10 MAMMALIA. 



exceed one hundred in number, — but as age advances the colour 

 becomes darker, and the pale hue is entirely lost. 



The first molar is through in both jaws, and it is large ; and 

 the other two are visible behind it. No ridges have formed. 

 Extreme length of skull, occiput to front of premaxillaries, 

 I'-Ob. Presented by W. Rutledge, Esq., 1st March 1876. 



0. A young stuffed male like previous specimen : described 

 by Mr. Blyth in a footnote^ as No. 5, but not entered in his 

 Catalogue. No history. 



p. A young stuffed male like the preceding specimen, No. 4B 

 of Blyth's Catalogue. Presented by Raja Rajendra Mullick, 

 Bahadur, 1859. 



q. The flat skin and skeleton of a young male like the pre- 

 ceding specimens. Total length of the skull 6"'95 ; same age 

 of dentition as in the last individual. Presented by W. 

 Rutledge, Esq., 26th June 1S75. 



r. The skull, and skin of the head, of a young male. The 

 skin of the head has been kept on account of the great length 

 of the hair. The skull resembles the last skull, but the orbits 

 are smaller and more rounded. The first and second molars 

 are through, and the first upper incisor of the left side is 

 nearly fully displayed, while the adjoining teeth are partially 

 through. This skull in its dentition is of the same age as 

 the skull of the dark-coloured male [d) with very large front 

 upper incisors, but the total length of this skull is only 6"' 73, 

 as compared with 7"" 60 in the skull d. Its breadth also is 

 very much less, as it measures across the zygoma only 4'''50 

 to 4"'98 in d. The great differences that exist between the 

 dimensions of these skulls are also shown in the length of the 

 palate, which is 2""95 long in d, and only 'H'-bO in this skull. 

 This animal was smaller in every way than the male d, and, 

 like it, had no cheek swellings. This small Orang, however, 

 cannot well be the Mias kassir, for one of the characters of that 

 supposed species is its large incisors and molars, a distinctive 

 feature of the larger of these two Orangs, viz., of No. 3 d, 

 and it is not probable that three species of Orang exist. I am, 

 therefore, disposed to regard these differences only as individual, 

 and there can be no doubt that they are very great, but not 

 greater than the differences in dimensions of skull, and in the 

 size of teeth, that exist among individuals of the various races 

 of men. The next skull reveals also even greater differences 

 of dimensions than in the case under consideration. Pre- 

 sented by W. Rutledge, Esq., 1st June 1880.
