78 DISEASE IN WILD MAMMALS AND BIRDS 
favorite site of deposit. Like the parrots their arterial 
damage is not confined to the aorta, but may be found in 
the carotids, femorals or small wing arteries. The most 
common situation is, however, in the lower thoracic and 
renal regions. 
Galli, represented by five specimens, seem to have 
their vascular disease accompanied very often by myo- 
cardial and infectious disease. Their arterial pathology 
consists of raised gray patches in the aorta only. 
Steganopodes give the highest percentage among 
avian orders, but this must be held sub judice because of 
the small number of specimens subjected to autopsy. 
Renal disease occurred in three cases. Their lesions are 
in the form of yellow opaque streakings in the aorta and 
its branches, in one case following the carotid half way up 
the neck. Plaques are not common, and when they occur 
are streaky and illy outlined. 
Herodiones, represented only by a heron, are neg- 
ligible. This bird showed a diffuse thickening with early 
thrombotic deposits attached to the intima. 
Palamedes are represented by a Screamer which 
showed around the orifices of the renal arteries an early 
fatty deposit and mesial opacity. 
Anseres present a considerable number of cases which 
are accompanied by cardiac, renal and general pathology. 
The character of the lesions is like that of the Accipitres 
and the distribution differs in only one particular. In 
four of these eleven cases the elevations or opaque areas 
were limited entirely to the stretch of aorta which might 
be compared to the arch in mammaUa, that is the part 
with which the right subclavian is in closest contact and 
which bends almost directly backward to become the 
thoracic aorta. This excludes the ampulla just above 
the aortic valves. There seems no real reason for this 
and it may be accidental. 
Struthiones, with seven specimens having arterial 
disease in the great vessels alone, seem to have no
