gently on each side from the midline so that the cavity of 
the shell was comparatively deep, as in L. murphiana. 
The anterior sete were seen to be arranged in three groups 
as in L. anatina. The brownish peduncle terminated in 
a small ampullary region enclosed in a sandy tube about 5. 
mm. long. Since Tenison-Woods collected extensively in 
Northern Queensland, and seeing that all definitely known 
Australian localities for the species are in that region, it 
is quite probable that confusion in regard to localities 
has arisen. We feel justified in declining to recognise 
Port Jackson as a habitat, Prof. Haswell agreeing with 
our action in this matter. 
K. J. Banfield in his recent book “ Tropic Days ” 
1918, pp. 106-7) referred to the occurrence of a Lingula 
én Dunk Island, to the north of Rockingham Bay, North 
Queensland. ‘* In the mud close to the edge of the beach 
sand one of the most singular of marine animals exists 
and often its empty, horny, flexible semitransparent shell 
always tinted green, may be found. It is known in some 
works as Lingula anatina, and by the natives of this Isle, 
by whom a certain part is eaten, as ‘* Mill-ar-ing.’ A 
pinhole in the mud indicates the presence of the animal 
and the hungry black boy, thrusting his hand with out- 
spread fingers below it, closes the fingers and withdraws 
anything but an inviting morsel. To the tongue-shaped 
shell is attached a pedicle or stalk, attaining a length of 
ten inches, opaque and tough, which is broken off, seared 
over the fire, and eaten with apparent relish. It is remark- 
able that in localities where this mollusc is found, a seaweed 
occurs similar in shape and size, the chief difference in > 
appearance being in the length of the stalk which in the 
plant is thin and membranous.” (? Halophila ovata T.H.J.). 
The “empty horny, flexible, semitransparent shell, 
always tinted green ”’ suggested L. hians, but in answer 
to our request for specimens, Mr. Banfield kindly sent down 
a goodly number collected in a few minutes in sandy mud 
near Brammo Bay, Dunk Island. The species has been 
determined by us as L. exusta. Either L. hians occurs in 
addition, or the above remarks regarding shell characters 
relate to young specimens of JL. exusta which are rather 
difficult to distinguish from L. hians. The adults are quite
