Localities. — Table Cape (R. M. Johnston); lower beds at Muddy 

 Oreek. 



Authentic specimens of this species I have not seen, but the 

 shell which I have figured under the name agrees with the diag- 

 nosis and dimensions given of the type. 



23. Voluta costellifera, spec. nov. Plate ii., fig. 8. 

 This species differs from V. lirata by its shorter spire, more 

 ventricose body whorl, and stronger ribs. 



Dimensions. — Leng-th, 61; breadth, 29; length of aperture, -17. 

 Locality. — Lower beds at Muddy Creek. 



24. Voluta pseudo-lirata, Tate. 

 Reference. — Gastropods, Part L, plate xiii., fig. 6. 



Shell fusiformly cylindrical, rather thin. Pullus dome-shaped 

 of two smooth whorls. 



Whorls five, excluding the pullus, slightly convex or sub- 

 angulated medially; posterior whorl ornamented with slender, 

 angular, crowded costse, which become fewer and stouter with the 

 increasing revolution of the spire, there being 14 on the last 

 whorl. 



Last whorl hardly tapering to the broadish front; aperture 

 elliptical, not much longer than the spire ; outer lip thin, slightly 

 curved medially, patulous at the front ; canal short, broad, open, 

 a little bent to the right and reverted. Columella nearly straight, 

 with four oblique plaits, the anterior one the smallest. 



Dimensions. — Length, 62; breadth, 19; leng-th of aperture, 

 35 ; diameter of pullus, 5. 



Localities.— Jjower beds at Mudd^^ Creek ; blue clays at 

 Schnapper Point. 



This species has the general character of V. lirata, but difiers 

 in shape and in the well-developed costse ; being somewhat inter- 

 mediate between that species and V. sarissa., though differing 

 from the latter by its pullus and the absence of sjDiral sculjDture. 



25. Voluta cathedralis, Tate. 

 Reference. — Gastropods, Part L, plate xiii., fig. 10. 



Shell fusiformly cylindrical ; pullus dome-shajDed of two and a 

 balf smooth whorls. Whorls four and a half, excluding the jduIIus ; 

 the two posterior whorls nearly flat, spirally lined ; the rest of 

 the whorls very slightly convex and tuberculated in the middle 

 line, the posterior slope spirally lined, the anterior slope smooth ; 

 there are about 10 small transverse wedge-shaped tubercles on 

 the penultimate whorl. 



Last whorl narrow-oblong, tubercles about seven, the last one- 

 third plain ; transversely striated all over and spirally striated 

 next to the suture. Aperture elliptical ; outer lip thin, nearly
