Dear Mr.Collins 
Thank you for th propmpt return of the list,and for the list of the species 
in the university collection . The names are largely those of the past,and the changes in 
nomenclature of algae have been full as frequent as in any other group of plants. 
Most of them I can make out so as to leave little doubt of what they are; but there 
are a few that I would like to see sometime, pf possible.Tery likely they are nothing new, 
but there is apossibility.The list is, 
Ectoearpus obtusangulus. 
allithamnion Rothii 
fi fasciculatus 
Pclysiphonia subtilissima 
Pclysiphonia subtilissims Cl adophora rupestris 
Ohylocladia subulatus 
Euthora cri stata, R. I . 
Dietniae 
Do you know what became of the collection on which was based Olney's Algae Bhodiaceae? 
Very Truly,
