TEBEBRA MARTINI, n. sp. 

 Plate 23, figure 3 



Shell small, spire high, conical whorls eight or more; ornamented 

 by twenty-five prominent longitudinal ridges which are slightly con- 

 cave towards the mouth opening ; suture impressed, distinct sutural 

 hand below suture bounded anteriorly by a pseudo-suture, band equal 

 in width to one-sixth height of whorl. 



This species has narrower sutural band and more numerous ribs 

 than T. cooperi Anderson, from the Temblor formation. It has nar- 

 rower sutural band, and more numerous and much more prominent 

 vertical ribs than Terebra simplex Carpenter. 



Altitude (spire broken), 15 mm.; width, 5 mm.

CANCELLARIA ELSMERENSIS, n. sp. 

 Plate 23, figure 8 



Shell fusiform, spire elevated, whorls five to six; whorl^ of spire 

 angulated, angulation absent on the body whorl; mouth opening oval; 

 whorls ornamented by ten to twelve longitudinal ridges; on body whorl 

 these ridges become low and irregular in shape; whorls show three or 

 four faint spiral lines which are absent from the body whorl except 

 for small area on posterior part of columella; outer lip thin; columella 

 encrusted, smooth except for two acute plications anteriorly ; callus 

 extends above suture; canal short, straight. 



This species is similar to C. cooperi Gabb, from which it differs by 

 its smaller size, absence of angulation on body whorl, and the irregular 

 ridges and growth lines on body whorl. 



Altitude, 25 mm. ; width, 12 mm. ; mouth opening width, 5 mm., 

 equal in length to half total height of shell.

TURRIS ELSMERENSIS, n. sp. 

 Plate 23, figures ±a and 46 



Shell small, fusiform, spire high, apex unknown, whorls four to 

 five present ; angulated near suture, concave slope above shoulder ; 

 whorls slightly convex below shoulder; body whorl evenly convex; 

 longitudinal sculpture consists of eleven to twelve prominent rounded
