 lobes short, twice as broad as long, distal margin with five 

 tooth-like projections; second pair of lobes similar to me- 

 dian, shorter; third pair of lobes short, smaller than sec- 

 ond pair, irregular; pectinae arranged 0, 2, 2, 1, broad dista- 

 pectinae; incisurae with six altaceratuba-like oraceratubae.
