302 Mr. F. E. Beddard on the Anatomy 



being empty of viscera, save for a portion of the gizzard, 

 which projected into it. Of the two vertical membranes that 

 on the left seemed to me to be the real equivalent of the 

 falciform ligament of other birds ; for it was attached to 

 the sternum in the middle line and to the gizzard approxi- 

 mately so ; moreover, it carried blood-vessels. The right 

 hepatic recess has thus its own median wall, while that of 

 the left hepatic recess is formed by the falciform ligament. 



1 have used the expression " median " as indicating the 

 position of that septum with regard to the two hepatic 

 chambers. As a matter of fact, the septum in question is 

 rather oblique in its direction, trending distinctly toAvards 

 the right side of the body. It has been, I imagine, pushed 

 backwards by the growth of the liver-lobe, and really corre- 

 sponds to the transverse partition which shuts off the same 

 liver-lobe in Scythrops* . 



c. Alimentary Canal. 

 The intestines are, as in the Cuckoos generally, short. The 

 small intestines measure 24 inches ; the large intestines only 



2 inches, or a trifle more ; the caeca 3 inches. It has already 

 been mentioned that the right lobe of the liver is the larger. 

 The gall-bladder is very large, and its duct, the hepatic duct, 

 and the pancreatic duct open into the small intestine at the 

 top of the U in the order mentioned, the first-named duct 

 being furthest away from the pylorus. 



The proportion of the length of the cseca to the length of 

 the intestines does not differ widely from what is seen in 

 other genera, saving only Scythrops, which appears to have 

 abnormally long caeca f. 



d. The Windpipe. 



The syrinx of Carpococcyx (figs. 20, 21, p. 203) is the most 



purely bronchial syrinx that exists among the Cuculidae ; it is 



even more exaggerated than that of Crotophaya. To the 



syrinx of the latter genus that of Carpococcyx bears the closest
