Although the type of this species comes from the same station where that of tylota was taken, the two species are so unlike they can not be confused. Specimens of diaphora show great diversity in the number of disk granules and arm spines, in the size and form of the radial shields, which may be quite small and indistinct in.

Young specimens might, however, be confused with the next species, owing to their having only four or five arm spines and few disk granules. OPHIOLEBES PAUCISPINA, new Disk 7 mm. in diameter; arms about 22 mm. long. Disk covered with coarse, thick scales, some of which bear rounded granules. Radial shields moderate, rounded, well separated from each other. Upper arm plates thick and more or less swollen, rounded, triangular or rhombic; except first two, separated from each other.
