Botany and Zoology. 327 



as it does, the results brought out in his previous " essays " in 

 this subject, we may say that Professor vanTieghem appears to 

 us to have indicated some of the main lines upon which the 

 system of the future will be founded. As Sir Joseph Hooker 

 said, in substance, long ago, the Natural System which is to 

 express the relationships of plants faithfully, must wait until 

 much more has become known in regard to the structure, develop- 

 ment, and behavior of all plants. And, even then, the Natural 

 System will present the conditions only for the time, since 

 changes in structure, mode of development, and behavior are 

 constantly taking place. g. l. g. 



3. The Botanisches Centralblatt, under its new management, 

 preserves the best traditions of its former excellence and has, at 

 the same time, considerably increased its range. Dr. Lotsy, of 

 Leyden, the editor in chief, is fortunate in having the services of 

 'a goodly number of careful writers of abstracts, and he is now 

 confronted with the serious task of judicious sifting what they 

 report. Many persons are watching with interest the manner in 

 which he will reduce to their proper places the notes which pos- 

 sess no scientific importance, in order to make room for refer- 

 ences to contributions having permanent value. Up to the 

 present time this work of selection has been done in such a way 

 as to promise well for the future. g. l. g. 



4. Additions to the launa of the Bermudas from the Yale 

 Expedition of 1901, with Notes on Other Species; by A. E. 

 Verrill. Trans. Connecticut Acad. Sci., xi, pp. 15-62, pi. i-ix, 

 1901. — In this important paper Professor Verrill records some of 

 the results of his second expedition to Bermuda. A large num- 

 ber of species, including representatives of almost every group 

 of invertebrates, as well as several fishes, reptiles and mammals, 

 are here recorded which have not before been found on the 

 islands. Many species of invertebrates, including especially the 

 Tectibranchiate and Nudibranchiate Mollusks, Planarians, and 

 Anthozoa, are described as new to science, and figured from 

 drawings and photographs. w. r. c.

(2) Comparisons of Bermudian, West Indian, and Brazilian 

 Coral Faunae y by A. E. Verrill. Trans. Connecticut Acad. 

 Sci., xi, pp. 169-206, pi. x-xxxv, Dec. 1901. — Some of the results 

 of Professor VerrilPs studies on the reef corals carried on during 

 the past forty years are included in these two articles, which 

 together form a most important monograph on the subject. 



A number of the names of genera have been changed in accord- 

 ance with the rules of priority. One of the most important 

 instances is the adoption of Mceandra (Oken, 1815) in place of 

 Mmandrina (untenable for this group), and the union of Diploria, 

 Manicina, Cosloria, and Leptoria with it. 



Another instance is the uniting of Mussa, Symphyllia, Iso-
