 and h.w. un.s. v. marked, and 2 wh.-pupilled apical eyes un.s. f.w. with often a 

 3rd unpupilled : those from the Rochers de Naye have far less conspicuous bands 

 un.s., and are often without apical eye-spots, or only one, up. and un.s.; the 

 bands and eye-spots of ? s are, however, v. distinct.]
