Clasp-filament narrowly snout-shaped, the spine widened 

 and appendiculate ; pile short and scanty, anteriorly situated. 

 Outer division of the lobe of the side-piece columnar, widened 

 at tip, with a short inner arm, bearing a long filament with 

 hooked tip, and a short blade-like one, arising from the base of 

 the arm; middle filament developed into a large, broadly ex- 

 panded leaf, as long as any of the filaments ; three filaments on 

 the outer aspect of apex of lobe, small and blade-like. Inner 

 division of lobe of side-piece with the arms well separated, 

 outer long and curved, inner rather long, each bearing a long 

 curved filament with expanded pointed tip. Second uncal plate 

 bifid, both limbs pointed; a curved horn from the stem near 

 the tip, the three forming a triangle. Articulated plate large, 

 oval, rounded on the margin. Basal hooks long and recurved, 

 but broadened and with spatulate tips. Basal appendages 

 large, elliptical, oblique, contiguous, with many short setae. 

 The teeth of the harpes seem to be delicate, but strong toward 

 apex. This may be due to the position of the parts in the sin- 

 gle mount.
