Fig. 201.— Convoluted Windpipe of Tantalus ibis (aftee Gaerod)., , bronchi. HERODIONES 427 are a little more complicated. The tendon of the brevis isobscurely divided into two from nearly its commencement;the more anterior of these again divides into two, one of whichruns forward to be inserted on to the fore arm separatelyfrom the hinder part, which remains continuous with the restof the tendon; there is a recurrent slip to longus. In Ahdimia the tendons are much the same; in boththese genera the propatagialis pectoralis of Ftjebeingee ismuscular. In Tantalus leucocephalus the broad fascia-like tendon ofthe brevis gives off a wristward slip, from the junction ofwhich with tendon of extenso?- matacarpi radialis a patagialfan arises. The pterylosis of the Ciconiidse has been studied byNiTZSCH. The neck is continuously feathered down toabout the middle, where the spinal and ventral tractsrespectively become divided into two.
