Victorian Marine Mollusca. 3 



Cyclostpema bastowi, sp. nov. (PI. II., Figs. 8-10) 



Shell minute, discoirlal ; white. Spire sunken. Whorls four, 

 suture linear. Rather widely and perspectively umbilicated. 

 Upper surface : the periphery is roundedly carinate, and, under 

 the lens, densely ti-ansversely striate ; the carination starts from 

 the protoconch and continues to the lip ; inside of this carination 

 is a raised continuous ridge of closely compacted spirally elong- 

 ated granules. Side : bicarinate, with a flat groove between. 

 Base: cariiiated similarly to the surface; inside the carination 

 the closely compacted granules are more elongate and continue 

 down the uml>ilicus. Outer lip thin. 



Dimensions of type. — Greatest diameter, 0.9 mm.; height, 

 0.35 mm. 



Locality. — Dredged in about 9 fathoms between Phillip and 

 French Islands, Western Port. 



Observations. — This little shell shows a very decided form of 

 sculpture, and reminds one of a Solarium. I have much pleasure 

 in naming it after Mr. R. A. Bastow, who has skilfully drawn it 

 and the other .species named in this paper. 



Type in my collection. 



Tuppicula tasmanica, T. Woods. (Ph II., Figs. 6 and 7). 



Referring to vol. xviii., p. 45, of these Proceedings, it is stated 

 there that what was considered to be the typical form had not 

 been found here. Since then whilst dredging in Western Port, 

 between Phillip and Frencli Islands, in about ten fathoms, 

 Mr. C. J. Gabriel and I obtained four living and one dead shells, 

 and upon submitting one to Mr. W. L. May of Tasmania, he 

 informed me that he considered it ti> be the above species, but 

 ditlering from the type in some minor details. As it does not 

 quite agree with his figure of what he considers to be the type, a 

 figure is now given of one of those we obtained, so that it may 

 enable future collectors to identify it. The dimensions of the 

 specimen figured are : length, 13 ; breadth, 5.5 mm.
