grooves occur on the two topmost whorls and there cease, the rest 

 of the shell is faintly and irregularly ribbed by arcuate growth 

 lines; from the aperture to the apex and upon the opposite side 

 of the shell a series of strong cord-like varices project and mount 

 the shell perpendicularly. The end of the penultimate varix is 

 thrust into the aperture. The suture is impressed and ragged 

 from the irregular longitudinal sculpture. Aperture ovate-oblong, 

 above solute, subangled and channelled; beneath rounded. Outer 

 lip sharp, curving forward anteriorly; columella long and very 

 straight, above narrow and appressed to the body whorl, beneath 

 broadened and reflected. Umbilicus a narrow triangular deep 

 pit, walled in by the reflected columella, the penultimate and 

 incipient varices. Length 5, breadth 2 mm. 



Hob. — Little Coogee Bay, near Sydney; in shell sand. I am 

 indebted to Mr. J. Brazier for a specimen which he collected in 

 July, 1895. 



Type to be presented to the Australian Museum. 



My illustrations show the shell seen in front, the apex from 

 behind, and the base, with varix in profile, from beneath, all 

 enlarged. 



This genus appears to link the bizarre form Hoplopteron 

 (Fischer, Journ. de Conch, xxiv., 1876, p. 232) to the more 

 normal Eulimidce. The difference between the varices of Menon 

 and of Hoplopteron is rather one of degree than one of kind. 

 Indistinct varices occur in Eulima proper. On a specimen of E. 

 tessellata, Sowerby, I find a series of inconspicuous varices on the 

 upper whorls. 



The apex described above is likely to prove a plug formed in 

 life before the loss of the apical whorls.

Shell dextral, very tall and slender, gently tapering, -varies a 

 little in proportion. Whorls thirteen, gradually increasing, 

 rounded, contracted at the sutures. Colour varying from deep
