very common on Bintang, Batam, Sauh and Kundur iHlaadH, but 

 apparently not on Karimon. Very destructive to pine-apple phiutu- 

 tions on Batam and Sauh, and according to the natives verv Ixdd.und 

 not easily scared away from the gardens. Unfoi-tuuately, we never met 

 with any of these courageous pigs, and as a result, the ctilleetion i>nlv 

 contains one specimen, which Avas shot grubbing alx)ut on the ni-f at 

 low tide.— H. C. R. and C. B. K.J

The teeth of this specimen agree closely allowing for sex with the 

 figure given by Mr. Miller of his type. Its parietal constriction, how- 

 ever, is 29 mm. across, a breadth considerably in excess of those record- 

 ed by Miller ; no doubt the discrepancy is partly individual and partly 

 due to immaturity. 



[The " babi bakau," or Mangrove Pig, which includes both thin and 

 the succeeding species, is probably commoner than Sus oi in the Khio 

 Archipelago. It is a reef feeder, found on the sh"»iv in druves «>f ei^dit 

 or nine, and is also common in coconut and pine-apple plantations. —
