Among the Hyienidse, Meckel notices a separation between the 

 sacral and caudal parts of the muscle in Hi/cena striata (3-i), and 

 the same arrangement is recorded by Young (33) and, in Eyiena 

 crocuta, by Watson (37).

External muscles of thigh of Canis fwmiliaris. 



Among the Cauidae the typical arrangement exists in Canis 

 familiaris (39, 48), Canis aureus (50 a), and Canis mesomelas (51), 

 except that the ectogluteus and tensor fasciae femoris are separated 

 by a considerable interval (see fig. 1). In the Ursidce, Kelley 

 (XXIV.) states that there is no fascial insertion in Ursus maritimus 

 (55), wbile Shepherd (XX.), in Ursus americanus (59), found almost 

 the whole muscle inserted into fascia, so that further observations 

 on this point are necessary. The Procyonidse are remarkable for 

 having the ectogluteus inserted almost entirely into bone just below 

 the great trochanter ; this applies to Procyon (63, 64, 65), Nasua 

 (68, 70), and Cercoleptes (72). The same arrangement exists among 

 the Mustelidae in Mustda foina (78), Ictonyx (84), Meles taxm (86), 

 and Lutra (8S, 93).
