Stylifer petterdi, Tate and May. 



Tate & May, Trans. R. Soc. S. Aust. xxiv., 1900, p. 96; S. 

 robusta, Petterd, Journ. of Conchology, iv., 1884, p. 140; non 

 Pease, 1860. 



(Fig. 27.) 

 Under the name of Stilifer tumida, Petterd, 

 Mr. Brazier exhibited to this Society, August 

 29th, 1894, a shell from the neighbourhood of 

 Wollongong, N. S. Wales. This name has, I 

 believe, not been published by Petterd. The 

 Wollongong shell which I have lately examined 

 is certainly S. robusta, Petterd. As the species 

 has never been illustrated, I now present a 

 drawing of a Tasmanian example kindly lent 

 Fig. 27. me for the purpose by Miss Lodder. 



Endodonta concinna, n.sp. 



(Plate xlviii., figs. 1-3.) 



Shell minute, thin, subdiscoidal, spire scarcely elevated, 

 umbilicus broad and deep. Colour pale yellow, faintly and 

 obscurely mottled with brown. Whorls four, rounded, excavated 

 at the suture and a little flattened at the base. The first half 

 whorl is tilted from the plane of adult growth. Umbilical crater 

 a third of the diameter of the shell, exposing previous whorls, 

 umbilical suture deeply enfolded. Sculpture: no spirals exist; 

 the first half whorl is bare of radial sculpture, which commences 

 abruptly as fine, sharp, raised hair fines, about twice their 

 diameter apart, sinuate at the suture as usual in the group; 

 of these I count 98 on the last whorl; their interstices have a few 

 very fine lines, parallel to the main sculpture. Height, -56; 

 major diameter, 1-48; minor, 1-24 mm. 



Hob. — Bundaberg, Queensland; collected by Dr. T. H. May. 



Type to be preserved in the Australian Museum.
