Test of adult female conical or limpet-shaped, white, glassy, 

 slightly elongated, striated with rows of air-cells radiating from 

 the apex, and increasing in size to the edge. Length of test,

 joints some hairs. Feet normal; upper digitules very long, 

 lower pair narrow. On the edge of the body is a row of spines, 

 of which each alternate one is conical, the remainder club-

 row of spinnerets, beyond which is a narrow line of short regu- 

 lar curves. Abdominal cleft wide and circular above, the ex- 

 tremities almost meeting. Anal ring with eight long hairs.
