3779. The skeleton of the Nahura Argali (Ovis Nahura}. 



The vertebral formula is : 7 cervical, 13 dorsal, 6 lumbar, 4 sacral, and 10 caudal. The 

 ast rib is articulated by the head only. The metapophyses commence on the sixth dorsal, 

 and gain the outside of the zygapophyses in the twelfth, retaining the same position, with 

 the form of tuberosities throughout the lumbar series. The lacrymal joins the nasal, but is 

 not impressed by a lacrymal pit. The premaxillary joins the nasal. The base of the horn- 

 core is subquadrate, with the angles rounded : the horn is directed upwards and outwards, 

 with a slightly spiral twist backwards : the corneous sheath is traversed, above, by a longitu- 

 . dinal ridge, which is not indicated by the bone-core : it is feebly annulated. The cranial 

 characters cf the Nahura are intermediate between those of the Capra Hircus and Ovis Aries. 

 The medullary artery enters the fore and upper part of the femur. 

 From Thibet. 



Presented by Captain Strachey, R.E. 



The following, to No. 3807 inclusive, are parts of the same skeleton of the Aoudad or 

 African Argali (Ovis tragelaphus). 



Purchased. 



3780. The cranium, vertically and longitudinally bisected. 



The right horn had been broken off during the animal's life-time, and the base of the horn- 

 core, which was covered by a callous dermal cicatrix, is widely open, showing the communi- 

 cation of its cavity with the frontal sinuses. The left moiety shows the complete septum 

 which divides the extensive frontal sinuses of one side from those of the other. The base of 

 the horn is trihedral, with the longitudinal diameter transverse to the axis of the skull : 

 the frontal is flat, and ascends from the nasal straight to the base of the horns, which curve 

 obliquely backwards, outwards and downwards, with the apex slightly twisted inwards. The 

 number of the anuulatious of the horn indicate them to be developed at shorter periods than 

 years. The long nasal bones are continued forwards in almost the same straight line with the 

 frontals. The facial plate of the lacrymal is very long : it articulates with the nasal, leaving 

 a small interval between it, the base of the nasal and the frontal : its external surface is slightly 

 depressed. The premaxillary does not reach the nasal. The numbers on the individual bones 

 in the left moiety indicate their names according to the TABLE OF SYNONYMS. 



3781. The two rami of the lower jaw. 



The permanent dentition is shown in both upper and lower jaws. 



3782. The atlas. 3783. The axis. 



3784. The five other cervical vertebrae. 3785. The twelve dorsal vertebrae.
