most kindly sent me, I have found a small remarkable Floridea 

 which in its habit reminds one very much of Lomentaria articulata 

 Lyngb., but nevertheless it does not quite agree with this species. 



During a stay in Paris I showed my plant to Dr. Bornet. 

 On looking into Herb. Thuret. a specimen w^as found which seemed 

 to agree rather well with my plant. It was gathered at Guadeloupe 

 by Mr. W. Schramm and was marked "Herb. Grouan Nr. 277" 

 and determined as ^^Chrysymenia lomentaria Grouan". It is not 

 mentioned in Maze et Schramm, "Essai de classification des 

 Algues de la Guadeloupe". 



Further in Herb. Thuret two other specimens seemingly of the 

 same plant were present and both were sent to Dr. Bornet from

Professor Farlow of Gambridge; they had been collected by him 

 at the Bermuda Isles. These specimens in Plerb. Thuret, of which 

 I have the loan from Museum d'Histoire Naturelle, in the collections 

 of which Herb. Thuret is now incorporated, have on a more 

 detailed examination proved to be identical with my specimen from 

 St. Jan. 



Later also I have received from Professor Farlow another 

 specimen from the Bermuda Isles and Prof. Farlow has also most 

 kindly sent me a preparation of alcohol material, by means of 

 which I have been able to make a more thorough examination 

 than is possible with dried material. 



Moreover Prof. Farlow, who had determined the specimens 

 in Herb. Thuret as "-Chrysymenia ?", has informed me that the 

 plant in question is most probably identical with Chylodadia
