 sent us a set of his second fascicle of Southern Ferns. The specimens 

 have the perfection for which Mr. Curtiss's preparations are famous, 

 and, as will be seen by the following enumeration, are of particular 

 interest: i. Pteris longifolia^ L.; 2. P. Cretica, L.; 3. P. aqtiiltna, 

 var. caudata^ the specimen consisting of lowest divisions of lowest 

 branches of plants 6-8 feet high; 4. P, serrulata, L, f., from the 

 grounds of Charleston College; 5, Adtantmn Capillus-VeneriSy L.; 6. 

 Asplenium deniahi7n,\^:^ 7. A, firmtim,}L\mz^\ 8. A.parvidmn^yidsX,

 copies in one package. Mr. Curtiss also offers a second series of his

and Adjacent Coast. By W. G. Farlow, M.D. (Reprinted from Re- 

 port of U. S. Fish Commission) 8vo, pp. 210, with 15 plates. Wash- 

 ington, 1881. — This long needed addition to our cryptogamic litera- 

 ture, although originally presented as a "report,'* is in reality a manual, 

 which, in a compact and more or less popular form, gives descriptions 

 of the different orders and species of sea-weeds '(exclusive of the Dia- 

 toms) found on our coast between Eastport, Me., and the State of 

 New^ Jersey; and, by means of which, any person visiting the seashore 

 within the limits just named can readily determine any of the forms 

 that may be found. To facilitate the work of determination, and to 

 enable amateurs who are little or not at all acquainted with our sea- 

 weeds to ascertain with some degree of accuracy the genera to which 

 the collected specimens are to be referred, an artificial key to genera ' 

 is appended to the descriptive portion of the text. Following the 

 introduction, which gives a resume of the Uterature relating to Amer- 

 ican marine algae and an account of the distribution of our species, 

 there is a short but comprehensive sketch of the general structure 

 and (^classification of sea-weeds, which will prove of special value to 

 the student, inasmuch as there is no generally accessible book in the 

 English language which gives a good account of the modern views of 

 classification and structure of these cryptogams. This portion of the 

 work concludes with full directions for collecting and preparing sea- 

 weeds, and then follow the descriptions of the orders, genera and 

 species. The descriptions of the species are exceedingly perspicu- 

 ous, and, in framing them, it has evidently been the author's inten- 

 tion, by avoiding technicality, to make his work as valuable to the 

 amateur collector as to the scientifice botanist. 



No one who contemplates visiting the coast for the purpose of 

 collectmg marine algae can well afford to go unprovided with this 

 work, which, we are informed, has been placed on sale at Mr Geo 

 A. Bates's Naturalists' Bureau, Salem. Mass.
