being intermediate between that figured by Morse (figs 
10 and 11) for Lingula sp. from Nagasaki, Japan, and that 
for L. anatina. 
Mr. Hedley sent us a small specimen collected at Fyfe 
Bay near the south-eastern corner of British New Guinea 
(Lat. 10° 35’8., Long. 150° E.) and recorded by him as J.. 
anatina (1898, p. 369). It measured 34 by 14.5 mm. (ratio 
2.34) and had a small peduncle 28 mm. long. The shell 
characters were those of a young L. exusta. 
As already mentioned when dealing with L. hians, 
Tapparone Canefri identified an Australian specimen sent 
by Dr. Cox under the name of L. murphit as being L. 
exusta, but we believe it to have been L. hians. 
Lingula bancrofti n.sp. 
(Text-figures 1-7; pl. I, figs. 1-4). 
Representatives of this new species were collected by 
Dr. T. L. Bancroft and Miss M. J. Bancroft in December, 
1916-January, 1917, at Burnett Head. They obtained 
their specimens by digging a large hole in the wet sand 
and then picking out Lingula, Thalassema and other 
invertebrates as the sides of the excavation fellin. By this 
means several very small brachiopods were gathered. We 
subsequently visited the locality on different occasions 
during 1918 and obtained additional material. Two dead 
Lingulas collected by Miss G. James on Pialba beach to 
the southward, belonged to the same species. No doubt 
L. bancrofti will be found to occur on many of the same mud 
flats on the shores of Hervey Bay, of which Burnett Head 
constitutes one boundary.* 
This Lingula was met with at the Head in a portion of 
a bay-like area, exposed at low tides, and partly enclosed 
by the breakwater on the southern side of the entrance to 
the Burnett River. Its presence was detected by the 
occurrence of slit-like apertures in the mud from about 
ten yards from high water mark down to the furthermost 
limit of low tide. The animal appeared to be sociai in habit. 
It is worthy of note that the mud-inhabiting crabs were 
*Miss James has forwarded others collected at Torquay and Urangan, 
on the coast of Hervey Bay (June, 1919).
