The material of this species is somewhat scanty, but ample for identification. The 
scarcity, however, is explicable in view of the inconspicuousness of the calcified plant to 
any eye but that of the expectant algologist. The species issynonymous with WV. Kelleri, 
Cramer, and has been recorded from the West Indies, Polynesia, and Mauritius. If 
carefully searched for it will probably be found at other tropical stations. Mr. M. A. 
Howe (/. c.) has published a useful key to the three species of Neomeris and has given a 
bibliography of the literature.
