134 RECORDS OF THE AUSTRALIAN MUSEUM. 



Among Australian collectors tliere has been a tendency to 

 confuse L. icterica with L. assimilis. Thus "J'enison Woods' 

 remarks on L. icterica^ seem to refer to L. assimilis. Smith 

 compares Lucina jacksoniensis to L. parvula, Gould^ also a Port 

 Jackson species. But Pilsbry states'^ that Gould's species does 

 not differ from L. pisidium, Dunker. In this case Bunker's 

 name must take precedence.'* 



ROCHEFORTIA EXCELLENS, Sp. nov. 



(Plate xL, figs. 5, 6, 7, 8). 



Shell unusually large, oblong, twice as long as high, rather 

 inflated, glossy, thin, translucent. Anterior side slightly longer 

 Ends rounded, dorsal margin arcuate. Ventral margin apparently 

 straight, but on rigid examination a slight median insinuation is 

 perceptible. Sculpture : external surface delicately concentrically 

 striate. Under high magnification the dorsal area is finely 

 shagreened and faint radial lines appear towards the median 

 ventral margin. Inner ventral margin slightly finely crenulated. 

 Inner part of pallial impression fimbriated. Length, 25 ; height,. 

 13-5 ; depth of single valve, 4 mm. 



This, one of the giants of its tribe, is readily distinguishable 

 by size and shape. 



Hab. — I gathered several specimens on the beach at Green 

 Island, Queensland. I also found a single valve on the beach at- 

 Suva, Fiji.

A new genus is here founded for a supposed bivalve with a spiral 

 tip, in which neither cardinal nor lateral teeth, neither resilium, 

 chondroi)hore, nor ligament, neither lunule nor escutcheon,
