CLOVER. 
Anguillulid.®.* 
1, Tylenchus obtusus; 2, Aphelenchus avence; 3, Plectus granulosus , 
The natural size of above is microscopic. 
During the spring of last season many specimens were forwarded 
to me, from different localities, of diseased, and in some cases dying, 
Clover-plants, together with enquiries as to the cause of the evil. 
The plants were usually much alike in condition, that is, more or less 
decaying towards the centre, and sometimes down the main root-stem;

Plate X. of his “ Monograph on the Anguillulidce ,” published in vol. xxv. of the 
‘ Transactions of the Linnean Society.’
