QUEENSLAND MOLLUSCAN NOTES, No. 1. 
265 
laterally, but never becoming much elevated, so that about one hundred may be 
counted without taking* in the umbonal stria;. Hinge broad, shallow, adductor 
muscle scars small. Pallial sinus very long, reaching nearly across and above the 
scar. Height 28 mm.; length 30 mm.; depth of single valve 7-5 mm. 
Pardosinia alma sp. nov. 
( Plate* XXX, tigs. 15, 16.) 
Another Dosinia found at Michaelmas Cay also showed peculiar coloura- 
tion resembling that of the well-known Venerids, tornima and embrittles, classed 
under Cytherea in Hedley’s Queensland list. 
Shell small, circular, solid, little compressed, lunule small, much impressed, 
escutcheon ill-defined. Colour distinctive, red-brown blotches arranged radially 
in four rows, overridden towards the margin by continuous angulate lining, 
lunule brown. Sculpture consists of regular elevated lamellae, fifty to sixty 
being counted before the umbonal smaller, more crowded, ones are reached ; these 
lrill a. little towards the edges. Hinge fairly broad and deep, adductor muscle 
scars small. Pallial sinus long and narrow, extending more than halfway 
across. Height 25 mm.; length 26 mm.; depth of single valve 9 mm. 
Bonartemis stabilis gen. & sp. nov. 
(Plate XXX, tigs. 3, 4.) 
Apparently the Dosinids have been neglected, as at Caloundra still another 
undescribed species was collected by Whitley and myself. 
Shell small, subcircular, very solid, beaks much incurved, lunule very 
deeply impressed, heart-shaped, broad, escutcheon long, well defined and 
bordered. Colour cream with brown, broad, radial splashes four in number. 
Sculpture consists of coarse but closely set lamelke, forty in number, till the 
umbones are reached, where they still exist as coarse and distant lamella; on 
each side the lamellae show a strong tendency to becoming frilled. Hinge rather 
narrow, very deep and crass, adductor scars large. Pallial sinus very short and 
angulately narrow, reaching less than halfway across. Height 29 mm. ; length 
29 mm. ; depth of single valve 10 mm. 
Heteroglypta hedleyi sp. nov. 
The name is proposed for the shell from the Nambueca River, Northern 
New South Wales, described and figured by I-Iedley under the name Asaphis 
eontraria (Proc. Linn. Soc. N.S.W., 1900, p. 731, pi. xlviii, figs. 4-8, May 20, 
1901), wdiich differs from Psammobia eontraria Deshayes (Cat. Moll. He Reunion 
p. 11, pi. 1,'f. 20-21. 1863) from the Isle of Reunion (Bourbon) in shape and 
sculpture. It does not seem to have much relationship with Asaphis . as when 
Dali so placed it (Trans. Wagner Free Inst. Science, iii, pt. v, p. 981. 1900) 
lie was autoptically unfamiliar with it. Moreover Martens had introduced the 
name Heteroglypta (Beitr. z. Meeresf. Maurit. u. Seyeh., p. 331, 1880) for it 
alone. 
At Michaelmas Cay valves of a similar shell were found, and these upon 
autoptical comparison with the southern types were seen to be also slightly 
different in sculpture and shape; the northern shell is white, more elongate, 
more inequilateral, the posterior end shortened, ventral edge less rounded,'
