OosporciC and Floridac. The first order contains the simplest forms, 

 such as Clathrocystis, which Dr. Farlovv has proved to be the cause of 

 the red color of some of the codfish cured at Gloucester, and the 

 Nostochincie, which are arranged after I'huret. The second order 

 includes all the grass-green algos except Vauchcria, and with them are 

 also placed the Phceosporccr. which suborder includes Laminaria, 

 Agarum and Alaria as well as several tribes of less conspicuous olive- 

 brown alga;. The third order is made up of the Vauchcrica. and 

 Fucacccc; and the fourth is very nearly coincident with Harvey's i?/!r'^f- 

 spcrmar. This system embraces all that is good in the arrangement 

 ])roposed by Cohn, and gives moreover a definite place to some 

 families which that author knew not how to dispose of. The paral- 

 lelism to Oosporic, Zygosporic, Carposporic, etc., Fungi is not dwelt 

 upon, nor even mentioned. It is to be hoped that future studies may 

 separate the Vaucheriece. from the Fucaccce, as they are widely different 

 in structure, habit and color, and even the mode of producing oospores 

 is not very similar in the two groups. Then the Fitcacea could take 

 rank as an order, which would be more befitting their general char- 

 acter. As there has been no thorough revision of the New England 

 Algce since the publication of the Nereis, nearly thirty years ago, a 

 good many minor changes are introduced, and corrections made. The 

 number of additional species is considerable, but with the exception 

 of a Fiiciis or two, a Laminaria, a new Neinastoma, several CoraUina- 

 cclc, a Dityosiphon and four species of Mo)iosfroma, they are mostly 

 minute or obscure forms, which would escape the notice of a less 

 practised algologist than Professor Farlow. An introduction of 

 twenty-four pages gives the reasons for the classification adopted, and 

 contains many hints which will be very useful to the collector and 

 the student. The latter will find at the end of the book an excellent 

 "Artificial Key to the Genera," and a cood list of the works consulted 

 in the jireparation of the report. Altogether the work is thorough 

 and scholarly ; it refiects high credit on the author, and it will be of 

 very great use to students of these interesting and beautiful plants.- —

Aiinileii'ijl clirySfUltha.— Every botanist knows that a label 

 will sometimes get misplaced, especially in the sometime hurry of col- 

 lecting, and that error will creep in at times in spite of the best efforts 

 at accuracy. It was only in view of these well known chances that T 

 suggested in Vol. IV, No. i, that there might be some mistake abcut 

 the [Tlant which Mr. Marcus E. Jones found at Colorado Springs, 

 which had the flowers of A. civntka and of ^. c/iiysantJia all on one. 

 My chief reason for making the suggestion was that I had made some 

 careful collections in that vicinity in 1S71 and in 1873, andmany good 

 botanists had also collected there, and it seemed that so large and so 

 showy a plant should have been readily seen by some one. As Mr. Jones 

 subsequently Wrote that he could not be mistaken, there would seem 

 to be no need of any further record in the matter. I would however 

 like to do him the justice to say that a correspondent sends me
