This (Kemiebecasis) series here connects with that of the 
St. John River, previously given. 
From a comparison of the preceding lists some interesting 
conclusions may be drawn. ^ 
Of the species having the widest range may be mentioned 
Novicula Smithii, var. ovalis, a fresh water form, found at 
Ingleside, Nerepis, Milkish, Perry's Point, Harris’s Cove, 
iMillidgeville and the Narrows above Indiantown, but which 
also occurs in St. John Harl)or and Passamaquoddy P>ay. 
Navicula viridis and Tabellaria flocculosa, also fresh water 
forms, are widely distributed, but mostly at ])oints somewhat 
remote from the sea. The same is true of Stauroneis and 
Diatom a, essentially fresh water forms. On the other hand Dory- 
phora, (Raphofieis) Boeckii, a marine species occuring in Passa- 
maquoddy Bay, not only abounds in the Narrows of the St. John 
but is found also at Ingleside and Perry’s Point, as well as at 
other points in the Kemiebecasis. Collections from Flewelling’s 
Wharf, on the south side of the latter, are mainly made up of 
this species, while a second species, D. amphiccros, also marine, 
is much rarer, having as yet been observed only in St. John 
Harbor and Matthew’s or Harris’s Cove. Navicula maculata. 
Bail., a fresh water species, first observed in Florida, has been
