Mackintosh — Notes on the Myology of the Coati-Mondi, 8fc. 53 



Extensor secundi internodii pollicis et indicis is single-headed in 

 the coatis and bicipital in the martins, the tendons in the latter uniting 

 and then diverging to be inserted (as in N. nasua) into the polles and 

 index. In N.fiisca the index tendon sends a very fine tendinous slip to 

 the middle finger ; there is also in this animal a thin palmaris brevis 

 extending over the flexor tendon of the thumb. 



The muscles of the fore foot mN.fusca are — a short abductor pollicis ; 

 an adductor from the front of the carpus ; a double abductor indicis, 

 one head arising from the carpus, and one from the metacarpus, both 

 uniting to form a single tendon ; a bicipital adductor indicis ; a single- 

 headed abductor and adductor medii ; an adductor minimi digiti arising 

 from the pear-shaped pisiform, and by a slip from the unciform ; a 

 flexor brevis ; an abductor minimi digiti, as usual; an abductor and 

 abductor annularis, also normal. The interossei are normal in JV. narica. 

 In Martes there are an abductor pollicis, extending from the radial 

 sesamoid and annular ligament to the poUex ; an abductor pollicis and 

 flexor brevis pollicis, both normal ; an abductor minimi digiti, arising 

 from the pisiform ; and an adductor minimi digiti, from the front of 

 the carpus ; a flexor brevis minimi digiti, from the unciform ; and an 

 opponens minimi digiti, which is a dismemberment of the abductor ; 

 there are besides two interossei for each digit. 



In the hind limb : — Sartorius ("08) in the coatis has a wide origin 

 from the anterior superior sjoine of the ilium as usual, and a double 

 insertion — one the ordinary tibial insertion, and the other into the 

 patella and border of the condyle of the femur ; in N. fusca the tibial 

 portion has its upper part attached to gracilis. In Martes it arises from 

 the angle of the crest of the ilium and from the inferior edge of that 

 bone, and is inserted into the patella and fascia of the upper extremity 

 of the tibia along with gracilis. 



Psoas parvus ('03) is small in iV. narica, and sends a slip to the 

 lumbo-sacral articulation ; in N. fusca it is wide and strong, with the 

 usual attachments, and in Martes it arises from the bodies of the third, 

 fourth, fifth, and sixth lumbar vertebra3, and is inserted as usual into 

 the pectineal line. Iliopsoas (*12) is normal in i\\ narica ; in N. fusca 

 it is a psoas major, with a small iliac origin ; in Martes it arises from 

 the three lower lumbar vertebrae, is inserted fleshy into the pectineal 

 line, and by a tendon into the lesser trochanter. 



Pectineus ("04) has the usual origin, and is inserted into the upper 

 half of the femur in the coatis, and into the upper fourth in the martins. 

 Adductor primus ("09) is normal and quite distinct in J^asua; in 

 Martes there is a second slip arising from the posterior half of the 

 horizontal ramus of the pubis, and inserted into the back of the femur 

 just above the condyles. Adductor secundus (+ adductor tertius -22) 

 is distinctly bilaminar in N. narica, but not in the others ; it is attached 

 as usual. Adductor tertius is separable with difficulty from adductor 

 secundus, arising in N. fusca from the spine of the pubis, and having a 

 narrow insertion into the middle point of the femur. In Martes it is a 

 small slip arising just in front of the pectineus, and behind the pecti-
