Ser7-atus magnus arises from the transverse processes of the five 

 posterior cervical and first dorsal vertebrse, and by seven costal slips 

 from the eight anterior ribs, excluding the first. It is inserted into 

 the vertebral border and part of the ventral surface of the scapula. 

 The muscle is similarly arranged in H. striata. In the Civet the 

 cervical part is limited to four vertebrae ; and in the Dog the costal 

 attachment is less by one digitatiou. 



The intercostal series of muscles are normal. 



Triangularis sterni strong and well marked. It takes origin 

 from all the pieces of the sternum except the first, and passes 

 to the cartilages of the second to the sixth ribs inclusive. A sepa- 

 rate muscular band arises from the side of the eighth sternal segment, 

 and runs transversely to the posterior margin of the seventh costal 

 cartilage ; though distinct from the triangularis and interposed be- 

 tween it and the intercostal muscles, it can only be regarded as an 

 aberrant slip of that muscle. 



The diaphragm has the ordinary attachments. It possesses no 

 special aperture for the passage of the vena cava, that vessel passing 

 with the aorta behind the crura. 



Of the abdominal muscles the external oblique is from the last 

 eleven ribs to its usual insertion. The internal oblique is easily 

 separable from the transversalis. 



Rectus abdominis, from the posterior extremity of the symphysis 

 pubes, is inserted into the seven anterior costal cartilages, close to the 

 sternum. The prolongation of the rectus to the first rib is usual in 

 Carnivores. As mH. brunnea, there is no pyramidalis ; this muscle 

 is also absent in H. striata. There is but a single supracostalis ; 

 it extends from the cartilage of first rib to the aponeurotic insertion 

 of the rectus opposite the third and fourth costal cartilages. Two 

 such muscles are noted in H. brunnea, whilst the Dog agrees with H. 

 crocuta in possessing only one (" musculus in summo thorace situs " 

 of Douglas). 



Coccygeus is attached to the roots of the transverse processes of the 

 first three coccygeal vertebrae and to the ischial spine. 



The remaining muscles of the region, i. e. those in relation to tlie 

 generative organs and rectum, are described in a previous communi- 

 cation. 



The tail is supplied with a levator caudce, which arises from 

 articular processes of the last three lumbar vertebrae, and is reinforced 

 by muscular slips from the laminae of the caudal veitebrae, into the 

 spines of which it is inserted by means of delicate tendons. 



The depressor cauda, from the bodies of sacral and coccygeal 

 vertebras, receives also a special muscular slip from the pelvic aspect 

 of the ilium. Its insertion is by narrow tendons into the bodies of 

 the caudal vertebrae. 



Laterules caudce are constituted by the intertransversales of the 

 caudal region. 



Muscles of the Fore Limbs.
