stance, as a fragment of wreck, for instance, but to a spherical, 

 fleshy receptacle, apparently a portion of their own system. This 

 receptacle was of a light, yellowish color, about the size of a small 

 orange, which it somewhat resembled in aspect. To it were at- 

 tached, by the usual flexible pedicles, about a dozen Barnacles, 

 allied to Anatifa, as above indicated, but differing from it in the 

 breadth of the dorsal plate, and in the projection of a strong keel 

 at the base of both dorsal and lateral plates. When this specimen 

 was procured, myriads like it covered the sea for miles in the track 

 of the vessel. Barnacles aggregated in this manner of growth do 

 not appear to have been hitherto reported.

Mr. Bolander stated that he had recently collected two grasses 

 believed not to have been before found on this coast, though com- 

 mon in the Atlantic States, viz. : Paspalum distichum (L.) along 

 the shores of Clear Lake, covering large patches of ground, and 

 Leersia oryzoides (Swartz), along Cache Creek, of much larger 

 size than he had met with in the East. He believed Grastridium 

 australe, which covers almost every dry hill in the interior, to be 

 indigenous. 



Dr. Behr made some remarks on the date of introduction of some 

 foreign plants, now becoming very common in this vicinity, which 

 he intends to make the subject of a future article.
