Since the llnorescence is less stahle in this species than 0. californica, similar histological studies were not attempted. Emission .v/vr/n/ The luminescent emission spectra of Of^liiopsilu calijornica and .InipJiipliolis squamata {'Fit;'. '•) are extremely hroad with a similar approximate maximum at 510 nm and a half band-width of 71 nm. The emission spectra did not (lifter with chemical, mechanical, or electrical stimulation. In 0. californica there was also no detectable difference in emission spectra from tan or brown pigmented bands. The spectra were not fully corrected tor system nonlinearities, but the peak and qualitative features such as breadth are reliable. The green emission of the in i'it'0 fluorescence is visually identical to that of the luminescence. DISCUSSION The luminescent emission spectrum reported for 0. califonrica in this paper has a peak at 510 nm and lacks pronounced shoulders. This differs from the previous report of a peak- at 525 nm with a pronounced shoulder at 485 nm (Brehm ct a!., 1973). These differences in spectra can only be ascribed to vari- ability between animals. Wampler (1977), using" as yet unidentified species of ophiuroids, reported a peak at 518 nm with shoulders at approximately 496 nm.
