Skull belonging to the low, flattish type characteristic of Nepalese Serows, 

 owing to the transverse and longitudinal flatness of the frontal bones above the 

 orbits. The following are some of its dimensions in millimetres (25 mm. = 

 1 inch) as compared with those of a skull from Nepal : — 



The horns measure 185 mm. (= 7| inches) in length and 120 mm. (:= 4j 

 inches) in basal circumference. 



These measurements show certain differences between the two skulls, but only 

 such as are I think attributable to individual variation or to age. Thus the 

 greater length of the cheek-teeth in the Chumbi specimen which is smaller in 

 almost all respects than the Nepal example is I believe a matter of age. Again 

 it will be noticed that although the posterior width of the palate is greater in 

 the smaller skull, the width of the last molar is correspondingly less, so that 

 the measurement taken to include the molars is almost the same in the two, 

 the truth I think being that the molar increases in width up to a certain point 

 of course with age and the palate correspondingly decreases in width. The 

 flatness of the skull above alluded to is well shown by the measurements taken 

 from the alveoli of m^ and pm" to the summit of the frontals and nasals in a 

 vertical line above them. If these be compared with similar measurements 

 yielded by a skull of Rodon's Serow from Chamba in the Punjab and of the 

 Kashmir Serow from Pir Punjab (see my paper, P. Z. S., 1908, p. 189) the value 

 of the difference will be appreciated.
