(This form has a trypa, but it is covered over by the avicularian cell ; by the kindness ol 

 Mr. Kirkpatrick I have been enabled to dissect off an avicularium, and thus demonstrate 

 the presence of a trypa. The form is probably entitled to specific distinction, and I there- 

 fore record it as Adeonellopsis imperforata.)
