622 On rare Species of Larvivora from China. 
this collection, because the Tsin-ling Mountains appear to be 
the southern boundary of a number of Palearctic species. 
The district is evidently rich in species of the genus Larvi- 
rord, a section—if separable at all, and certainly, so far, of 
doubtful limitation—of the genus Hrithacus, as accepted in 
the ‘ Catalogue of Birds.’ 
Three species of Larvivora are represented in this col- 
lection :— 
1. LARVIvoRA OBSCURA. 
Larvivora obscura Berez. & Bianchi, Aves Exped. Potanin. 
Gansu, p. 97, pl. 1. fig. 2 (1894: Kansu). 
This rare bird was hitherto only known from the single 
adult male obtained by Berezowski. The present collection 
contains four males only, shot in May and July on Mt. Tai- 
pai-shan “halfway up.” There can be no doubt that the 
species belongs to the genus Larvivora. The female is not 
yet known. 
2. LARvivora Davipi. 
Calliope davidi Oustalet, Bull. Mus. Paris, 1892, p. 222; 
Arch. Nouv. Mus. Paris, Mém. ser. 4, iii. p. 271, pl. xi. 
(OOM): 
Eight specimens of this remarkable bird had been sent to 
the Paris Museum from Ta-tsien-lu in Szechuan. If the 
genera are separated, L. davidi doubtless belongs to Larvivora 
and not to Calliope, though it has a red throat. Our col- 
lection contains one ma'e and one female of ZL. davidi from 
Tai-pai-shan, shot “halfway up” on July 6th and 10th. 
Neither ZL. obscura nor L. davidi, though undoubtedly 
Palearctic forms, have been mentioned in Dresser’s ‘ Manual 
of Palearctic Birds.’ 
3. Larvivora ruFicers. (Plate XIII.) 
Larvivora ruficeps Hartert, Bull. B. O. Club, xix. p. 50 
(eb. 1907: Tai-pai-shan), 
Of this fine new species three males and one female were 
obtained in July (10, 12, 13, 15. vii. 1905) “ halfway up.” 
I have deseribed the male (/. c.) as follows :—
