218 DR. T. DAVIDSON ON EECENT BRACHIOPOD A.. 



frontal margius. Peduucle longer than the length of the shell, dark in colour. Length 

 of shell 1 inch 7 lines, breadth 8 lines. 



Hab. Moreton Bay, Australia (Strange). 



To his description of this shell Mr. Lovell Reeve adds : — " If L. MurpUiana be an 

 Australian form of L. anatina, this might be regarded as the representative in the same 

 locality of L. Jdans. Both species exhibit a peculiar coppery redness, heightened in 

 this to a dark, shining, swarthy tone of colour." I, however, believe both L. anatina 

 and L. Murphiaua to be distinct species, as Hancock found the animal to be different. 



Obs. I have seen a number of specimens of this shell, and all presented the same 

 shape and marked dark colour.

Shell elongated oval, broadest near the beaks, tapering gently to near the front margin, 

 which is gently rounded outwardly. Beaks obtusely angular ; valves very moderately 

 convex, surface marked with slight, almost microscopic, and close-set longitudinal lines, 

 the valves being likewise crossed by concentric lines of growth. Colour tan or warm 

 light yellowish brown. Peduncle about four times the length of the valve. Length of 

 shell 1 inch 4 lines, breadth 8 lines, depth 3. 



Hab. Mososeki, Japan, 7 fathoms, mud (Adams) ; Japanese Avaters (Belcher). 



Obs. Adams briefly described, but did not figure, his species ; this was done some 

 years later by myself from Adams's type in the Proceedings of the Zool. Soc. for 1871. 

 Since that period I have obtained a much larger and better specimen from Sir E. 

 Belcher, dredged by him in Japanese waters. The specimen was in s]3irits, and its 

 peduncle showed its full length. 



In 1871 I referred Adams's species to the Lingula Dumortieri of Nyst (Coquilles et 

 Polypes Eossiles de la Belgique, p. 837, pi. xxxiv. fig. 4, 1843), and I believe I did not err 

 in so doing ; but as some malacologists seem uncertain about the matter, I have thought 

 it preferable, at any rate until a large number of specimens have been collected 

 and compared, to retain the name given to the shell by Mr. Adams. 



Dr. Gwyn Jeffreys wrote me in 1871, that the Japanese shell could not be dis- 

 tinguished in any way from that of Lingula Dumortieri from the Coralline Crag of 

 Suffolk and of Belgium.
