pA Be | A HISTORY OF RECENT CRUSTACEA 
duced scale in the adjoining Plate. Stenopus spinosus, 
Risso, is from the Mediterranean. 
Spongicéla, de Haan, 1849, has but one species, Sponqi- 
cola venusta, with an extensive range in the Pacific. The 
scale on the second antennz is broad, not ending in a 
point, and fringed with long plumose hairs. The third 
pair of trunk-legs have the hand large and thick and the 
preceding joit short. In the two following pairs the 
antepenultimate joint is not subdivided, and the terminal 
joint is tridentate. The telson is ovate. The species is 
said to live in the beautiful Huplectella and other similar 
sponges 
Aphdreus, Paulson, 1875, has the third trunk-legs 
long and slender; the fourth and fifth pairs with ante- 
penultimate joint undivided and finger unidentate. The 
telson is acute. Jhe third maxillipeds resemble antenne, 
each of the two slender terminal joints being subdivided 
into four jointlets. The type species is Aphareus imermis 
from the Red Sea.
