Dr. D. H. Storer read a description of a new species of 

 Syngnathits, brought from the western coast of California 

 by Capt. Phelps. 



Syngnathus californiensis. Reddish brown, lighter beneath : 

 the lower portion of the sides irregularly dashed with white ; 19 

 transverse plates anterior to the vent, and 47 plates posterior to 

 it. From the tip of the tubular mouth to the posterior edge of 

 the operculum, the length is rather more than one seventh the 

 length of the fish. The greatest depth of the jaws is rather less 

 than one half the depth of the head. The dorsal fin commences 

 on the anterior third of the body, and the height of its rays is 

 less than one third the depth of the body.

 melanoleuca, magpie, from the North-West part of Michi- 

 gan, presented to the Society at the last meeting.

 measurements of this specimen and European specimens of the 

 same bird, Dr. Cabot had instituted a careful comparison between
