The marine zoological station at Ban- 

 yuls-sur-Mer, France, has been the 

 scene of a series of experiments in sub- 

 marine photography carried on since 

 1893 by Dr. Louis Boutan. He has succeeded in photographing the ocean 

 bottom and various marine animals at moderate depths in which divers can work 

 with ease. He has also made a successful exposure with a camera at a depth of 

 50 meters, using the electric light for illuminating the screen photographed. 

 The apparatus used in this last feat is shown in the accompanying figure. The 



screen E receives light from the elec- 

 tric lamps at Z, supplied through the 

 cable C by storage batteries aboard the 

 boat. The shutter ob is maneuvered 

 through the same cable by electricity. 

 The author reviews the various attempts 

 made to overcome the considerable diffi- 

 culties, and reproduces in the plates the 

 results thus far attained. Suggestions 

 are made for a simple camera for amateur submarine photographers and for work 

 in aquaria. A brief historical sketch of photography is also given. c. a. k. 



These two books are mutually supple- 

 mentary and both are indispensable for 

 the seaside naturalist. The first deals 

 with the commoner invertebrate forms 

 of our Atlantic and Pacific coasts, and 

 is a manual with systematic arrange-

second is a seaside natural history with brief keys for the determination of some 

 of the common types of marine life and with full accounts of the habits of numer- 

 ous species, and notes upon their structure. Miss Arnold's admirable book will 

 be a welcome aid to teachers and amateur collectors at the seaside, while Miss 

 Newbigin's will afford a more readable account of the more interesting phases 

 of marine life. c. a. k. 



This is an exhaustive paper dealing 

 with the structure and function of the 

 otocyst of the shrimp, the prawn, the 

 crayfish, and the crab, and its development in the lobster. The shrimp, 

 Palcemonetes , is easily kept in aquaria without running water and lives equally
