MISCELLANEOUS COLLECTIONS. 



With but two exceptions the miscellaneous collections were made by Prof. J. O. 

 Snyder, of Stanford University, during the progress of biological investigations of the 

 coastal streams of California and Oregon carried on during the summers of 1897 and 

 1899. One of the exceptions referred to is a collection, consisting of but three specimens, 

 which was made by the writer in 191 5 at Hope Island, Puget Sound, Wash. The other 

 exception is one specimen which was collected in the ocean at Half Moon Bay, Calif., 

 some 20 miles south of the mouth of the Sacramento River. 



The collections from the coastal streams are for the most part small, and a detailed 

 consideration of each collection will be unnecessary. Measurements of the scales were 

 not made. The data are presented in the following table (44) :
