may have come from Pulo Condore, and one of the others has a dis- 

 tinctly small hind foot like that of the Cordore animal. See table, 

 page 70. 



Si^ecimens examined. — Six. See table, page 70. 



TUPAIA MODESTA Allen. 



1906. Tupaia modesta Allen, Bull. Amer. Mus. Nat. Hist., vol. 22, p. 481, Dec. 

 17, 1906. 



Type-locality. — Island of Hainan, off the south coast of China. 



Type-specimen. — In American Museum of Natural History, New 

 York, Cat, No. 26654, collected at Lei-Mui-Mon, Hainan, January 5, 

 1903, through agents of Mr. Alan Owston; skin well preserved, but 

 skull damaged posteriorly. 



Geographic distrihution. — Island of Hainan. See No. 4 on map, 

 on page 75. 



Diagnosis. — A geographic form of Tupaia cliinensis distinguished 

 by its generally darker coloration, externally not unlike T. concolor, 

 but distinctly smaller; mammse, 2-2 = 4. 



Color. — In general coloration Tupaia modesta is essentially like 

 T. concolor, but the underparts are more whitish, and when the hahs 

 of the tail are artificially spread only three distinct buffy annulations 

 are seen instead of five. 



Shull and teeth. — The skulls of Tupaia modesta available for exami- 

 nation are considerably damaged. Apparently they are not essen- 

 tially different from those of T. cliinensis. 



Measurements. — Type: Hind foot, 46 mm.; zygomatic width, 25.5; 

 width of brain case, 19.5; maxillary tooth row, 18. The type has the 

 largest liind foot in the series, most of the other specimens measuring 

 only 43 mm. See table, page 70. 



Remarl^s. — Tupaia modesta is quite distinct in its generally darker 

 color from most specimens of T. cliinensis, if not appearing distinctly 

 darker with reference to the upperparts, the tail and underparts 

 appear so. As to how different it is from tree shrews on the mainland 

 adjacent to Hainan it is impossible to say. The nearest specimens 

 geographically that I have seen are two from Tonkin in alcohol, 

 young, and so useless for comparison. The two Mongtsze specimens 

 are \evj dark above, but are distinctly whitish underneath. It is to 

 be observed that Tupaia concolor of the southeast coast region of Asia 

 is also a dark-colored animal, but distinctly larger than T. modesta. 



The number of mammae, 2-2 = 4, in this species and the preced- 

 ing is interesting as in all the other continental treeshrews north of 

 the Malay Peninsula, the number is 3-3 = 6. As only one specimen 

 in each species is available for determining the number of mammae, 

 too much weight can not be attached to this peculiarity. 



Specimens examined. — Seven, from various localities in Hainan. 

 See table, page 70.
