.slMMAJiY OF THE INDIAN MAMMAL SURVEY. r,",: 



represent tax albino oi" some form of Ceylon monkey, probal)ly 



either Icophnlo^tienis or ursinus. Still as this is also the genotj'pe 



of PiTUKCTS (Thomas, A. ;M. N. H,, xvii, p. 179, 191C), I propose 



to retain it for the present among the species in my ke3\ J Myth 



in his original description oi hdrhci (J. A. S. B., xvi, p. 734, 1847) 



gave the type locality as the Ye Province of Tenasserim, bnt in 



I860 (Cat. Mamm. Mns. As. Soc, p. 48) he corrected this, on the 



authority of the collector, 31. liarbe, to "interior of Tipperah 



Hills'". After carefnl consideration I decided (J. B. N. H. S., 



XXV, p. 40, 1917) to adopt, at any rate provisionally, the 



Tenasserim Uionkey as the representative of harbei. 



This species forms a fom'th section of Blanford's key, viz., C. b., 



-T ^A •? J in where it represents the Assam langui's. 



^ ■' in 1910 (J. B. rs. H. b., XXIV, p. o54), 



1 stated that the name jnlentas was inadmissible for a langiir ; I fear 



I was mistaken. As now advised, I must withdraw that statement 



and conseqiiently my name f?/ov/a must fall, as a synonym oi inleatus, 



Bl}'. I may note here that 1 have been successful in tracing the 



type of arge7itatus, Horsf. (Cat. Mamm. E.I.C. Mus., p. 7, 1851), 



ranked by Blanford as a synonym of phaiirei, and it too proves 



to be jiileains, Bly. At the same time that I described diirga, I 



proposed the i\a,me hrahma for the langur of Upper Assam. Finally, 



in dealing with the Chindwin Collection I had already described 



shm'tridijei (J. B.N. H. S., xxiv, p. 56, 1915), but the subspecies 



belli(jer, then proposed, cannot stand, for Mr. Shortridge assigns its 



difference in colour from skortridijei, its chief characteristic, to an 



effect of wood smoke while drying the skins of the specimens. 



Thus the following must be substituted for iiileaias in Blanford's 



list, viz., pilecdus, Bly., Lower Assam ; brahma, Wr., Upper Assam ; 



and skortridijei, Wr., Upper Chindwin. 



These two species represent section C. c. of Blanford's ke}', i.e., 



,, ^,-, , . Til the crested langurs. The second is

allowed to drop altogether. The langurs as thus altered may be 



arranged in a key as follows : — 



' Keij to the species of Pithecus. 



I. Hair of crown radiating from one or more 

 points on the forehead. 

 J. — Hair of crown radiating from a central 

 point on forehead.
