exposed shores it is most often to be found on rocks of coral in 

 small crevices and depressions receiving thus some shelter. A 

 single specimen was found in deep water (about 50 m.). The spe- 

 cimen was large, about 2 cm. high and occurred in a collection of 

 various other algæ which Dr. Mortensen most kindly sent me. 



Neomeris annulata seems to be rather common on the shores 

 of the Danish West Indies. I have specimens from St. Thomas, 

 the French wharf in the harbour at Charlotte Amalie, Bovoni 

 lagoon; St. Jan, off Ramshead (leg. Dr. Mortensen) in a depth 

 of about 50 m; St. Croix, Lime tree Bay.

As Howe has pointed out (I.e. 1905, p. 579), J. Agardh most 

 probably forgot his old description of this species from 1854 as in 

 1887 when writing his paper on the Siphoneae he had this alga 

 before him and then gave it the new name Botryophora. 



Of the original material collected by Ørsted at St. Croix 

 several (7) specimens are to be found in the Botanical Museum of 

 the University in Copenhagen; on the label which belong to them, 

 Ørsted has written: "Bryopsis??? Ad radices Rhizophorae Mangle 

 in sinu substagnante, Krauses lagoon, insul. St. Crucis" and above 

 it on the same label J. Agardh has written: "Botryophora Oerstedi 

 J. Ag. mscr. Genus novum". The fact that J. Agardh wrote on 

 this certainly the original label Botryophora Oerstedi is rather remar- 

 kable, as at the same time on the specimens he kept back in his 

 own herbarium he has written as already pointed out by M. A. Howe 

 „Batophora Oerstedi" and it is rather remarkable also, when he 

 (I.e. 1887, p. 139) writes: "Antea quam suum Dasycladum occi-
