series of three well-drawn plates illustrates the book. The 

 work on the Ophiuridce is a supplement to an elaborate cat- 

 alogue by Mr. Lyman, published about six years ago, and in- 

 cludes many additional species, especially some forms ob- 

 tained in the deep-sea dredgings oif the Florida coast. The 

 work, like its predecessors, is intended to include the litera- 

 ture of the subject to date, in addition to descriptions of new 

 species actually exhibited in the Museum of Comparative 

 Zoology. 



MARINE AQUARIUM AT BRIGHTON. 



The great marine aquarium at Brighton was formally 

 opened to the public on the 12th of August, on the occasion 

 of the meeting of the British Association for the Advance- 

 ment of Science at that place. This establishment is the 

 largest and best appointed of its kind in the world, and has 

 been planned with the sole object of presenting the wonders 

 of the sea in the most complete and attractive manner possi- 

 ble. The building is 715 feet in length, with an average 

 width of 100 feet. Its front consists of five circular-headed 

 arches, connected by terra-cotta columns. The exterior of 

 the aquarium is highly ornamented, and presents a very strik- 

 ing appearance. The interior is arranged with a view of fur- 

 nishing accommodations of ample extent for all the varieties 

 of marine life likely to be brought within its inclosures. The 

 aquarium proper is divided into three corridors, the first sub- 

 divided into nineteen bays, and covered by a groined roof of 

 brick. Its extreme length is 220 feet, broken by a central 

 square 55 by 45 feet, in the centre of which is to be placed a 

 terra-cotta fountain of elegant design. Fourteen tanks are 

 ranged on each side of this corridor, varying in dimensions 

 from 55 by 30 feet to 11| by 20 feet. The largest of all, 

 which occupies the whole north side of the square, is over 

 100 feet in length, capable of accommodating a whale of con- 

 siderable size. The front of the tank is composed of Port- 

 land stone, ornamental iron, and heavy plate glass, secured 

 by water-proof cement. 



The second corridor is 80 by 23 feet. It has no tanks, its 

 main purpose being to serve as an approach to the conserva- 

 tory, the first corridor, and the terrace. The third corridor 

 is 23 feet wide and 160 feet long, and contains twenty tanks,
