Davidson’s concise account of the shell is as follows .:— 
“ Shell large, squarish oblong, longer than wide, sides almost 
parallel, slightly curved inwards towards the middle of 
their length. Anterior edge gently rounded, with angular 
projection in the middle ; beaks attenuated, that of the 
ventral valve pointed and the longest. Valves about 
equally convex, with a flatness commencing close to the - 
beaks and extending to the front and on each side, sloping 
to the lateral edges. Colour coppery red, with bands of 
different shades of green and brown. In the interior of 
the valves, the muscular area is white, the remainder of the 
surface light and dark green. Shell structure horny and 
calcareous. Length of shell 2 inches 6 lines, breadth 1 inch 
1 line ; length of peduncle 63 inches.” 
L. murphiana is not uncommonly found in the sandy 
mud between tide marks at certain localities in Moreton 
Bay, e.g., at Sandgate (to the north of the mouth of the 
Brisbane River), and at Burpengary Creek, Deception 
Bay. 
In addition to our own material, we examined a number 
of specimens belonging to the Queensland Museum collec- 
tion, allfrom the same localities. Marten’s ZL. anatina from 
Peel Island, Moreton Bay, almost certainly belongs to this 
species which resembles L. anatina rather closely. As 
already mentioned, the brachiopods from Moreton Bay 
referred to under the latter name by Brazier (1879a) and 
Hedley (1909), and as L. rostrum by Hedley (1916), and 
Thomson (1918), belong to L. murphiana. Dall (1871, p. 
55) doubted the validity of the species stating that ‘ this 
species (?) much resembles L. anatina,’’ while in 1873 (p. 
203) he included it as a ¢synonym of the latter, but 
omitted to include Moreton Bay amongst the known 
localities. 
The length, breadth and ratio of length to breadth of 
specimens and ventral valves examined by us, were as 
follows :—59 mm. by 26, ratio 2.27 ; 59 by 26 (2.27) ; 59 by 
25.5 (2.31) ; 57 by 26 (2.19) ; 57 by 25.5 (2.23) ; 57 by 25 
(2.28); 57 by 25 (2.28); 55 by 26 (2.1); 54 by 24 (—a 
shrunken specimen—ratio 2.25); 52 by 23 (2.26); 51 by
