Near Sauta Barbara, the outcrop (C^) upon the seabeacb afforded a 

 few fossils, some of which were similar to species obtained from the San 

 Diego well. Among these were the following, all recent species : — 



Venericardia monilicosta. 

 Bittium quadrifilatum. 

 Bittium asperum. 

 Lacuna vincta. 



Astyris gausapata. 

 Ainx)Mssa versicolor. 

 Trophon orplieus f juu. 



The formation within whose limits the beds above described are to be 

 included extends from the Pribiloff Islands southward, at least to Yesso 

 Island, Japan, on the west, and to Chili on the east. A fruitful locality 

 is at Cerros Island, Lower California, from whence Waldheimia Kennedyi 

 Dall, and also a number of the species referred to in the preceding 

 article, have been obtained, some of which are described by Gabb in the 

 Paleontology of California. 



Jurassic or Cretaceous beds appear to exist at Todos, Santos Bay, 

 Lower California, not far from San Diego. Mr. Hemphill collected here, 

 and has presented to the National Museum, half a dozen species not yet 

 critically examined, but containing a fine specimen belonging to the 

 Budistce, which have hitherto been hardly known as American fossils.

A REVISIOIV OF THE AITIEKICAIV SPECIES OF TBE OENUS BBE-

By O. BKOWIV GOODE. 



The type of the genus Brevoortia of Gill is the species described in 

 1802 by Latrobe under the name of Clupea fyrannus, and later by Mitch- 

 ill under the name of Clupea menhaden. As has been already indicated,* 

 the former name has the prior claim to adoption, and the species must 

 be called Brevoortia tyr annus. Of this species, there appear to be two 

 geographical races or varieties. One of these is the typical form of the 

 Atlantic coast of the United States, the other a closely allied form from 

 the coast of Brazil, already described by Spix under the name of 

 Clupanodon aureus. For the northern form, the name of Mitchill should 

 be retained, and the two varieties may be distinguished as Brevoortia 

 tyrannm var. menhaden, and Brevoortia tyrannus var. aureus. On the 

 coast of Patagonia and Paraguay occurs a well-marked species described 

 by Jenyns under the name of Alosa pectinata. This species is readily
