978 MR. OLDFIELD THOMAS ON [DeC. 15, 



was found rather common in the bottoms of certahi narrow, 

 wooded and bushy gullies. They, in company with A'podemus 

 speciosus, bui-row in the soft loose soil beneath the bush." — JI. P. A . 



26. Craseomys shaxseius Thos. 



S. 1931. $. 1932, 1933, 1934, 1935, 1942. Mountains 

 12 miles N.W. of Ko-lan-chow, Shan-si. 7000'. 



Practically topotypes of this striking species, described from 

 Mr. Anderson's previous collection. 



The summer fur is hardly shorter than that of wintei", and is 

 quite similar in colour and texture. 



" Much less common than the last, but like it found in the bush- 

 overgrown gullies and canyons." — M. P. A. 



27. Myospalax fontaxieri M.-Edw. 



<S . 1733. Ordos Desei-t, 8 miles N. of Ching-pien, Shen-si. 

 4900'. 



S . 1916. Mts. 12 miles K.W. of Ko-lan-chow, Shan-si. 7000'. 



cJ. 1966, 1973, 1997. $. 1965, 1996, 2001. Ning-wu-fu, 

 Shan-si. 6000'. 



(5. 1988. $. 1980, 1994. 20 miles S.W. of Ning-wu-fn, 

 ;Shan-si. 6600'. 



These specimens all agree in possessing some evidence of the 

 white face-markings figured by Milne-Edwards in his type, but 

 believed by him to be inconstant. He may have mixed up with 

 M.fontanieri examples of the next species, in which the white 

 crown-streak is rarely present. 



Specimens of the remarkable Mole-rats of this genus are 

 exceedingly rare in Musetnns, so that this fine series of a species 

 new to the Museum, and those next referred to form a most 

 valuable accession to the Museum collection. In addition we have 

 lately received from Mr. E. B. Howell some examples of 

 M.psilurus M.-Edw., so that the Museum now possesses examples 

 ■of every described species of the genus, including really good 

 .series of the two now obtained. 



28. Myospalax cansus Lyon. 



Myotalpa cansus Lyon, Smiths. Misc. Coll. 1. p. 134, 1907. 



5 . 1729, 1730. Yen-an-fu, Shen-si. 3000'. 



S. 1794, 1795, 1800, 1811, 1816, 1817, 1819, 1821, 1828, 

 1838, 1849, 1850. $ . 1751, 1791, 1796, 1797, 1812, 1820, 1822, 

 1827, 1837, 1839, 1840, 1841, 1847, 1852. Yu-lin-fu, Shen-si, 

 4000'. 



This species diflfers from the last mainly in size, the largest 

 .skull, which agrees closely with the figure given by Mr. Lyon, 

 being 45*3 mm. in condylo-basal length. Face-markings are less 

 developed, only five out of 28 specimens having small frontal 

 streaks, while the bufiy nose-patch is small and often almost 

 ■obsolete.
