adult male taken on the island b}^ a Mr. Romenij, of Singapore/' The 

 occurrence of this animal on Batam was recorded by Mr. R. Lydekker 

 in The Field, Auj^ust 18, I'JOi/^ but apparently under the misunder- 

 standino" that this locality is part of the Malay Peninsula, an error 

 repeated in a recent number of Nature. *■ The mistake is unfortunate, 

 as no member of the S>ix harljatns gi'oup is at present known from an}^ 

 part of the mainland, and the evidence that we now have, particularly 

 Doctor Abbott's information that tlie Singapore hunters have never 

 found Siis o! elsewhere than on Batam,'' tends to indicate that no such 

 pio- occurs north of Sinoapore Strait. The essential part of Mr. 

 Lydekker's note is as follows: 



I have received from Dr. H. M. Ridley, superintendent of the Botanical Gardens 

 at Singapore, two photographs of a wild boar recently shot by Mr. T. C. Romenieg 

 in Pulan Battam, ten miles south of Singapore, which appear to indicate a species new 

 to the Malay Peninsula. These photographs clearly show that the pig in question 

 belongs to the long-nosed group represented typically by Sus verrucosus of Java, and 

 Sus barbatus of Borneo. The animal is, however, identified by Mr. Ridley with the 

 Sumatran representative of Sus barbatus, which an American naturalist, Mr. G. S. 

 Miller, has recently described as a distinct species, under the name of Sxs oi, from an 

 abbreviation of the native term "nang-oi" . . . As Doctor Volz remarks [Zool. 

 Jidirb., Abth. Syst., XX, p. 535, July 14, 1904], the discovery of the so-called /S'w.s- oi 

 in Sumatra rendered the range of Sus barbatus coextensive with that of the orang- 

 utan. Now that S. barbatus is known to occur in the Malay Peninsula, one can not 

 help wondering whether there is any possibility of theorang turning up in that area.

While only VI specimens were procured (1> on Pulo Ungar, 2 on 

 Pulo Sugi Bawa, and 1 on Great Karimon) the Rhio form of the Sas 

 'vlttatus group is abundant throughout the archipelago. A single 

 immature female (No. 113034, August 25, 1901) from Linga I am 

 unable to identif}^ satisfactorily as it is too young for the characters of 

 the skull to be definitely shown. 



« While visiting the IT. S. National Museum in June, 1904, Doctor Abl)ott said: 



"Up to the present time aljout twenty-five to thirty of this species have been taken 

 on Batam, mostly by Mr. Romenij; some by Mr. Maw. 



"Batam is largely open ground; pineapple plantations, etc., with small patches of 

 jungle, and is therefore easily driven with men and dogs. It is the only island in 

 the Rhio Archipelago which could be shot over in this way. Some very large pigs 

 inhabit Pulo Bintang, which are doubtless Sus oi. The mounted specimen in the 

 Singapore Museum was shot by ]Mr. Romenij, but it is not any of those whose photo- 

 graphs were seen by Lydekker."
