ribs carry small dense scales. Stewart Island is the type-locality, 

 but the individual here drawn came from the Chatham Islands. 

 Ostrea radiata of Gmelin was afterwards transferred to Pecten, 

 but it does not seem to imperil the name of the present species, 



Pholas Australasia Sowerby. 



Sowerby, Thes. Conch, ii. 1849, p.488, Pl.cvi. f.73. 



Probably because it is absent in the immediate neighbourhood 

 of Sydney, this species has escaped notice in literature as native 

 to New South Wales. Nevertheless it is common, and generally 

 distributed along the whole coast.

This species has not been recorded from Australia. Mr. P. 

 G. Black gathered specimens on the beach at Townsville. My 

 determination of these was confirmed by Mr. C. Gabriel, who 

 compared Queensland specimens at the British Museum. 



Strigilla eukonia, n.sp. 



(Plate ix., figs. 22-23.) 



Shell of medium size, subrhomboidal, compressed, rather thin, 

 glossy, slightly inequilateral, ventral margin rounded, anteriorly 

 and posteriorly truncate. Colour lilac, concentrically disposed in 

 paler and darker zones. Smooth, except for the oblique scratches, 

 which number thirty-six, commence at a short distance from the 

 posterior margin, and suddenly terminate with great exactness 

 at a perpendicular median line. The scratches are closer 

 posteriorly, wider anteriorly, spreading apart from the umbo 

 outwardly. The unscratched posterior end has fine concentric 

 thread-sculpture. Length, 16; height, 14; depth of single valve 

 4 mm.
