POISONOUS BITE OF CONUS 



CHAP. 



and the native explained that had he not taken these precautions 

 he would have died. Instances have been re- 

 corded of poisonous wounds being inflicted by the 

 bite of Conus aulicus^ C. textile^ and C. tidipa. 

 According to Mr. J. Macgillivray ^ C. textile at 

 Aneitum (S. Pacific) is called intrag^ and the 

 natives say it spits the poison upon them from 

 several inches off I Two cases of bites from O. 

 textile occurred to this gentleman's notice, one of 

 which terminated fatally by gangrene. Sir Ed- 

 ward Belcher, when in command of the Saynarang^ 

 was bitten ^ by a Conus aulicus at a little island 

 off Ternate in the Moluccas. As he took the 

 creature out of the water, it suddenly exserted its

 living C. textile. Before he could pick it up, one of the natives 

 hastily snatched it away, and explained, with vivid gesticula- 

 tions, its hurtful qualities. On no account would he permit 

 Mr. Hedley to touch it, but insisted on himself placing it in the 

 bottle of spirits. 



Mimicry and Protective Coloration. 



Cases of Mimicry, or protective resemblance, when a species 

 otherwise defenceless adopts the outward appearance of a better 

 protected species, are rare among the Mollusca. Karl Semj)er* 

 mentions an interesting case of the mimicry of Helicarion tigri- 

 nus by Xesta Cumingii, in the Philippines. It appears that all
