Ox/ Horse spinal processes of the anterior dorsal vertebrae of horse are shorter and stouter than Ox ribs of Ox are smoother and in the lower 2/3 are broader ox has 13 pairs of ribs - horse has 18 Ox scapular is more triangular than horse and the spine is more prominent and placed further forward (the supraspinus fossa is narrow and doesn't extend to the lower part of the bone). Instead of subsiding as in the horse, the spine rises and has a pointed projection (acromion). There is a distinct notch in the glenoid cavity of the horse, not in the Ox.  horse humorus has 3 tuberosities - lateral tuberosity is divided into 2 giving a bicipital groove). In the Ox the lateral tuberosity is very large and rises 2.5-5 cm above the level of the bone the ulna extends only half way down the radius in the horse. In the Ox it is more developed and reaches the carpus the small head of the fibula in the Ox is hook-shaped. In the horse it is separate and extends 2/3 down the tibia

 

Sheep and Goat bones of the goat are more slender than those of the sheep and the bony processes are longer and more sharply edged than in the sheep the scapula of the sheep is shorter compared to its breadth and the edge of the spine in the centre is thickened backwards, while in the goat it is straight and unthickened

Cat and Rabbit the lateral processes of the lumbar vertebrae in the cat finish in a point whereas in the rabbit there are 2 extensions - one backwards and one forward 13 pairs of rounded ribs in the cat, 12 pairs of more flattened ribs in the rabbit rabbit has long metacromium on the scapula directed backwards which is absent in the cat tibia and fibula in the cat are separate for their complete length. In the rabbit they are separate only in the upper half radius and ulna are separate in the cat but are united in the rabbit the male cat has an os penis the coccygeal vertebrae in the rabbit are very small

Fowl and Rabbit bones of the fowl tend to be whiter in colour and larger in all dimensions than the rabbit the humerus is hollow in the fowl the metatarsus is very large in the fowl and has a spur in the male the ribs are flat with uncinate processes projecting backwards in the fowl. In the rabbit the ribs are long and slender with no uncinate processes in the fowl the pelvis and sternum are very typical and not at all like those in mammals in fowl the clavicle (wish bone) and coracoid are present unlike in the rabbit the fowl scapula is not the typical triangular shape the sternal bones are fused in the fowl but not the rabbit the pygostyle is present in the fowl
