phyllia, and part of Ulophyllia, under Mussa, the earliest name. 

 Another important change is the adoption of Acropora (Oken) 

 in place of Madrepora (Linne), and the transfer of the latter to 

 Lophohelia (E. and H.). All West Indian forms of Acropora 

 are united under A. muricata (L.), but a large number of forms 

 are admitted as named varieties, some of them newly described. 



The extended and detailed character of the generic and spe- 

 cific descriptions, and the excellence of the illustrations will serve 

 to determine beyond question the species and varieties referred 

 to, and this is of especial importance in a group where dis- 

 tinguishing diagnoses are more than ordinarily difficult to estab- 

 lish. Habits, methods of growth, geographical distribution and 

 appearance of the living coral are included in many instances. 

 The Bermudian coral-fauna " must be regarded as a detached 

 colony of the more hardy species which have migrated from the 

 West Indies through the agency of the northward currents, by 

 which their free-swimming larvae have been carried," although 

 certain very common West Indian species are absent while others 

 of the same genera are present in abundance. The West Indian 

 coral-fauna is directly related to that of Brazil, although very 

 few species are strictly identical. It is, however, totally distinct 

 from that of Panama and the Indo-Pacific region. A few species 

 may be identical with forms from the eastern Atlantic. The few 

 knowm Brazilian reef corals present remarkable archaic characters 

 indicating an ancient fauna that has mostly disappeared. 



Especially noteworthy are the twenty-six beautiful plates of 

 photographic reproductions which illustrate both papers. These 

 represent the new species and varieties, as well as typical speci- 

 mens of the common species. Many of the type specimens of 

 Dana, Verrill, and others, preserved in the Yale Museum, and 

 also rare species from the American Museum, New York, are 

 included. 



A considerable number of East Indian and Pacific Ocean corals 

 are also described and figured, including several new species.

6. Some Spiders and Mites from the Bermuda Islands ; by 

 Nathan Banks. Trans. Conn. Acad., vol. xi, pp. 268-275, 

 January, 1902. — This is a catalogue of the spiders collected by 

 the Yale parties in 1898 and 1901 with their distribution, and 

 with revised lists of the species previously recorded. The num- 

 ber of species collected in 1898 and 1901 was 28. The total 

 number now known from the islands is 33. In this paper three 

 new species are described. 



7. The Marine and Terrestrial Isopods of the Bermudas, with 

 Descriptions of JVew Genera and Species ; by Harriet Rich- 

 ardson. Trans. Conn. Acad., xi, pp. 277-310, with 4 platen, 

 January, 1902. — This memoir is a nearly complete monograph of 

 the Isopods of the Bermudas, for it contains revised lists of the 

 few species previously recorded, as well as descriptions and 

 figures of numerous new species. Of the marine forms IS
