nd the complicated gills and gill-fan (scaphognathite) correspond 

 \ the gill and flabellum of the Phyllopodous leg or flabellum. 

 In brief, the maxillae of the Decapoda most closely resemble 





epipodite or flabellum, or scaptogath- 



the legs of Phyllopods. The maxillipedes, for example, those of 

 the third pair, are much more differentiated than the limbs of the 

 Phyllocarida or Phyllopoda. In the Decapoda the gill and flabel- 

 lum are homologous with those of the groups just enumerated; 

 while the endopodite and exopodite of the Decapoda represent 



extr emity of exopodite or palpus ; flab, epipodite. 



e endopodal portion of the limb of the lower groups. There 

 in the Phyllopoda no division into a coxopodite and basipodite 

 stalk, from which two axially jointed divisions branch off,
