length, anterior extremity obtuse, scarcely rounded, posterior rounded 
off and rather wider than the front. End view subcircular. Surface 
smooth, cream-coloured, with transverse black bands after the 
manner of C. vidua. Length =\, of an inch. 
Hab. Condong, Tweed River, New South Wales (Mr. T. Steel).

NoToDROMAs FUSCATUS, n. sp. (Plate X. figs. 4-6.) 
Shell, seen laterally, subtriangular, height equal to three fourths 
of the length, extremities very broadly rounded, the anterior some- 
what the narrower of the two, dorsal margin excessively arched, 
highest a little behind the middle ; ventral nearly straight ; seen from 
above, the outline is ovate, scarcely twice as long as broad, tapered 
and acuminate in front, rounded off behind. Surface of the valves 
somewhat rough and furfuraceous, colour brownish, with darker 
cloudings. The ventral aspect of the shell is ribbed almost exactly 
asin N. monachus; the “ ocular”’ tubercle is large and distinct ; by 
transmitted light the shell is seen to have a polygonal reticulated 
structure, and the reticulations are visible also by reflected light on 
the anterior portion of the valves. 
Hab. At Condong, with the foregoing species. 
This is very much less tumid and less angular in outline than 
Newnhamia fenestrata, King, and its lateral outline differs in the 
same way from Notodromas monachus, Miiller.

Land, vol. iii. pt. i. p. 67 pl. x. kK. 
Male. Shell, seen from the side, subreniform, depressed in front, 
greatest height near the posterior extremity and equal to half the 
length ; anterior extremity narrow and well rounded, posterior wide, 
obliquely rounded ; dorsal margin forming a flattened arch, sloping 
with a gentle curve to the front, and abruptly backwards, ventral 
sinuated in the middle ; seen from above, compressed, ovate, about 
thrice as long as broad, gently tapered towards the front, which is 
subacuminate, rounded off behind. Shell smooth and _ polished, 
pellucid, white or straw-coloured. Length > of an inch. 
Hab. Condong, with the foregoing species. 
The shell figured in Plate VIII. figs. 10, 11, occurred in the same 
gathering, and possibly may be the young of C. lutea. 
2. CANDONA TENUIS, n. sp. (Plate X. figs. 9, 10.) 
Shell elongated, compressed, reniform ; seen from the side it is at 
least twice as long as broad, the greatest height being a little behind 
the middle, extremities rounded, dorsal margin boldly arched, ventral
