APODID^E. 259 



Okder I. PHYLLOPODA* 



Body naked, or with only the head and thorax covered 

 by the carapace; feet many, from eleven pairs to sixty; 

 joints foliaeeous and gill-like, chiefly fitted for respiration; 

 eyes two or three, in some placed at the end of movable 

 pedicels; antennae one or two pairs, generally small, and not 

 assisting the animal in swimming; mandibles generally 

 without palpi. 



Fam. APOBIDM, Baird. 



One pair of antenna?, short and styliform; eyes two, 

 sessile ; young only with one eye ; feet sixty pairs, all 

 branchial ; nearly the whole body covered by a large shield- 

 shaped carapace ; body formed of numerous rings. 



Dr. Baird observes, "The number of articulations or 

 separate pieces of which the body of these animals is com- 

 posed, is extraordinary. Schseffer, with wonderful patience, 

 undertook the task of counting them, and in a table, in 

 which he enumerates them seriatim, reckons the number to 

 be 1,802,604 ; and Latreille says that we may safely take 

 them to be not less than two millions" (Brit. Ent. p. 25).
