CIRCULATORY SYSTEM 53 But the whole matter was described at considerable lengthby Gabrod, who had more abundant material to work upon,but who, nevertheless, left for his successor Forbes one outof the eight known types to describe. The most prevalenttype is that illustrated in fig. 32. It characterises a largenumber of birds. The two carotids are of equal size, andrun up the neck for the latter part of their course in thehypapophysial canal. A modification of this (fig. 33) is seenin the common bittern and other birds, where the carotidsare of equal size, but fuse into one trunk early in theircourse. In Phoenicopterus the right (fig. 34) and in Cacatua.
