plain and the posterior wing more or less restored, but probably correctly so. 

 I suggest its identity with de Koninck's figure of I'ferinen iiKicropfern, but 

 not with Morris's bivalve of the same name. Again, it is not far removed 

 from the smaller of the two figures of Modiola crassissiuia, which, it is 

 almost needless to say is not a Modiola. 



Lor. — Harper's Hill. 



9. iCypricardia'] veneris, Dana. — Another of Dana's illustrations that 

 puzzled me for many years ; I have not a replica of this specimen, but some 

 light is, 1 think, thrown on [C] veneris hj & shell collected at Wollougong 

 by Mr. W. S. Dun (PI. xxxi., fig. 8). This is a very ti-ausversely-elongate, 

 more or less siliquiform bivalve, attenuated at the anterior ends, and 

 thence slightly expanding to the posterior. The cardinal margins are 

 more oi" less eroded but they were long, straight and apparently edentu- 

 lous. The anterior ends are peculiarly lobe-like, and obtusely pointed, 

 whilst the posterior comprise quite nine-tenths of the valves. The 

 sculpture was both concentric and radiate, the oblique radii from the 

 umbos extending over the median and posterior surfaces. Although 

 Dana's figure was evidently drawn from a poor and imperfect specimen, 

 stilJ, the same insinuated venti'al margins as existing hei'e, the tendency 

 to a siliquiform outline, and the large number of i-adii, only equalled by 

 those of Statrkhuria costata, will, I believe, uphold the accuracy of this 

 refei'euce. The generic identity of this fossil must remain open for the 

 present. 



Lor. — Glendon, Hunter River. 



There are also in the collection other Stutchburia-like shells of 

 doubtful identity, three of which may be mentioned to attract the attention 

 of collectors. 



Stutchburia, 1. In form like S. costata, Morris, but stouter, and each 

 valve traversed by three well marked radii only, from the umbos to the 

 middle of the ventral margins. 



Lac. — Wollongong, lllawaiTa District (W. S. Dun). 



Hor. — Upper Marine Series. 



Stutchburia (.'') 2. A small and oblique form with about six radii 

 occupying a similar position to those on No. 1. The concentric sculpture 

 is very regular and fine, and on crossing the radii, a coarse decussation is 

 apparent. 



Loc. and Hor. — As in No. 1. 



Stutchburia (f) 3. — Of the S. costata type in general, but pod-shaped, 

 and with the whole of the posterior two-thirds of the valve surfaces radiate, 

 the most anterior radii striking the ventral margins, at about their middle 

 points ; the first four radii are distinctly spaced apart. 



Loc. and Hor. — As in No. 1.
