The genera Dindymene Typhloniscus and Carmon the author places with some hesi- 
tation in Group 1, which may be regarded as reversionary or degenerate types on ac- 
count of their primitive adult cephalic features, combined with morphological char- 
acters. 
The genera Salteria, Avalonia, Bathynotus, Telephus and Cyphoniscus may be ulti- 
mately found to possess eyes.
