Locality. — River Murray Cliffs, near Morgan. — Barwonian. 

 Eocene. 



Pleupotoma gpanti, sp. nov. (PI. XIX.. Fig. 3). 



Description. — Shell large, very graceful and elongate fusi- 

 form ; with a slender tapering spire less than half the total 

 length of the shell, and a long straight canal. 



Spire very acute, the general apical angle being only about 

 twenty-two or twenty-three degrees, extreme apex bluntly 

 rounded. Embryo composed of about two and a half smooth, 

 slightly convex whorls. Tlie remainder of the shell is composed 

 of nine regularly convex whorls, greatest convexity about the 

 middle of each whorl, suture impressed, but as the whorls dis- 

 tinctly overlap the greatest impression or concavity is a little 

 below the suture. Whorls spirally lirate and striate, three or 

 four threads usually being more strongly developed than the 

 rest about the middle of each whorl, seven or eight threads 

 being more thoroughly visible on the body-whorl, the remainder 

 of the surface of the shell being very finely and regularly spirally 

 striate. Transverse striae of growth, usually very faint on the 

 spire whorls, a little more distinct on the body-whorl, but dis- 

 tinctly subordinate to the spiral sculpture. Sinus broad and 

 deep, and situated in the concavity between the sutiu-e and 

 greatest convexity of the whorls, but nearer to the former. 

 Aperture elongate-oval, extending into a long, straight, and com- 

 paratively broad canal ; outer lip thin ; inner lip well defined by 

 a thin layer of enamel spread out over the columella and 

 strongly margined oft' from the spiral sculpture, the margin 

 extending down the full length of the long, straight, tapering 

 columella. 



Dimensions. — Length, 63 mm.; breadth, 13 mm.; length of 

 aperture and canal, 31 mm. ; length of aperture, about 12 mm. ; 

 breadth of aperture, about 5 mm. 



Locality. — Lower beds of Muddy Creek, near Hamilton. 

 Western Victoria. — Balcombian. — Eocene. 



Observations. — I have much pleasure in naming this graceful 

 shell after my friend, Mr. F. E. Grant, who has done a con- 

 siderable amount of work on our Tertiaries, and is always ready 

 and willing to help others in their work in any way he can.
