term ufed by the Greek writers . dire der what is ufually 
called unguis odoratus, or the t hoof. Some call it 
onychus indicus, aseparticularly Myreplus, in his antidote of 
ify {pecies. The fame author mentions the blatta yp haacises 
and tells us that it is not the fame thing with the o onyx 
icus, but that the Italians called by this name the os nafi 
or bone of the nofe, of the purple fifh. What he means by 
this is prebably the bony tongue of that animal, natu 
having given it fuch a weapon to pierce the thells of cake 
on which it is to feed. We frequently find the chama, 
and other fhell-fifh, with holes bored through the upper fhell ’ 
as exact as if it were done with an inftrument: this has been 
done by the purple fifh, to get at the flefh of the animal 
within for food; and the bony tongue, with which this fith 
performs this, is called, by the Italians of thofe times, blatta 
byzantia. ACtuarius tranflates the blatta byzantia of all the 
earlier writers by the phrafe os nafi purpure ; and the inter. 
ag of the Arabian writers give the fame name to what 
they call unguis odoratus, or onyx indicus, for the Arabian 
name exactly expreffes this.
