be located accurately, the seasonal samples between were given dif- 

 ferent station numbers. The station numbers (1-13) shown in figure 

 1 for traverse 3 are plotted from the first time the traverse was 

 sampled. The traverses, sampling times, and station numbers are as 

 follows :

Most of the stations were sampled by means of a small coring tube 

 3.5 cm. in diameter. A few centimeters of water above the sediment 

 water interface and the top centimeter of the core were placed in a 

 jar with neutralized formalin at the time of collection. The second 

 centimeter of the core was removed for particle-size analysis. At 

 those near-shore stations that have a sandy bottom a snapper-grab 

 sampler was used. About 10 ml. of wet sediment was removed from 

 it and preserved for foramini feral analysis. An additional 10 ml. was 

 obtained for particle-size analysis.

The pH of the preserved samples was checked periodically. None 

 of the samples became acidic during the duration of their storage. 

 When the sediment in a sample jar had settled sufficiently, the sedi- 

 ment level was marked with tape. The biological stain Rose bengal, 

 the properties of which are discussed by Walton (1952), was added 

 the day before examination of the material. After staining, the
