3. Selenarctos macneilli (Lydekker) 
Ursus torquatus macneilli Lydekker, Proc. Zool. Soc. Lond., 1909, pp. 607-610. 
Type locality: — Ta-chien-lu, W. Ssu-chuan. 
There was no specimen of the black bear from western Ssu-chuan in 
the Sikawei Museum with which to compare those from other parts, 
but from Lydekker^s description of it it would appear to be very dis- 
tinct. The latter states that this species has smaller cheek teeth than 
the Himalayan species, and also a broader skull. It thus cannot be 
placed with mupinensis, in spite of the fact that its type locality is 
so close to that of the latter. It seems to me to represent the black 
bears that inhabit South Shensi, West Honan, and North-west Hup’eh, 
as well as Ssu-chuan. In the figure accompanying Lydekker’s decrip- 
tion the names of the two species from the Himalaya and West Ssu- 
chuan seem to have been interchanged, or else his description is wrong, 
and the narrower skull figured really represents his macneilli. The 
latter was further described as having longer and softer hair than 
thibetanus. 
Habitat: — The range of this bear is probably from West Ssu-chuan, 
eastward to West Honan and North-west Hup’eh, and north into South 
Shensi. 
4. Selenarctos ussuricus Heude 
Selenarctos ussuricus Heude, Mem. cone. THist. Nat. de TEmp. Chin., vol. V, 
p. 2, pi. II, fig. 10, 1901. 
Type: — ^An immature skull in the Sikawei Museum, Shanghai. 
Type locality: — ^The Ussuri, Eastern Manchuria. 
In the immature skull, supposed to be from Kamschatka, the upper 
posterior molar was 31 mm. in length, while in the Ussuri specimen, a 
much younger one, and probably a female, the same tooth was only 
25 mm. in length. In my specimens from Kirin this tooth was 27 mm. 
in the female, and 30 mm. in the male. As none of the skulls from 
other districts showed this tooth to be larger than 28 mm. (i.e., in the 
male from Moupin), it appears that the large size of this tooth is char- 
acteristic of the Manchurian species. Another distinguishing feature 
is the proportionate narrowness of the skull. 
From a comparison of the skulls from Kirin, the Ussuri, and Kams- 
chatka, I do not hesitate to class them together as representing one 
species, and since Heude has given the name ussuricus, accompanied 
with a figure (upper molar tooth row), though without a description, 
this name must stand.
