Colaconema Bonncmaisonice, Batt. in lit., was first recognised in the 

 " fruiting " condition (monospores) in a fragment of Bonnemaisonia 

 asparagoides, dredged ofY the Eddystone Lighthouse on the 9th 

 September. It was made the type of a new genus of endophytic algse. 

 On the same expedition the interesting Desmarestia Dresnayi, Lamx., 

 was obtained, and in the perfect condition, i.e. with a main frond, having 

 two smaller lateral fronds near the base, symmetrically placed one on 

 each side. Subsequently, in adjacent waters, 26th September (haul 34), 

 a very fine specimen of the same plant was secured. 



Colaconema Chylocladice, Batt. in lit., was recognised in fruiting 

 condition (monospores) in a tetrasporogenous specimen of Chylocladia 

 ovalis, dredged in Bovisand Bay, 20th September. Well-" fruited " 

 specimens of this species had previously been obtained by ]\Ir. Batters 

 at Torquay, althougli he had not named, or pulilished, his find. 



Colaconema reticulatum, Batt. in lit., was found on a very broad old 

 frond of Desmarestia Dresnayi, Lamx. ; but as its reproductive organs 

 have not yet been recognised, it is only tentatively placed here in the 

 classification. It had previously been found elsewhere by Mr. Edward 

 Batters. 



Trailliella intricata, Batt. in lit., has been made the type of a new 

 genus, on account of the discovery of the tetraspores of the plant. 

 This alga had already found a place in the classification as indicated 

 in the above list. As it was placed from barren specimens, the 

 discovery of the tetraspores, which are unique in position and mode 

 of development for the Caliihamnions, rendered re - classification 

 necessary. It was named in honour of Mr. G. W. Traill, the well- 

 known Scottish algologist.
