1 This remarkable and abnormal type of Asterid [Pythonaster muirayi] is altogether unlike any other form. Its 

 general morphological structure appears to me to justify its inclusion in the family Pterasteridas. Its aberrant 

 peculiarities, however, necessitate in my opinion its separation in a distinct sub-family. — (Sladen, Zool. Chall. Exp., part 

 51, p. 531.) 



2 Ophioglyplia meridional/is is the southern cousin of Ophioglypha robus'a, from which it differs in shorter arm spines, 

 more swollen disk scales, smaller mouth papilla?, and fewer tentacle scales. — (Lyman, Zool. Chall. Exp., part 14, p. 41.) 



' d The specimens [of Ophiomvbsium lymani] from the widely separated stations showed certain minor differences. 

 For example, those from Station 235 [Japan] had more arm spines and rather more numerous lower disk plates, and 

 the tentacle scales were entire, instead of divided. I have deemed it best to keep the varieties together for the present. 

 — (Lyman, Zool. Chall. Exp., part 14, p. 90.) 



4 This singular genus [Ophiomyces] stands quite by itself, unless we compare its curious mouth papilla; with the 

 spatula-like tentacle scales of OpMopsila. All the specimens I have seen had a tendency to raise the arms above the
