 structure ^-ithin very definite circular boundaries, at one side 

 embedded in a mass of indistinct fibrillae ; 4th and 6th organs 

 seemingly of same general type as 2nd and 8th, but somewhat 

 larger, the 4th being strongly displaced inwardly ; central 

 organ resembling the 3rd and 7th, being considerablj'' larger 

 than these, though smaller than the terminal organs.
