SMITHSONIAN MISCELLANEOUS COLLECTIONS

took part. During the first cruise observations were made at 30 

 stations, that is, 8,336 to 8,365 inclusive. These stations extended 

 from the lower bay to the mouth of the Patajjsco River, while 

 during- the second cruise 35 stations were examined, Xos. 8,366 to 

 8,390 inclusive, which approximately covered the same parts of the 

 bay examined during the first trip. The efforts of the members of 

 the Museum staff were directed to the securing of bottom samples 

 and bottom life, the hydrographic work being done by the repre- 

 sentatives of the Bureau of Fisheries.

The results of these two cruises indicate a remarkable scarcity 

 of animal life, the washing of an entire dredge haul frequently 

 yielding only a handful of shells, worms, and small crustaceans. The 

 bottom material consisted chiefly of mud in a semi-fluid condition, 

 which appears to be discouraging to animal life. A few notable 

 exceptions were encountered in what one might term garden spots 

 in which a decided concentration of living organisms was encountered. 

 No shore collecting was done.
