Batters. — On Schmitziella , 
Batt., was consequently inserted in the Revised List of British 
Marine Algae 1 by Mr. Holmes and myself, and I partially re- 
wrote my notes on the genus with a view to their publication. 
While the Revised List was in the press I learned for the 
first time that Dr. Bornet had also found the plant, and named 
it in honour of Dr. F. Schmitz, of Greifswald. Being anxious 
that the name of Prof. Schmitz should remain associated with 
an interesting genus, which by its affinity with the Squamari- 
aceae recalls the work Prof. Schmitz has done on this group 
of the Florideae, I gladly adopted Dr. Bornet’s suggestion 
that the genus Schmitziella should be published in our joint 
names, and accordingly made the necessary alteration in the 
Revised List when correcting the proofs. 
The following is the diagnosis we propose for the new 
genus : — 
Schmitziella, Bornet & Batters. 
Thallus baud incrustans, endophytus, planus, membranaceus, 
pseudo-parenchymaticus, venosus, intra membranae laminas exteriores 
articulorum Cladophorae pellucidae extensus. Fructus sub cuticula 
Cladophorae in pustulis conceptaculiformibus hemisphaerico-de- 
pressis, apice poro pertusis, elevata evolventes, sparsi, minuti, 
pericarpio proprio clauso orbati, soros nematheciosos formantes. 
Thalli nervis primariis e cellulis elongatis pluri-seriatis (2-8), longe 
excurrentibus formatis, secundariis monosiphoniis pinnatim egredienti- 
bus, alternis, una cum praecedentibus reticulum efficientibus maculae 
cujus cellulis (ramulis) irregularibus plus minus densis implentur. Et 
carposporis et sphaerosporis paraphysibus paucis immixtis. Sphaero- 
sporis oblongis, zonatim divisis. Antheridiis ignotis. 
Schmitziella endophloea, Born. & Batt. 
Character idem ac generis. Sporangiis, 20 ft longis, 12 /x latis, 
aut binas aut quaternas sporas foventibus. 
Hab. in Cladophora pellucida , cujus thallum haud infrequenter colore 
pulchre coccineo tingit.
