irregular, rounded, longitudinal ribs, which vary considerably in prominence; on 

 some specimens they become obsolete on the body whorl and sometimes on the 

 penultimate whorl. Surface also covered by numerous fine, spiral ribs, the inter- 

 spaces between which vary considerably in width, being usually narrower than 

 the tops of the ribs, which also vary in width. On whorls of spire about twelve, 

 and on body whorl about twenty to twenty-three of the spiral ribs. Base of body 

 whorl regularly rounded, the spiral ribs extending down onto it. Aperture ovate 

 in outline. Outer lip thin ; inner lip incrusted. Canal short, straight but well- 

 defined. 



Dimensions. — Type specimen: height, about 20 mm.; height of body whorl, 

 about 7 mm. ; maximum width of body whorl, about 7 mm. 



Named in honor of Dr. J. C. Branner, ex-President of Leland Stanford Junior

Family Vermiculariidae 



Genus VERMICULAR! A 



VERMICULABIA '?, sp. 



At several localities in the vicinity of Kirker Creek, to the north 

 of Mount Diablo, thin lentils of blue-gray, medium fine, tuffaceous 

 sandstone are found near the top of the tuff member of the Kirker 

 formation. In this sandstone are numerous casts of small tests of 

 what appear to be Vcrmicularia ; the greatest diameter of any of these 

 is not much over a millimeter, the greatest length being about one 

 and a half centimeters.

The type of this species is reported by Gabb as coming from the 

 Miocene near Martinez ; it is possible that it came from either the 

 Monterey or the Agasoma gravidum beds. The species is reported 

 in other parts of the state as being found in the Temblor horizon. It 

 is found in the Agasoma gravidum beds at Walnut Creek, University 

 of California locality 1131, also at University of California locality 14.
