238 SOME CHINESE VERTEBRATES. 



The dimensions of the skulls of Nos. 7834 and 7835 are respectively: great- 

 est length, 62.8, 49.8; basal length, 57.5, 46; palatal length, 28, 22.6; interorbital 

 constriction, 14.5, 11.8; zygomatic breadth, 33.5, 25.5; mastoid breadth, 30.8, 

 22.3; length of mandible from condyle to tip of incisor, 36.5, 28; upper tooth 

 row from back of molar to front of canine, 19, 15.4; lower tooth row from back 

 of molar to front of canine, 22.6, 18. 



LUTREOLA SIBIRICA (Pallas). 



Three males and a female of this mink were taken at Ichang, Hupeh. They 

 appear to agree in size with measurements given for more northern examples 

 and the adult male skull seems identical with that from Chefoo, figured of natural 

 size by Milne Edwards in his " Recherches," except that the pterygoids may 

 be longer than there shown. The dimensions of these specimens, as noted by 

 the collector are: 



The cranial measurements of tf 7105 and 9 7106 are respectively: great- 

 est length, 65.5, 55; basal length, 60, 51; palatal length, 29, 23.2; length of 

 audital bulla, 19.7, 17.5; zygomatic breadth, 34.4, 26.8; mastoid breadth, 30.5, 

 24; mandible from condyle to tip of incisor, 39, 30.6; upper tooth row from 

 back of molar to front of canine, 19.5, 16; lower tooth row from back of molar 

 to front of canine, 22.8, 18. 



In the female, No. 7106, the lower first incisor on the left side is so reduced 

 as to be hardly more than half the width of its fellow on the opposite side. 



Swinhoe (1870, p. 624) records this species from Tientsin, Amoy, south 

 China, and Formosa and states that it lives in the walls of houses, in most of 

 the Chinese towns, feeding on rats and snakes. 



Matschie {1908, p. 150) has described Lutreola stegmanni from Kiaochow 

 on the Shantung Peninsula from four skins without skulls. Our specimens agree 

 more or less with his description and may be referable to this form if it prove to 

 be sufficiently characterized. 



MARTES FLAVIGULA BOREALIS (Radde). 



A perfectly typical skin of this race was obtained from the Chinese traders, 

 probably from Hupeh or to the northwest.
