NOTES AND LITERATURE.

The same author, {Bull. Amer. Mus. Nat. Hist., Vol. XVI, pp. 

 3 2 3~33 2 ) ca lls attention to the great importance of boring algae as a 

 factor in the disintegration of corals. These grow most vigorously 

 in quiet lagoons and thus contribute to the rapid decay of corals 

 known to take place in such situations. They are, therefore, to be 

 reckoned among the numerous elements concerned with the formation 

 of coral islands. 



The crustacean fauna of Nickajack Cave, Tennessee, has been 

 investigated by W. P. Hay {Proc. U. S. Nat. Mus., Vol. XXV, pp. 

 417-439). A new species of Caecidotea, closely related to C. 

 nickajaskensis Packard, a new species of Gammarus, and two new 

 subspecies of crayfishes are described. 



Notes on the structure and development of a species of barnacle, 

 Dichelaspis miillcri, found parasitic on the gills of crabs, have been 

 published by R. E. Coker {Bull. U. S. Fish Com. for igor, pp. 399- 



BOTANY. 



Mcllvaine and Macadam's "American Fungi." 1 — A second 

 edition of this book, which appeared first in 1900, has been brought 

 out, and differs from the original edition in the addition of a supple- 

 ment of twenty-five pages, including one full plate and several cuts. 

 There is no equally full and fully illustrated book on the edible and 

 poisonous fungi of this country, and though bulky and somewhat 

 inconvenient for use, it is much lighter than the original issue and it 

 ought to be in the hands of all who collect fungi for the table.

Notes.— Postelsia, the new yearbook of the Minnesota Seaside 

 Station, makes its appearance in a very attractive form, in the issue

 ters, or lectures, illustrated. 



A new periodical, Annates Mycologici, under the editorship of 

 H. Sydow and devoted to Fungi, is announced to appear at the 

 opening of 1903, through the book house of R. Friedlander and 

 Sohn, of Berlin.
