 llisso, is from the Mediterranean. 



Spo7igicola, &e Haan, 1849, has but one species, Spongi- 

 cola venusta, with an extensive range in the Pacific. The 

 scale on the second antennae 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 joint short. Tn 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 Eupledella and other similar 

 sponges 



Apliarevs, 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. The third maxillipeds resemble antennas, 

 each of the two slender terminal joints being subdivided 

 into four jointlets. The type species is Aphareus inermis 

 from the Red Sea.
