the anterior end ; upper volutions similarly decorated with nodes 

 which begin at the sutural line and become obscure just above 

 the central portion of the whorls ; surface of the shell smooth ; 

 below the nodulation of the body whorl, with the aid of the mi- 

 croscope, very fine revoling striae may be detected.

Genus PSEUDOLIVA Swainson 

 Pseudoliva soldadoensis, n. sp., PI. 3. Fig. 10. 



Description. — Size and shape of shell as indicated by the fig- 

 ures ; whorl, six, convex, with a slight shoulder ; last three volu- 

 tions of the spire, narrow and very pointed ; the shoulder of the 

 body whorl extends at about an angle of thirty degrees and 

 bears numerous small nodes. Much of the surface of the body 

 whorl of our specimen has been destroyed but on the remaining 

 portion which is about a third of the whole whorl there are 

 twelve nodes ; on the whorls of the spire a groove extends irreg- 

 ularly around the shoulder ; traces of nodes can be seen along the 

 front of this groove. The surface of the shell is otherwise 

 smooth except for lines of growth. This species is related to 

 Pseudoliva sp. that Professor Harris has figured from the Midway 

 of Alabama, pi. 9, fig. 22, Bulletins of American Paleontology, 

 vol. 1, no. 4. They both have the small nodes on the shoulder 

 of the body whorl and the upper portion of the spire, similarly 

 shaped. P. soldadoensis n. sp. is a more robust form, the upper 

 portions of the whorls are more convex and the nodes are more 

 numerous. Altitude of the shell 33 mm ; diameter 20 mm ; alti- 

 tude of spire 7mm ; angle of spire 83°
