GenbrAj Species, &o., referred to. 
Noctiluca miliaris. No cilia. A granular mass reaching from nucleus 
to the striped tissue of the flagellum probably acts as a nerve, as curare 
inhibits the action of the flagellum ; electricity tetanizes it. Phos- 
phorence increased by warmth and mechanical means, unaffected by 
electricity. Flagellum probably used to obtain food, not for motion.

C. Robin, 0. R. Ixxxvi. p. 1482, on Noctiluca^ states that disappearance 
of the flagellum, &c., in N. miliaris i^ a constant phenomenon, due to 
atrophy ; the nucleus takes part in the segmentation of the body, which 
occurs by dichotomous fission ; it becomes elongated and longitudinally 
striated, the two ends become globose, and the thin connecting band is 
then broken. At the same time the peripheral protoplasmic threads 
aggregate into a layer, which becomes constricted and pushed inwards, so 
as to fuse with the perinuclear protoplasm which has segmented, thus
