394. Messrs. H. C. Robinson and C. B. Kloss on 



Tioman specimens are darker than those from Tinggi, 

 and the type from the latter island was an abnormally large 

 solitary male with the sagittal crest unusually well developed. 



Pithecus bintangensis. (Vol. II. p. 246.) 



Specimens from Batam and Bintang can be exactly matched 

 by others from the mainland of the Peninsula. 



The two islands are separated by a Strait not broader than 

 five or six miles with intervening islands. 



Pithecus karimoni. (Vol. II. p. 227.) 



The measurements given by Dr. Elliot (viz., total length 

 906 ; tail 432 ; foot 152; ear 35) are not those of the 

 collector, as they are stated to be, but should read — total 

 length 956; tail 482; hind foot 125 ; ear 35. 



The alteration of these dimensions is quite unwarrantable, 

 the more so as the result is to force the species into the 

 author^s subgenus Neocel/us, and thereby separate it sub- 

 generically from the mainland macaque, which, to anyone 

 who has examined the skins and skulls or is acquainted with 

 the animals in life, is absurd. 



Pithecus alacer. (Vol. II. p. 226.) 



In this species also measurements are not those of the 

 collector, and the total length should read 844 and not 

 794 as given by Dr. Elliot. When he comes to deal with the 

 common Crab-eating Macaque of Burma, Tcnasserim, and 

 the Malay Peninsula, Dr. Elliot has created even greater 

 confusion. 



For the mainland form of Burma and Tcnasserim he has, 

 following Cabrera, revived Cuvier's name Macucus irus 

 (Vol. 11. p. 229 j, the type of which (though it is not actually 

 so stated) probably came from Malacca. 



The range of this form he gives as Burma, Arakan, 

 Tcnasserim, and Malay Peninsula. 



Since Bonhole's paper, writers on Malayan mammals have 

 used the name fuscicularis for this race, the type of which 

 came from Suuialru; but Dr. I] ill ot restricts it to Sumatra 

 and, mirubile dic/ii, the islands Tei'utau and Langkawi 

 (Vol. 11. p. 233), which arc well within the ten-fathom line in 

 the immediate ncighbouihood of the Peninsula coast, while 

 there is over 25 fathoms with wide stretches of sea between 

 them and Sumatra.
