Philippines (exact island ?). Comparison with allied species. Cervus nigricans in its general external form, crouching Agoutilike carriage, short naked ears, flattened and wide face, more closely resembles C. alfredi than any known species. In its lighter build and uniform dark brown colour it is easily distinguished from G. alfredi, which it is spotted at all ages. From C. philippinus the new species differs in the form of the face, which in C. philippinus is laterally compressed and deep from above downwards. The length of the praemaxillae and the width across the maxillae anterior to the orbits (Plate X. b b', c c') bear a very different relative proportion to the cranial measurements in the two species. In C. philippinus the ears are of fair proportional size and externally covered with hair. The colour of the new species is much darker than that of C. philippinus. It may be useful to mention here that C. porcinus differs from all the typical Rusine deer in the possession of large inflated auditory bullae, and that C. aristoteles and its representative species C. equinus (Malacca, Borneo), G. swinhoii (Formosa), C. philippinus (Luzon), and (?) C. alfredi and C. nigricans differ from C. hippelaphus (Java) L This measurement is taken across the concavity of the ear-conch, and does not include that portion of the external ear situated inferior to the opening. 2*4 1*7 1*7 1*3 1*9 6*6 7*3 5*5 4-7 7*8 8*2 5*6 0060 0*043 0*043 0*033 0*048 0*168 0*185 0*140 0120 0*195 0*205 0140 |
