Occurrence of C/iramatoncma rubrum Fewkes in the northern Atlantic. mena have been observed on the west coast of Greenland, and this nia\- account for the appearance of this oceanic deep-sea medusa comparatively near the coast and swinnning at the surface of the water. The hydroid stage is unknown, and no young stage of the medusa has been observed; it is impossible, therefore, to state, or even to guess, anything with regard to the development of the .species. Related Species. â Bigelow (1909) has described a similar medusa from the eastern tropi- cal Pacific (the Humbolt-Current off the coast of Peru, in intermediate strata). He called \\. Ptychogena erythrogonofi. Bigelow possessed a series of specimens in different stages of growth, the largest being 38 mm in diameter by 25 mm high. The general appearance of the species bears a striking resem-.
