Genus EGLISIA, Gray. 



[Syn. Brit. Mus. 1840, p. 147 ; id. 1842, p. 61 (list names) ; Proc. Zool. Soc. 

 1847, p. 155.] 



Shell imperforate, solid ; whorls numerous, rounded, spirally- 

 grooved or lineated, frequently having scalariform longitudinal 

 ■varices ; aperture small, orbicular ; coluraellar margin curved, 

 thickened, flattened and angulate in front ; umbilical region 

 occupied by a twisted funiculus. 



Type. — Turho suturalis, Gray.

 1892. Scalaria triplicata, Tate, id. supp. pi. ix. fig. 2. 



Shell solid, turreted ; whorls to the number of fourteen or 

 fifteen, spirally bicarinate in the earlier stages of growth, but 

 becoming markedly tricarinate as the ephebic stage is approached ; 

 these carinae are rounded and equidistant, and are interrupted by 

 the crossing of longitudinal scalariform plates ; the front of the 

 body-whorl is flattened, spirally lineated, and crossed by lineations 

 radiating from the pillar; aperture small, rounded, angulate 

 anteriorly ; inner margin reflected ; columella slightly twisted. 



The general aspect of this shell is rather that of MathiUia, 

 Semper. Neither of the examples in the Museum collection have 

 the protoconch preserved, but it would appear from Professor 

 Tate's description {op. cit.) of the ' apex,' which he remarks is 

 ' acute,' that the protoconch is not heterostroph, so that the 

 species cannot be included in Mathildia. 



Dimensions. — Length 38 mm.; breadth 10 mm.; length of 

 aperture 6 mm. 



Form, and Loc. — Miocene : Muddy Creek, Victoria.
