flat; the lower carina becomes more prominent on T. lompocensis on 

 the later whorls whereas the reverse is true on the other; the two 

 sets of spiral threads on either side of the suture appear to be 

 absent on T. lompocensis. 



Named in honor of Dr. John P. Buwalda. 



Dimensions: — Length of medium-sized specimen, 20 mm.; di- 

 ameter, 6 mm. 



Occurrence : — University of California Locality 672 in white sand- 

 stone of the Tejon group just beneath the overlying diatomaceous 

 shale. 



TURRITELLA KEWI, n. sp. 

 Plate 42, figure 8 



Shell long, slender; whorls probably about thirteen or fourteen 

 in number ; each flat-sided whorl is decorated by five spiral lines 

 with a single fine thread in the interspace. The spiral lines consist 

 of two sets, an upper one near the suture of three closely set lines 

 and a lower of two lines which are relatively widely separated. The 

 suture linear, impressed, slightly below the surface of the flat-sided 

 whorls. Mouth, quadrate. 



This species is distinguished from T. buwaldana, n. sp. by a dif- 

 ferent suture, by a great apical angle and by its decoration. It 

 occurs with T. uvasana and with T. binvalelana at University of 

 California Locality 672. 



Named in honor of Mr. William Kew. 



Occurrence: — University of California Locality 672, Tejon of 

 Fresno County, California. 



Dimensions: — Length of broken type, 22 mm.; width of body- 

 whorl, 8 mm. 



TURRITELLA ANDERSONI, n. sp. 

 Plate 42, figures 9a, 9b 



Shell very elongate with about sixteen whorls which increase 

 but slightly in size. The sides of the whorls are flat and in the 

 type are decorated by minute obscure spiral threads crossed by 

 small sinous growth lines. Suture impressed, linear. 



This species differs from T. uvasana Conrad in shape of whorls, 

 in lack of strongly marked ribbing and in having a smaller apical 

 angle. 



It differs from T. pachecoensis Stanton with which it has been
