QUEENSLAND MOLLUSC AN NOTES, No. S. 75 
Prophetilora arizsla gen. & sp. nov. 
(Plate IX, figs. 10, 11.) 
A toothless “ Lucinid” with delicate concentric sculpture and somewhat 
indistinct radials, which can be easily visualised as being like a large 
embodiment of the shell described as Lucina ramsayi by Smith (Rep. Chalk 
Zool., vol. xiii, 1885, p. 174), for which I have recently introduced (Rec. Austr. 
Mus., vol. xvii, 1930, p. 390) the genus name Monitilora. In the present case 
the cardinal is missing, the lunule still more impressed, and the interior inside 
the pallial line chalky and pustulose. 
Shell semi-circular, subglobose, subequilateral, equivalve, um bones small, 
attingent. Colour white, somewhat glassy, translucent, thin but strong. Lunule 
small but deeply impressed, anterior side somewhat pointed, posterior side 
subangulate. The sculpture consists of fine concentric well-marked lirse obscurely 
striate with fine radials which form a subcrenulation only discernible with a 
glass. An indistinct radial groove marks off the posterior wing. Interior 
chalky inside the pallial line, vitreous outside. Hinge edentulous. Muscle scars 
normally lucinid, rather narrow and elongate. 
Length 38 mm. ; height 34-5 mm. ; depth of single valve 10 mm. 
Habitat : North Queensland. Type from Friday Island, Torres Strait. 
Also collected at Michaelmas Cay. 
Fallartemis amina gen. & sp. nov. 
(Plate IX, figs. 14, 15.) 
Mr. Melbourne Ward brought back a large quantity of shells and shell- 
sand from the beach at Friday Island, Torres Strait, and many Dosinids were 
present. Two very distinct forms are here named ; the commonest species in 
the collection being Dosinia deshayesii which was well figured by Smith (Rep. 
Chalk Zook, vol. xiii, 1885, pi. i, fig. 1). The present genus is based on a 
comparatively smooth shell of the sculjrta Hanley series which is here named 
Fallartemis amina, and is named as type of the genus, there being a number 
of species related to sculpta. 
Shell small, subcircular, thin but strong, broader than high, fairly 
compressed, lunule small, rather shallow, escutcheon obsolete. Colour white, 
with faint radial underlying translucent streaks, more noticeable medially. The 
sculpture consists of fine lamella: set very closely, and comparatively smooth 
medially ; they develop on each edge into fine frilled puckers more pronounced. 
At each side radials also appear, these being most marked on the anterior 
side, and missing on the medial portion that appears smooth and rather shining. 
Hinge line shallow', more spread than in Pardosinia, the adductor muscle scars 
rather small and narrow. Pallial sinus of median length, reaching about half- 
way across both as to height and breadth. 
Height 29 mm. ; length 32 mm. ; depth of single valve 8 mm.
