From this list it would appear that in the Felidae and Ursidae 

 the costal attachment is most extensive, while in the Mustelidse it 

 is least so. 



Deltoid. — This muscle consists of the usual three parts — clavi- 

 cular, acromial, and spinous. The former blends with the ventral 

 portion of the trapezius to form the cephalo-humeral or levator 

 humeri, and is inserted into the lower half of the humerus or the 

 bones of the forearm. 



In the Felidse the insertion seems to be into the forearm, at least 

 this is the case in F. leo (1 a, 2) and F. catus (6). Among the 

 Viverridse the insertion is also into the forearm in Cry]3toprocta 

 (10), V. civetta (13), Geneita (17, 18), and Herpestes (24), In 

 Young's specimen of V. civetta (VIII.) the muscle was inserted 

 into the lower end of the humerus. In Proteles (25) the insertion 

 is also into the forearm. Among the Hyaenidse the muscle is 

 inserted into the humerus in H. striata (26) and H. hrunnea (30), 

 into the forearm in H. striata (28), Among the Canidae it goes to 

 the humerus in Canis familiaris (31), to the forearm in Lycaon 

 joictiis (44). In the Ursidae its insertion is into the humerus in 

 U. maritimus (45) and U. americanus (49, 52), Among the 

 Procyonidae it goes to the humerus in P. lotor (53, 54) and C'erco- 

 leptes (61), In the Mustelidse it is also usually inserted into the 

 humerus ; this is the case in Galictis harhara (64), Mustela puiorius 

 (65), M. foina (67), Ictonyx zorilla (69), Lutra vulgaris (74, 79), 

 and Lutra cinerea (78). In Tctonyx lyhica (70) the insertion is 

 into the lower end of the humerus as well as into the forearm 

 bones. 



From this it will be seen that in the Felidse and Viverridae the 

 normal insertion of the first part of the deltoid or cephalo-humeral 

 is into thp forearm. In the Ursidae, Procyonidae, and Mustelidae it 

 is into the lower end of the humerus, "while in the Canidae and 

 Hyaenidae it may go into either. The acromial and spinous parts 

 of the deltoid are inserted into the middle of the humerus, the 

 acromial lowest, the spinous just above and deep to it.
