developed plaits, and a small posterior one. Surface sculptured 

 .as in V. limbata. 



Dimensions. — Length, 44; breadth 21 ; length of aperture, 35. 



Locality. — Lower beds at Muddy Creek {R.T.) 



11. Voluta ancilloides, s/>ec. nov. Plate iii., fig. 7. 



Shell fusiformly oval-oblong, with a moderately elevated spire 

 •of four slightly convex whorls ending in a rather large sub-globose 

 pullus of one and a half turns, the extreme tip of which is sub- 

 laterally immersed. Posterior whorls sculptured with spiral fine 

 threads and stria?, and rather close-set slender striae of growth. 



Body-whorl hardly narrowed at the base. Aperture narrowly 

 •oblong, narrowed above, broad at the front ; outer lip nearly 

 parallel with the axis, slightly thickened ; pillar slightly incurved 

 to the broad siphonal notch ; columella with three prominent, 

 rather approximate, narrow, moderately oblique plaits. 



Dimensions. — Length, 75; breadth, 28; length of aperture, 47 ; 

 diameter of pullus, 8 ; height, 6. 



Localities. — Calciferous sandstone, River Murray cliffs near 

 Morgan {R.T.) ; lower beds at Muddy Creek [R.T.) ; blue clays 

 at Schnapper Point (R.T.) ; Table Cape {Hobart Mus.!). 



This species has the general appearance of the young 

 F. macrojotera, but the pullus is different, and the outer lip is not 

 iircuate as in that shell.

Shell lanceolate-ovate, thin; whorls smooth, shining, striate 

 with growth lines, slightly convex, but not regularly so, being 

 slightly ventricose at the anterior suture and a little depressed 

 towards the posterior one. Pullus small, blunt, smooth, papillary ; 

 the tip central, depressed, but not immersed. Columella plaits, 

 four, thin, elevated, the posterior one small ; outer lip thin, but 

 perceptibly thickened. 



Dimensions. — Length, 40; breadth, 16; length of aperture, 25. 



Localities. — Table Cape {T. Woods), common in the lower beds 

 at Muddy Creek and in the blue clays at Schnapper Point (R. T.). 



13. Voluta protorhysa, sj>ec. nov. Plate ii., figs. 6a— b. 

 Shell narrowly lanceolate-ovate, thin, with a small, low, 

 depressed, blunt pullus. Whorls six and a half excluding pullus ; 

 the three and a half posterior ones longitudinally costated ; the 

 <30st£e on the first one and a half turns are slender, angular, and 

 numerous ; on the next turn they are stouter, few, and tuber- 

 culately enlarged in the posterior-third ; and on the last half-turn
