IGO 



Ordinary whorls flat, separated by a slightly excavated suture,, 

 and having a linear spiral sulcus at the posterior-fourth ; orna- 

 mented with transverse curvilinear flat ridges or wrinkles, and a 

 few spiral flat threads medially and linear grooves near the 

 anterior suture ; the spiral ornament is only conspicuously 

 developed on the anterior whorls of larger examples. The first 

 five spire-whorls faintly costated. 



Dimensions of figured specimen of 2-") whorls : — Length, 47 ; 

 width of last whorl, 6. The largest examples attain to 60 mills, 

 in length. 



Locality. — Lower beds at Muddy Creek. 



This is very distinct from any living species. 



2. Terebra catenifera, Taic. Plate viii., fig. 14. 



Reference. — Southern Science Record, January, 1886, p. 5. 



Shell pyramidal, elongate, of many polished whorls, ending in 

 a papillary pullus of two rather large, smooth, convex turns. 



Whorls convexly flattened, slightly overlapping ; double banded 

 and nodulose in front of the suture, the posterior band rather the 

 broader, and separated by a shallow sulcus, in the centre of which 

 winds a subangular ridge defined by linear grooves ; about twenty 

 pairs of nodulations on the penultimate whorl ; anterior half of 

 each wdiorl distantly and superficially spirally ridged ; the whole 

 surface arcuately striated by lines of growth ; base spirally ridged 

 and transversely wrinkled. 



Dimensions. — Length of 17 whorls, 38; breadth of last whorl, 7. 



Locality. — A common fossil in the upper beds at Muddy Creek. 



It lias much resemblance to the Japanese species, T. serotina.j 

 Adams & Reeve. 



3. Terebra subcatenifera, spec, nov.* 

 Shell similar to T. catenifera, but the double row of nodula- 

 tions, which are very much larger, are separated by a linear 

 furrow ; the anterior half of each wdiorl is sculptured with four 

 equidistant spiral grooves separated by much wider flat ridges ; a 

 more or less distinct transverse angular ridge is clecurrent from 

 each tubercle of the anterior row to the anterior suture. 



Dimensions. — Length of 15 whorls, 25; width of last whorl, 5-5. 

 Localities. — Cunninghame and Jemmy's Point, Gippsland 

 (W. H. Gregsonf). 



4. Terebra niitrellaeformis, Ti7h\ Plate ix., fig. 10. 

 Reference. — Southern Science Record, January, 1886, p. 7. 

 Shell cylindrically subulate, polished; whorls convex; upper 

 whorls distinctly costated, interrupted near the suture by a
