A ravins scolopaeeus has the same thin diffused tendons ; 

 but they are distinctly divided below into a main tendon and 

 a wristward slip. There is no patagial fan. 



The anconcBus has generally, if not always, a well-marked 

 broad humeral slip. 



The typical formula of the leg muscles for the cranes is 

 ABXY + . This is the case with all the members of the 

 genus Grus, excepting G. leucogeranos, where I could find 

 neither A nor B. In Aram/is and Balearica pavonina the 

 formula is BXY + , and in B. reguloruin, as in G. leucoge- 

 ranos, XY+ only. In G. americana the femoro-caudal is 

 minute and has but a feeble accessory. 



The deep flexor tendons are united by a strong vinculum. 



Both peroneals appear to be present ; but the only notes 

 at my disposal on this matter refer to G. leucogeranos. 



The left lobe of the liver is much smaller in B. pavonina, 

 a little smaller in G. ant i gone and G. virgo. The proportions 

 are reversed in Aramits. 



The gall Madder is present ; there is a good gizzard ; the 

 proventricidus is zonary. The following are intestinal mea- 

 surements : 



The intestinal coils in the crane tribe are very character- 

 istic and quite unlike those of any other birds except the 

 rails and bustards. The figure of Car-lama shows the 

 characters of the Grues generally and may be compared with 

 that of Crex on p. 323. 



The genus Grus has the most typical syrinx. In G. lenco- 

 geranos the first bronchial semi-rings are firmly attached to
