oval, pointed delicate ribbed leaf arising from an insertion 

 about the middle of the shaft rather on the inner side ; an inner 

 slender arm, which bears a long and a short filament at tip ; 

 middle filament between these and the outer group of three 

 flattened and bent filaments, which arise close together. Sec- 

 ond uncal plate furcate, one limb horn-like. First plate broadly 

 triangular. Basal hooks long. Basal appendages large, ovate, 

 contiguous, with many setae. Inner division of lobe of side- 

 piece with two arms, the inner short.
