Ophioylypha gracilis, sp. n., Sars, 1. c. pp. 18-22, Lofoden I., Bodo, Drbbak, 
100-300 fath., is regarded by Liitken (16, p. 103) as a southern dwarfed 
variety of Ophioctcn kroeyeri. 
Ilemieuryale. Ljungman (13) and Lyman ( 16) agree with Liitken that this 
genus is not an Euryalid, but a true Ophiuroid. Ljungman places it in this 
group, where it occupies, however, a peculiar position. Opkiura cuspidifera, 
Lmk., is to be referred to it (Lyman, 1. c.). 
Ophiacanthino. 
The validity of Ophiothamuus and Ophiomitra, Lym., as distinct from Ophia- 
cantha, is contested by Liitken (15, pp. 101 & 102). Ophiothamnus affinis and

Ljungman (13) gives a synopsis of the Atlantic species of Amphiura and

ljungman follows Sars (19) in including in the subgenus Ophiopdte [-^/s] 
not only O. securigera, B & K., and O. borealis, Sars (/. c. pp. 15-17, Bodo, 
Lofoden I., 80-300 fath.), but also Amphiura jiliformis and allied species 
(sarsi, atlantica) without ambulacral papillae. Ophiocnida is restricted to 
A. brachiata, and Hemilepis introduced as a section of Amphiura with two very 
small (sometimes rudimentary) ambulacral papillae and the ventral side of the 
disk almost naked (A. semiinermis,jlexuosa, latispina, kinbergi). Ophiocnida (?)
