Wo now owe to the l<in.ln."ss ..I il,.- aiitliuHtios ot th.- Unil.-.l 

 States National Museum six speciinen.s ol" tlu" ^a-oup, ivpivwntint,' 

 different forms described and recognised hj Messrs. Miller and Lvon 

 in their various writings on the subject, and have carefully couipan-.! 

 Raffles' specimens with these in order to settle, pen<ling tin' urrivaj of 

 Bencooleu topotypes, what form should be cousiilen-d to Ix; the true 

 Scmrus vittains. 



Of the four " typical " specimens, No. 79, 11, 21, 580, lias a re<l tail 

 tip, and is clearly referable to 8. v. miniatus, Miller, a native of tl»«. 

 northern part of the Malay Peninsula. No such form has Uh-i\ found 

 in Sumatra, and since Eaflles undoubtedly received many KpHnineiiH 

 from places in the Peninsula, we may consider this specimen as one 

 of them, and eliminate it as being not typical of tin- Hmcool.-n 

 viftatus. 



A second specimen, No. 79, 11, 21, 581, has lost the tip of its tail, 

 1)ut the stump shows a little red, and this also may, therefore. Iio 

 eliminated as possibly Malayan in its origin and put asidr frnni 

 the question. 



The above two specimens are referred to in Horsfu'ld's " Catalogue 

 of the Indian Museum"* as having been presented by Sir T, S. 

 Raffles, but no locality is assigned to them. 



The other two specimens, 69a and 096, were presented by I,ady 

 Raffles in 1830, and of them 69a with a broken tail and cljaracters 

 that we cannot match exactly in any Sumatran specimen may l>e put 

 aside, thus leaving 69h to stand as the type. 



This specimen agrees precisely with the two from localities nearest 

 to Bencoolen now available to us— namely, one from Pa jo in the Padang 

 Highlands, collected by Carl Bock; and the other from Tarussau IJuy, 

 collected by Dr. Abbott —and typical of Mr. Lyon's Sr. r. loniKdauuf.^ a 

 name that will, therefore, become a synonym of Sr. v. riltaliig. 



This result is not unexpected, and there is littj.' prospect of its 

 being upset on the arrival of undoubted Bencoolen spociuiens of iSV. 

 vittatiis. 



We, therefore, take the name viftatus for the PlaTitain S«]uirr<«l of 

 the southern half of Western Sumatra, heaving prniiiHulariM for thos*» 

 of the Peninsula and Eastern Sumatra, with the niiijority of tlio 



islands between the two. That fi i Batam. howev.T. may l« di«tin- 



guishcd as a special local form.
