The gross morphological study on the scapula of Indian Wild cat revealed that it was flat and quadrangular bone with two surfaces, four borders and four angles. The scapular spine was well developed with increasing height distally and its termination in the acromian process. The acromian process was divided in to hamate and suprahamate process which were triangular and in the form of quadrilateral plate, respectively. The ratio of supra and infraspinous fossae was approximately 1:1. The subscapular fossa presented four ridges and the nutrient foramen was present near the scapular neck. The scapular notch was formed by the continuation of ventral border and it was extended up to supra-glenoid tubercle. The coracoid process was well developed and hook like. The glenoid cavity was shallow and oval with laterally placed glenoid notch. K e y w o r d sHamate and Suprahamate process, Scapula, Subscapular fossa, Supra and infraspinous fossae, Wild cat

The present investigation was performed on four humeri of adult Indian wildcat to observe its characteristic features. It was a long and slender bone with a well-developed shaft and two extremities. The shaft was prismatic in its upper third, cylindrical in the middle third and compressed anteroposteriorly in its remaining part. The lateral surface was marked with the crest of humerus, anteriorly and the tricipital line, posteriorly. The medial surface was wide and located below the intertubercular groove and it had nutrient foramen in the distal one third. The posterior surface was present only in distal 1/3rd of bone and was triangular. The proximal extremity composed of head, neck, lesser tubercle (medial tuberosity), greater tubercle (lateral tuberosity) and intertubercular groove (bicipital groove). The distal extremity was composed of two condyles, epicondyles, supracondylar foramen and olecranon fossa. The supracondylar foramen was present medially and elongated oval in shape.

Histologically, the papillary muscles of the heart of buffalo consisted of three layers; endothelium, subendothelial and myocardial layers from within outwards. Endothelium was a simple squamous epithelium, which was supported by a subendothelial layer which consisted of loose connective tissue mainly collagen, elastic fibers and adipose tissue. The endothelial and subendothelial layers together form an endocardium. The central layer, considered the normal myocardial layer, consisted of cardiac muscle. The muscle fibers appeared long, striated, branched and anastomosed; some binucleated cells were occasionally observed, with centrally placed nuclei having prominent nucleoli. The sarcoplasm of cardiac muscle was eosinophilic, full of parallel contractile myofibrils that consisted of myofilaments with a very strong cross striated banding pattern. The purkinje fibers were organized into bundles at the subendocardial region and in between and surrounding the cardiac muscle bundles. Chordae tendinae also consisted of three layers; outer endothelial, middle subendothelial and central fibrous layer.
