STRUCTURE AND CLASSIFICATION OF BIRDS 



described by ScLATEE. 1 There are two patches in the 

 lumbar region, lying between the dorsal and the femoral 

 tracts. 



The tongue of the rollers wants the spiny fringe at the 

 base which is so common a feature of this organ in other birds ; 

 it is horny in front and entire at the tip. The liver has a 

 larger right lobe and a gall bladder. 



The following are intestinal measurements:- 



The tensores patagii of Leptosomus are figured in the 

 accompanying cut. 2 The brevis tendon gives off a wrist- 



ward slip just before its attach- 

 ment to the tendon of extensor 

 metacarpi radialis longus, over 

 which it passes to be inserted 

 below. There is no biceps slip. 

 Coracias gar ml us is the 

 same save for the fact that 

 there are two separate brevis 

 tendons, from the first of which 

 the anterior gives off the 

 wristward slip ; the inner 

 thinner tendon of these does not 

 cross the wrist. Eurystomus 



does not differ. In these birds
