University of California Locality 1853. Named in honor of 

 Mr. Storms, State Mineralogist, California State Mining Bureau, 

 who very kindly loaned vis several of Dr. Cooper's type speci- 

 mens. This species resembles Caricella pyruloides Conrad of the 

 Alabama Claiborne very closely. 



Dimensions: Length, 15mm; width of body-whorl, 6mm. 



PHOS(?) MARTINI, n.sp. 

 Plate 13, figure 5 



Shell, bucciniform with very sharp spire, whorls seven and a 

 half ; the first three smooth, minute ; fourth, fifth, and sixth 

 marked by vertical ribs crossed by three revolving riblets which 

 form a beaded structure at intersection. The vertical ribs num- 

 ber twelve on the fourth, fifteen to sixteen on the fifth, and 

 eighteen or twenty on the sixth whorl. The revolving and vertical 

 ribs are the same in strength on the body-whorl. The inner lip, 

 crenulated ; columella smooth. Canal unknown, but is probably 

 short and narrow.

CALLIOSTOMA( ?) ARNOLDI, n.sp. 

 Plate 14, figures 5a, 5b, and 5c 



Shell conical, with moderately angulated base. Whorls, num- 

 ber six the first two, turbinate. The second, third, fourth and 

 fifth whorls are marked by three nodose revolving lines while the 

 body-whorl has six, five of which are continuous on the base. A 

 part of the body-whorl is broken, making an accurate descrip- 

 tion of its base impossible. The body-whorl is about one and 

 one-half times the penultimate whorl. Aperture, subquadrate. 

 The apical angle of this species is very small in comparison with 

 many species of this genus. 



University of California Locality 1853. Named for Dr. Ralph 

 Arnold. 



Dimensions : Length, 6mm ; width of body- whorl, 3mm.
