SUMMARY OF THE IXDIAN MAMMAL SURVEY. o53 



There is little doubt that the real name for this genus is Simia, 



biit that name has been used for alorg- period 

 Gen. 1, -Macai'A. of years for the Orang Utan, and it is now 



proposed to except it, by " liat, " from the 

 strict rule ot priority (Thomas. A. M. M. 11. (b), xvii, p. 170, 

 191(5). Pending the final settlement of this matter it seems most 

 convenient to use the next oldest name. Blanford accepted 

 Lacepode's name Macact'S (1801) but two years earlier the latter 

 had used Macaca (Tabl. Mamm. 4, 1799;.' 



Considerable misunderstanding seems to have arisen as to these 



two species owing to the loss of the 

 No. 3. rhesus, Kwdi. •'•' type of «ssamfe//M".s, and the absence 

 No. 4. ossamensxs, 'McCl. of topotypes. Stud}- of the Survey 



specimens leads me to the conclu- 

 sion that the assamensis of Blanford represents the macaques of the 

 Chindwin and Shan States, and that pelops, Hodgson, is a distinct 

 species (J. B. N. H. S., XXIV., p. 476, 191G). It seems to me 

 impossible to lump these three species under one heading, viz. : — 

 " Colour brown," as in Blanford's key, under A. b. 



True (Proc. U. S. N. M., xvii, p. 2, 1894) has given the name of 



villosus to the Kashmir form of rhesus. (A specimen collected by 



Capt. F. D. Sterling at Kaotai, 3,600', Lower Chitral, sent to the B. 



^I. for identification by the B. N. H. S., would seem to be this form.) 



Blanford notes that neither silenus nor veter are applicable as 



names for this monkey, consequently 

 No. 5. silenus, Schreb. thename /eyoa?, Shaw (Mus. Lev., p. 69, 



1792) must be used for it. 

 The name nemestrinus, L., was based on the form from Sumatra. 



Miller established adusfa, (Proc. 

 No. 6. arctoidjis, Geoff. U.S. N. Mus. xxix., p. 559. 1906) 



No. 7. leo'ninus, Bl. for the continental form, marked by 



No. 8. nemestrinus, L. the almost complete absence of the 



No. 9. cynomolgics, Sshreb. dorsal black stripe and by the black 

 No. 10. sinicus, L. annulations present in the hairs of 



No. 11. pilaetus, Shaw. the back (J. B. N. H. S., xxiii, 



p. 700,1915). Blanford admitted- 

 ly uses the name cijnomohjiis wrongly (Mamm., p. 23.) Bonhote 

 pointed out (Fasc. Mai. I, p. 4, 1903), that the oldest name for the 

 Malay macaque is fcucicularis, llaff. AVitli these alterations the 

 marginal list stands. 



1 propose to substitute for Blanford's the following modified key, 

 viz. : — 



Key to the species o/Macaca. 



A. — Tail less than three-fourths of head and 

 body together.
