comprising Psammechinus , Gymnechinus, Toxopneustes , Tripneustes , 
Sphaer echinus, Pseudoboletia, Pseudocentrotus ; Mortensen (229) p. 135. 
[Pomel did not use the name Schizechininae, nor could he well have 
done so since he made Schizechinus s.-g. of Anapesus\ neither should 
Mortensen use the name, since for him Schizechinus is syn. of Psam- 
mechinus ; the name should be Toxopneustinae.]
