4. ASTEROIDEA. 
Perrier (4) adopts the following classification of Stellerids : — 
1. Forcipidatce. Pedicillariae straight and crossed, one of the two 
forms at least present (pp. 72-100). ( Brisingidcc , Pedicill- 
asteridce , Aster iadce.') 
2. Spinuloscc. Skeleton composed of small ossicles carrying little 
mobile spines, often grouped into “ pedicillaires en pince.” 
Lateral plates not differentiated, or small (pp. 100-125). 
( Echinasteridce , Asterinidce , Solusteridce.) 
3. Valvulatcc. Skeleton powerful, often in mosaic, covered with 
calcareous granules, and often carrying valvular pedicillarite. 
A double row of large marginal plates (pp. 125-129). ( Goni - 
asteridce.) 
4. Taxillosce. Ossicles of the skeleton often prolonged into little 
projecting columns carrying a bunch of spines, which can be 
differentiated into pedicillariae with one or two branches.
