814 MR. K. I. POCOCK ON THE 



TAmax agrestis. 

 Sept. 24, 1910, One eaten after a good deal of pecking about 

 in the sand by White-crested Jay-Thrush. 

 Two eaten by a Shama. 

 ( >ne eaten by Kagu. 

 Tasted but rejected by Fantailed Flycatcher. 



Tasted on two occasions by Hoopoe but rejected. 



Tasted by Red-vented Bulbul but rejected. 



Tasted but rejected by Yellow Hangnest. 



Two taken, but not eaten, by Harmonious Shrike-Thrush. 



Two taken, but not eaten, by Cuban Mocking Bird. 



Limctx arborinn. 



Sept. '-!4, 1910. Four eagerly eaten by Wall Lizards, which 

 wiped their mouths to remove the sliine after swallowing them. 



Milan sowerbyi. 



Sept. 24, 1910. One taken and pecked and wiped about in the 

 sand for a long time by Indian Dial Bird, which Anally left it. 



Another specimen was eagerly taken by Sulphury Tyrant, which 

 after pecking and crunching it in his beak, and banging it from 

 side to side against a ledge, exactly as Laughing and other 

 Kingfishers do, finally swallowed it whole. 



ARACHNIDA. 



Opiliones (Long-legged Spiders or Harvestmen). 



Phalanyium sp. ? 



Sept. 1910. One (immature) tasted but immediately rejected 

 by Pekin Robin; the same specimen then taken and eaten by hen 

 Scarlet Tanager. 



One (immature) put into cage with several Curassows was tasted 

 in turn by specimens of YarrelTs and the Globose, and ultimately 

 eaten by one of the Globose Curassows, when crushed beyond all 

 recognition. 



I was led to suppose these Arachnida would prove on experiment 



to be unpalatable owing to their possessing a pair of glands, one 



on each side of the dorsal area of the carapace, which are known 



to secrete an odorous fluid. As elsewhere recorded *, I have seen 



a Mason Wasp, hunting Spiders, run down a specimen of Phal- 



angium, but turn aside and let it go unhurt the moment he 



touched it with his antenna?. More experiments with birds and 



lizards are required fully to substantiate my belief; but the refusal 



of the Pekin Robin to eat the Phalanyium is very significant, and 



it is quite evident that the Arachnid was not to the liking of the 



Curassows.
