 rudiments of flic (Ji<;taJ portion of the ap[>endaù-es. The coihlast is wcw

 the hand-like portion internal to the protuheranee.s from the o-cneral 

 surface of the subjacent body (fio-. 33). The banddike portions thus 

 cut off are the rudiments of tlie proximal [)ortions of the append- 

 ages. Three distal joints (f )ur in the last ambula.tory leg) are de\('lop-

Though the appendages (especially the anterior six p;urs) appear 

 almost simultaneously, yet by a close examinati«^n I f )und that the 

 fifth appendage a))pears first, and gradually firward; thefoiu'th, third, 

 second, and first appendages are formed ; then gradually backwards 

 the sixth, seventh, eighth, &e. appendages. The riKJiments of all the 

 appendages are almost alike. The order of the difi^^^vntiatit^n of the 

 distal [>ortion (round protuberances) of the appendages does not coin- 

 cide with the order of tlie appe:u'ance of the ap[)end;iges themselves. 

 The differentiation liegins at first in the fourth appendage, and ju'o- 

 ceeds in others successively to the first appendage, then graduallv 

 in the opposite direction in the fift'n and sixth appendages. From the 

 seventh appendage (inclusive) posteriorly, the second lateral rn-oove 

 is not formed. Thus all the abd«^minal appendages develop from 

 tlie banddike ])rominence-; and finally assume a leaf-like forîn. 



The six anterior appendages become afterwards chelate. The first 

 appendage does not develop as vigorously as tlie others, ft remains 

 small and slender and is afterwards placed l)efbre rhe mourh and l)e-
