/S. quinnia and $. condensate*, a Mesocarpus, or, as the case might 

 be, a Staurospermum, a long-celled Zygnema, three forms of fficfo- 

 gonium, one very slender, another less so, and a thicker nearly 

 square-celled species, I believe all quite distinct ; but none (as men- 

 tioned) showed fruit. The contents in all cases were considerably 

 altered and collapsed. Zygogonium delicatulum and Conferva 

 lombycina made their appearance. A very slender Vancheria also 

 showed itself. Microtkamnion Kuetzingianum was present (a very 

 minute but, at home, common-enough little alga, of uncertain 

 position). JPediastrum JBoryanum and P. ellipticum showed them- 

 selves. Of Desmidiese the representatives were very few and 

 minute — a Closterium very like C. parvulam, Nag., but more 

 slender, a minute Cosmarimn, generally referred as a variety of 0. 

 MenegMnii, also C. crenatum, Nag. (?). Of Phycochromophycese, 

 a macerated Nostoc (or Nostoehaceous alga) also occurred, as well 

 as a Scliizothrix and Tolypothrix distorta. 



There were a number of Diatoms already described by the Rev. 

 E. 0'Meara(Contrib. xxviii.). The empty carapace of a Vaginicola 

 was here and there to be met with. 



From this it may safely enough be assumed that the character- 

 istic freshwater-algal flora of that remote region is very much 

 the same as our own. Of course it is quite possible that a diligent 

 search at different seasons might yield certain rarities or some 

 novelties *,

(1) Algcd from the JVeigJibotirJiood of Torres Straits. 

 Mr. Moseley 5 s note accompanying the specimens is here quoted : 



* [The above conclusions of Mr. Archer seem at variance with the researches 

 of Mr. P. F. Eeinsch, who describes as new to science three genera and some 

 thirty species of freshwater Algte from Kerguelen's Island (vide Journ. Linn. 

 Soc. Bot. vol. xv. pp. 205-251). Doubtless the longer stay and hence greater 

 opportunities afforded for collecting to the Kev. A. E. Eaton in the Transit- 

 of- Venus Expedition, above referred to, may to some extent account for the 

 paucity and non-rarity of the specimens obtained by the 'Challenger' Expedi-
