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

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

 peculiarities, however, necessitate in my opinion its separation in a distinct sub-family. — (Sl.\dex, ZooL Vhall. Exp., part 

 51, p. 531.) 



^ Ophioijlyplui mundwaalu is the southern cousin of Opldoylyplia robusla, from which it differs in shorter arm spines, 

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



3 The specimens [of Ophiommiwni lytmai] from the widely separated stations showed certain minor differences. 

 For e-tample, those from Station 235 [Japan] had more arm spines and rather more numerous lower disk plate.^, 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.) 



* This singular genus \()phiomyce.<i\ stands quite by itself, unless we compare its curious mouth papilla; with the 

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