In full-grown specimens the four tentacles are equally developed, but (luite young specimens have only one tentacle (a "Stcciistnipia" or "Euphysa" stage). During the growth of the medusa the three other tentacles develop one by one, so that we may find stages with two, three, or four tentacles of different sizes, until at last, in the final stage, they all attain full size (see Kranip & Damas 1925). â Through Euphysa tentacidata (whidi when fully developed possesses three tentacles, one large and tw^o smaller ones) the present species is so closely connected with the well known Euphysa aurafa that we shall have to unite them within one and the same Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Danish Ingolf-Expedition (1895-1896); Københavns universitet.
