Genus Tetraclita Schumacher. 
Tetraclita squamosa (Bruguiére) Schumacher. 
(= Tetraclisa porosa (Gmelin) Darwin.)

Pilsbry (1916) names this form „subsp. sgwaraosa (Bruguiére)“; 
although the nomenclatory rules are not quite clear on this point, 
it cannot in this case any more than in other cases be in accord- 
ance with their meaning that the same name can be used without 
special suffixes for different systematic categories; it is, therefore, 
misleading to use Bruguiére’s name for the subspecies as long 
as it is also used for the species, and I here prefer to maintain 
the variety-name viridis of Darwin which is used for the main 
form in all other papers on cirripeds. 
Forma rubescens Darwin. 
La Jolla, Calif.; on the Coastal rocks. 21/VIII 15. Two great specimens
