 PHYLLIDID.^. 



This family formed part of the order of Infero-oranchiata in 

 the arrangement of Cuvier, and has its place alongside of the 

 Pleurobranchidce (vol. iii. p. 557), from the members of which 

 group, among other characters, the mollusks composing it differ 

 materially in being provided with branchiae at both sides, and in 

 not being furnished with any shell, either internal or external. 



Dipiiyllidia, Cuvier. 



Animal oblong, fleshy, covered with an ample mantle, under 

 the borders of which the obliquely lamellated branchiae extend 

 along the two hinder thirds of the body. Head with minute 

 tentacles and a lobe-like veil. Vent at the right side behind the 

 reproductive orifice.
