are the measurements of the type. We have other examples 

 ranging to length, 6 mm. ; breadth, 4 mm. 



Locality. — San Remo, Western Port ; Otway coast, between 

 Ryan's Den and Moonlight Head, (Mr. P. J. Fulton). 



Observations. — Though this shell was first known to Mr. Gatliff 

 from San Remo, we have obtained many additional examples 

 through the kindness of Mr. S. W. Fulton, whose brother col- 

 lected them at the above mentioned locality. This species has 

 already been referred to under manuscript name in Part III. of 

 our catalogue of Victorian shells. The present species is a larger 

 form than Tate's Erato bimaculata, and also difiers from that 

 species in its longer spire, lower shoulder, apertural characters 

 and colour markings. We have an example, probably, represent- 

 ing this species, from St. Vincent's Gulf, South Australia, collected 

 by G. B. Pritchard ; but the South Australian shell presents 

 these characters : it is much thinner, narrower, and more translu- 

 cent, the outer lip is thinner and narrower, and the body whorl 

 shows fine striae of growth ; these features, however, are only 

 what might be expected from well grown, but still immature, 

 examples. 



Type in Mr. Gatlifi''s collection. 



Turbonilla (Ondina) micna, sp. nov. (PI. XXL, Fig, 1.) 



Shell minute, bulimoid, consisting of an apparently smooth 

 embryo of about a whorl and a half, the axis of enrolment of 

 which makes a slight angle with the axis of enrolment of the 

 shell, succeeded by three to four whorls. The embryo, magnified 

 70 diameters, shows distinctly pitted spiral grooves. 



Whorls only slightly convex, with a fairly impressed suture ; 

 the whorls are sculptured by very fine regular spiral lines, but 

 the presence of pitting along these cannot always be detected with 

 an ordinary lens, higher magnification, however, reveals their 

 presence. 



Aperture a little longer than a third the length of the shell, of 

 an elongate oval shape, and broadly rounded at the anterior end, 

 where it appears slightly eftuse. Columella twisted, inner lip 

 reflected over a slight umbilical chink. Outer lip with a 

 thin sharp edge, but thicker within, and shows a distinct
