PHOTOPHORES OF DECAPOD CRUSTACEA 353 Immediately behind the reflector formed by the proximal granular masses of the photogenic units is situated a conical mass of nuclei (Fig. 24, n.) which differ from all other adjacent nuclei. They are closely crowded and are deeply staining, showing a prominent nucleolus, and being larger than the nuclei of the chitogenous epithelium, which in my preparations show no obvious nucleolus, they are readily. phot add. phot nv.
