LOGGBR-HEAD SHRIKE. 437 



few may be found through the winter ; but the number is ten times 

 greater in summer ; and such is also the case with the Mocking Bird. 

 It appears fond of the little changeable Green Lizard (Anolius Caro- 

 linensis, Cuv.), and I have seen exertions of skill and activity on the 

 one part in seizing, and on the other in avoiding their enemy, but the 

 reptile, in spite of all its agility, is frequently secured. On one occa- 

 sion I had marked a lizard of this species on a fence. It was then beauti- 

 fully green ; but on being chased by a Shrike, which observing me flew 

 off, I found that it had become quite brown. 



" This species breeds twice in a season, lays four and sometimes five 

 white eggs. Occasionally it feeds on the small black berries of a species 

 of Smilax ; this is in winter, when it is probably pinched for food. I 

 have noticed it building its nest in the same tree for a succession of 

 years, never repairing an old nest but always building a new one." 



According to Mr Swainson this species is found on the Table Land 

 of Mexico, where it is very common. 



A male preserved in sprits measures 8i§ inches in length; extent 

 of wings 12 ; wing from flexure 4 ; tail 4^. 



The roof of the mouth is as in the other species ; its width 7 twelfths ; 

 the tongue is 6 twelfths, the posterior aperture of the nares 5 twelfths. 

 The lobes of the liver are very unequal, the right being the largest. 

 The oesophagus is 2\ inches long, 4 twelfths in width, but on entering 

 the thorax contracting to 2i twelfths ; the proventriculus 3 twelfths. 

 The stomach is irregularly elliptical, a little compressed ; the muscles 

 thin, especially the lower ; the epithelium thin, tough, brownish-red, 

 with longitudinal rugae. The intestine is 9 inches long, from 3 twelfths 

 to 1 twelfth wide; the coeca extremely small, 2^ twelfths long, ^ twelfth 

 wide ; the cloaca small and oblong. 



The trachea is 2^ inches long, moderately flattened. If twelfth 

 broad at the commencement, 1 twelfth at the lower part ; the rings 

 firm, about 56, with 2 dimidiate rings. The lateral miiscles are very 

 slender, as are the sterno-tracheal, and there are four pairs of inferior 

 laryngeal muscles on each side, forming a large pad, as in the Thrushes. 

 In this respect the Shrikes resemble the Turdinw and Byhiance^ much 

 more than the Flycatchers, of which the inferior laryngeal muscles are 

 small and blended. The bronchi are moderate, of about 12 half rings.
