Marshall. — The Wangaloa Beds. 451 



The following list represents the results that have been obtained up to 

 the present time, but it is certain that many additions will yet be made 

 as the result of further collecting. It is, however, unfortunately the fact 

 that it is hard to extract the fossils in a satisfactory state of preservation 

 from the resistant matrix in which they are embedded : Nucleopsis major

Scala (Epitonium) parvicostata n. sp. (Plate XXXIV, fig. 3.) 



Shell of moderate size, 20 mm. by 7 mm., elongated and turreted. 

 Sculpture consisting of numerous low axial ribs extending from suture to 

 suture in each whorl. About 22 axial ribs in each whorl : these are crossed 

 by about 20 spiral striae : these striae are continued on the base. Spire 

 elongated ; 5 whorls only showing in the specimen ; whorls convex and 

 suture deeply impressed. Aperture suborbicular. Umbilicus covered with 

 a growth of the peristome. 



One specimen only, in a moderate condition of preservation. Type in 

 the Otago Museum. 



This specimen was doubtfully classed by Suter as Bittium. 



Scala (Epitonium) simplex n. sp. (Plate XXXIV, figs. 1, 2.) 



Shell small, 12 mm. by 4 mm., turreted. Sculpture consisting of nume- 

 rous broad rounded axial ribs : these are continuous over the whorls, and 

 there are about 18 on each whorl. Spiral lines about 5 on each whorl, 

 crossing the costae and interstices without interruption ; the spiral lines 

 are much more numerous on the body-whorl. Spire of 7 whorls, each whorl 

 strongly convex. Suture deeply impressed. Aperture suborbicular ; peri- 

 stome thick on the inner lip. Protoconch of 3 smooth whorls. 



This species was provisionally classed by Suter as Cerithiopsis, but more 

 perfect specimens showing the aperture cause me to place it here. 

 The genus extends from the Jurassic to the present day. 



Struthiolaria minor n. sp. (Plate XXXIV, figs. 12, 13.) 



Shell small, 18 mm. by 10 mm., oblong in shape with a subtruncate 

 base. Sculpture consisting of vertical costae and spiral grooves. Costae 

 16 in each whorl, extending almost from suture to suture, and bent slightly
