(330 CYNOl'TKKUS IloKsKIELDI. 



Tiipe, skin and skull of an adult male, U.S. National Museum, 

 no. 141236. 



Rcmarls. — This species appears to be a Nias representative of 

 C. hmchyotis amjulattis (Assam to Sumatra), from wbicb it differs 

 only by its markedly larger size ; but the difference in this respect 

 is sufficiently well marked to allow major to stand as a distinct 

 si)ccie8. The large size of G. major might easily suggest the idea 

 that it is more closely allied to C sphinx tittha'cheilus, but the size 

 is in reality the only character in which it approaches titthacheilus; 

 the ears are perfectly similar to those of hrachyotis, not nearly as 

 large as in all known forms of the spliinx type.

(Synonyms under the subspecies.) 



Differential characters.— A. well-developed surface cusp always 

 present in p^ and m^ ; cheek-teeth broad, subrcctangular in outline; 

 forearm G4-5-77"o mm. 



Premolars and molars broader than in the foregoing species, a 

 cliaracter conspicuous in all cheek-teeth, though more so in p\ p', 

 p,, and Pj than in m' and m, ; p', p^, and m^ quite or nearly as 

 broad anteriorly and posterioily as at middle, outline of these teeth 

 therefore subrcctangular or subsquarish, not oval (^ee fig. 49, p. 589, 

 dentition of C. princeps). Surface elevation of p^ and m^ usually 

 conical, sometimes taking the shape of a short sharply defined 

 longitudinal ridge. Cranial rostrum short, deep, and broad, less 

 than one-fourth of total length of skull (as short as, or rather still 

 a little shorter than, in the shortest-nosed of the foregoing forms). 

 As conse(iuences of the heavier dentition, zygomatic arches un- 

 usually flaring, coronoid process somewhat broader and more 

 steeply ascending, angular process more prominent. External 

 characters not peculiar (for an average difference in the colour of 

 adult males see below). 



Colour. — As in average specimens of C. h. hrachyotis, but adult 

 males usually distinguisbable by the more saturated colour of the 

 sides of the neck, foreneck, and sides of the breast. 



Adult male8(C'. /;. horsfieldi, four skins, November and Decemher): 

 Back brown lightened with russet or cinnamon or a tinge between 

 li nnamon and wood-brown ; head darker, more uniform olive. Breast 

 and belly paler or darker drab or broccoli-brown, usually with a deli- 

 cate touch of light tawny-olive or Isabella. Sides of neck, foreneck, 

 and sides of breast deep hazel or cinnamon-rufous, inclining to 

 burnt sienna or chestnut, contrasting with colour of breast and 

 belly. Ears broadly margined with white ; metacarpals and pha- 

 langes brownish white. 



Adult females (f. h. horsfiehli, four skins, November, December, 

 January) : Uiflering from males chiefly in the much paler colour of 

 the sides of the neck, foreneck. and sides of breast. Back varying
