Description

Arcopagia dapsilis: Shell small but comparatively solid, oblong-equilateral, the dorsal margins rather straight, meeting at an obtuse angle, where the umbo projects suddenly and rather obliquely; anterior, ventral, and posterior margins rounded. Colour white. The whole surface is minutely reticulated by the intersection of about one hundred fine radial threads, with concentric threads of equal size and space. In addition, there are wide elevated concentric folds, varying from none to a dozen, and which may be evenly distributed over the disk or confined to the first third or so. These coarse folds are traversed without interruption by the finer sculpture. I was unable to detect the pallial scar. Length 2,9; height 2,3; depth of single valve 0,55 mm.
This is the smallest Australian Arcopagia; its shape distinguishes it from such small forms as A. elegantissima Smith, A. tenuilamellata Smith, or A. fabrefacta Pilsbry. It seems to be widely distributed in Queensland, for not only did we take it plentifully, in 5-8 fathoms, off the Hope Islands, but I dredged it previously, in 15 fathoms, off the Palm Islands, and, in 17-20 fathoms, off Mast Head Island. Mr. H. L. Kesteven also found it on the beach at Caloundra.
