patch at the larger end, leaving the rest of the shell com- 
paratively free. Those in my collection vary from 20 to

bird varies from 5 inches to 5:5, measured in the flesh. Iris 
umber-brown, legs pinkish grey; the iris of the immature 
bird is darker, being hardly distinguishable from the pupil, 
and the legs are white, tinged with purple on the toes.
