No. 4. Scirus obisium {Gerv., Ann. Sc. Nat. 1841). — 4. Magnified sketch of ditto, 

 copied from Gervais. 



This has no eyes, and would behove to have a genus for itself 

 too, if they are important as characters. As already said, they 

 do not appear to be so. 



No. 5. Scirus vestitus (Bdella vestita, ICoch).—b. Magnified sketch of ditto, copied 

 from figure in Cuvier's Regn. Anim., French illustrated edition (without 

 date), Arachnids, edited by Duges and M, Edwards.
