110 ME. G. BUSK ON THE ANCIENT OR 



thoroughly fossilized. A second sacrum, of rather smaller size, but in the same con- 

 dition, was found about two feet lower. 



Of other parts of the pelvis all I have been able to make out are — portions of the 

 right and left ischia, forming parts of the same skeleton, and a portion of the right 

 OS innominatum with the acetabulum complete. The diameter of the acetabulum 

 (slightly worn down) is 1""6. 



4. Scapula. 



Of this bone there are about eight specimens, all of which, except one, are broken 

 so much in the same manner that it seems highly probable that they represent the 

 remains left by a Dog or Fox. 



The remaining portion in every case includes the glenoid cavity, sometimes with and 

 sometimes without the coracoid tuberosity. In two instances (one of which is figured 

 in PI. XXI. fig. 5) a portion of the spine is left ; but in most that process is broken off 

 entirely. The size of the glenoid cavity varies in its longest diameter from l"-6 to l"-4. 

 But the radius of the curve of the hollow only varies from l"-0 to 0"-9, so that even 

 the smaller might have sufficed for the reception of a head of the humerus not so 

 much less than the others as might be supposed. 



In a specimen of C. elaphus (689 a, B.M.) the longest diameter of the glenoid fossa 

 is l"-5, and in C. barharus (No. 1043 a) l"-4 ; so that the Gibraltar specimens are 

 so far clearly within the limits of the same species. 



5. Humerus. 



The specimens of this bone, all fragmentary, are about six or seven in number. The 

 antero-posterior diameter of the head is in two cases about 2"-7, whilst the distal 

 articular extremity measures about 2"-0 X 2"-2. The least circumference of the shaft is 

 in one case 3"'9, and in another 3"'4. 



In Cervus elaphus (689 ra, B.M.) the antero-posterior diameter of the head is 2"- 9, and 

 the distal end measures 2"-0xl""9, and the least circumference of the shaft 3"-2. 



In the specimen of C. barbarus (1043 a, B.M.) the length of the head is 2"-8, the size 

 of the distal extremity 1""7 X 1"'7, and the circumference of the shaft 3"'0. 



6. Radius. 



An entire radius, which exactly fits one of the humeri, is represented in PI. XXI. 

 fig. 3. It measures 10"-2 in length, the proximal end 2"-0xl"'0, and the distal l"-3x 

 l"-6 ; the least circumference of the shaft is 3"'0, and the perimetral index -284. 



A second specimen consists of only the proximal portion, 4"'0 long, of the left radius. 

 The proximal articular end measures l"-lx2"-l. The bone is sun-cracked, very dense 

 and heavy, and it also fits to one of the humeri. 



In the specimen of C. elaphus taken for comparison (above cited) the radius measures
