and separate it from the true M. flavigida according to Mr. J, L. 

 Bonhote in Ann. & Mag, Nat. Hist. ser. 7, vol. xii. p, 342 et seq. 

 (1901), who there reviewed the grouj). 



Since writing the above paper Mr. Bonliote has recorded two 

 examples of the true M. f. jlavigula from Chiengmni, Northern 

 8iam (P. Z. S. 1902, part i. p. 38), thus increasing the range of 

 this form. These examples are much larger than the individual 

 nnder discussion here, so that it would appear that there are in 

 fSiam two races similar in colour but differing in size and in the 

 characters given above. Were it not for these latter it would be 

 most convenient to regard the south-eastern animal simply as a 

 small race of M.Jlavigida.

These animals are intermediate between T. helangeri Schreb., 

 of Pegu and Tenasserim, and T. concolor Bonhote, known from 

 Southern Annam and Cochin-China. On the whole, however, 

 they most closely approximate to the latter, though the pale 

 shoulder-stripe is perhaps a little more marked, and so I have 

 assigned them to it on geographic grounds. Several of them 

 which are faintly washed on the rump with ochraceous, nearly 

 resemble examples of T. belangeri from Southern Tenasseiim, but 

 the annulations anteriorly are somewhat coarser, while the buft' is 

 of a slightly deeper shade. There are three pairs of mammae as 

 in T. helangeri ; in T. concolor the number is unfortunately un- 

 known, as are the external measurements. The present animals 

 are somewhat lai'ger than T. helangeri, while the dimensions of 

 the skulls are similar to those of skulls from Annam and Cochin- 

 China. 



Measurements. — Ears of the series, 15-20 mm. For other 

 measurements see table, p. 68.
