New Species of Victorian Mollusca. 101 



Locality. — Dredged alive by Mr. C. J. Gabriel from about 

 five fathoms, on a muddy bottom, off Phillip Island, AVestern 

 Port. 



Observations. — This new species is closely allied to some of our 

 undescribed fossil forms of Eocene and Miocene age, but can be 

 readily distinguished upon close examination of the material 

 hitherto examined. 



Drillia howitti, sp. nov. 



Shell thick and strong, elongately turreted, with a spire about 

 two and a half times the length of the aperture, and consisting of 

 a smooth convex translucent embroyo of about one and a half 

 whorls, succeeded by about seven, gradually increasing nodose 

 whorls. 



Apex obtuse, whorls very slightly convex, with a well-marked 

 suture, and a broad flat or very slightly convex area below the 

 suture occupying a little less than half the breadth of the whorls. 

 Below the sutural band the whorls are more markedly convex 

 owing to the presence of smooth oblique nodosities, which number 

 from about ten to thirteen or fourteen to the whorl, usually with 

 thirteen on the penultimate whorl. 



The shell is otherwise smooth showing the lines of growth only 

 very faintly. 



Aperture narrow-ovate, with a broad shallow sinus fully 

 occupying the flat area below the suture ; the breadth of the 

 sinus being somewhat detracted from by the presence of a large 

 and prominent tubercle on the columellar side. Columella white 

 and slightly twisted. Anterior canal very short, but relatively 

 rather broad. Outer lip thin at the margin and smooth within. 



Colour, white, creamy, or light brown. 



Diinefisions. — Length, 13 mm.; breadth, 4 mm.; length of 

 aperture, 5 mm.; breadth of aperture, 2 mm. 



Locality. — Gippsland coast. 



Observations. — The name is given to tlie species as a compli- 

 ment to Mr. A. W. Howitt, F.G.S., who has added so much to 

 our scientific knowledge of the Gippsland area. This species is 

 quite distinct from any described forms with which we are 

 acquainted, but in many respects it is closely allied to some 

 undescribed species from Victorian deposits of Miocene age.
