Most descriptions of the circulatory system of birds, largely the workof Glenny, have dealt with arteries of the neck and thorax in a widevariety of species. As a result of his work, Glenny offered severalhypotheses concerning the phylogenetic, hence taxonomic, significance ofdifferences in some of these vessels. He also described six types ofthoracic arterial arrangements and stated that these categories mightrepresent various levels of evolution (Glenny, 1955:543-544).
The families Columbidae (pigeons) and Hirundinidae (swallows) have twonearly extre
