corresponding to the right aortic arch is present ; but its presence is 
found in so many Accipitres that it is highly characteristic of them. 
I quote from MS. of Garrod the following measurements of the 
various parts of the alimentary tract to show how close is the 
resemblance between the two :— 
Cariama. Chunga.

The expansor secundariorum is as in Chauna and Cariama. 
There is no biceps slip to patagial tendon as in Cariama. The 
anconeus has an accessory flat tendon attaching it to humerus. 
The pectoral muscle arises from the whole of the sternum, which 
is free from the origin of the second pectoral; it also arises from 
the aponeurosis of the second pectoral. It is partially divided by a 
septum into two muscles. 
The tensores patagii brevis and longus appear to form one muscle 
at their origin ; this muscle receives a tendon from deltoid ridge of 
humerus. The tendon of drevis is very large and flattened out, but 
as it is accurately figured by Fiirbringer’ I do not describe it more 
fully. A drawing of Prof. Garrod’s shows that in Cariama the 
tensor brevis tendon is similar, and he particularly states that there is 
no biceps slip ; neither Fiirbringer nor myself have found a biceps 
slip in Chunga. 
The accessory femoro-caudal is present in Curiama, and it is stated 
by Garrod in a MS. note to be missing in Chunga; however, I 
found this muscle in the specimen dissected by me; it was thin and 
slender, and became tendinous in the middle between its origin and 
Insertion, 
The biceps brachii in Chunga is bifid at its insertion.
