It occurs in shallow water and mostly in more sheltered places, but it is also found in somewhat exposed localities. In the last mentioned places where the light, too, was strong some specimens were gathered which were covered quite densely with long, unicellular, hyaline hairs. These hairs serve most probably as a protection against strong light*) being present in so many littoral algæ and non existing or less deve- loped in those from deep water

These hairs serve most probably as a protection against strong light*) being present in so many littoral algæ and non existing or less deve- loped in those from deep water. That the hairs, on the other hand, also may serve as absorbing organs of nutriments, is very likely**). Hypnea mnscijormis is often an epiphyte upon larger algæ and occurs commonly entangled among other algæ to which it fixes itself by means of the tendrils. Specimens with tetrasporangia were found in the month of February. St. Croix: Christianssted's harbour, Christianssted's Lagoon, Lt.
