lu the yiiidae (4, 7, 11, 12, 14) the medius alone is present, 

 lu our specimen of the Pig (11) the nerve passed entirely above 

 the mnsi-Je ; but in the Peccaiy a small part of the muscle was 

 above the nerve. 



Bronn says, apparently on the authority of Bendz, that the 

 brevis and medius are present ; but from our experience we are 

 entirely unable to agree with this. In the Camel (18) Meckel 

 says that the muscle is inserted into the upper half of the humerus, 

 but whether the brevis is present or not we have no knowledge. 



In our Chevrotain (21) only the middle part was present ; but 

 Kinberg describes internal, middle, and external ])ortious in his 

 (20) ; as these all seem to be inserted below the upper third of 

 the humerus, and none of them reach the lower extremity of the 

 bone, wo presume that they are component parts of the medius, 

 and it is possible that one of the separations was formed by the 

 nerve. 



In the Cervidte (2o, 27, 28) and Bovida> (33, 36, 38, 44, 48, 

 45, 49) we believe that the medius or medius and longus are the 

 only parts present, and that the medius is always pierced by the 

 nev\e to the biceps. Bronn says that in the Ox and Sheep the 

 longns and brevis are present ; but apparently this generalization 

 is taken from other authors, and no details of the exact attach- 

 ments or the relations to the latissimus dorsi or nerve are given. 



In the Giraffe, Murie (XXXII.) and Joly and Lavocat (XII.) 

 describe a brevis and longus, but exact details are wanting. 



In the Tapir (50, d2, 54, 55) our specimen agrees with the 

 descriptions of three other observers, that the insertion is into the 

 lower three quarters of the humerus, that is to say that the 

 medius and longus are present. 



In the Horse, Bronn (VI.), Chauveau (II.), Lesbres (V.), and 

 Meckel (VII.) describe a brevis and medius between which the 

 musculo-cutaneous nerve passes, and in Cuvier and Laurillard's 

 plate these two parts are clearly shown in the Ass (I.). 



In the Ehinoceros (64), Haughton (XXI.) describes a medius 

 inserted into the middle of the shaft of the humerus for three 

 inches ; but in Beddard and Treves's animal (63) the longus was 

 alone present and was inserted just above the internal condyle. 



In the Hyrax (67, 68) the medius alone was found (see text- 

 fig. 91), but iu (71) there seems to have been a longus as well. 



In the Elephant (72, 74, 76, 77, 78, 79) the insertion extends 

 from the level of the attachment of the latissimus dorsi to the 

 internal condyle, so that, although the position of the nerve is not 

 given, it is pretty evident that in this animal the medius and 

 longus ave the two parts normally found. 



BracMaJis nnticus {flexor brevis cubiti).—In Ungulates only the 

 outer head of this muscle is present: it rises from the back of 

 the surgical neck of the humerus, winds spirally round that bone, 

 and is inserted into one or both bones of the forearm a little below 

 the iusprtion of the biceps. In all the animals in which we care- 

 fully examined the insertion— Pig (11), Peccary (14), Brocket (27),
