6 BERNH. LUNDGREN, ON AN INOCERAMUS FROM QUEENSLAND. 
der and acute anterior part and a less curved anterior margin, 
thus being very unlike the species in question. ETHERIDGE 
has described and figured 4 species of Inoceramus from Queens- 
land (Quart. Journ. Geol. Soc. of London, vol. 28, 1872); un- 
fortunately the descriptions are so brief and the figures re- 
present so incomplete specimens that I must agree with ScHLU- 
TER (Kreide Bivalven; Zur Gattung Inoceramus p. 29, Palxon- 
tographica 1877) that it is impossible with certainty to identify 
any one of the figured Inoceramus fragments. I. Marathonensis 
Eth. (1 c. T. 22, f. 1) has the beaks much more produced and 
slender; I. multiplicatus Stol. var elongatus Eth. (T. 22, f. 2) 
has finer and much more numerus concentric ribs. I. pernoides 
Eth. (p. 343, T. 22, f. 3) is quadrate, has the beaks acute and 
prominent, the anterior margin excavated beneath the beaks, 
concentric ribs fine and numerous. As this name is already 
employed by GOLDFUSS, PORTLOCK and MATHERON it cannot be 
retained for the australian species. »I. allied to I. problema- 
ticus» (T. 22, f. 4) has the beak of a quite different shape than 
that of the present form. 
Although 6 species have been described from the creta- 
ceous system of Queensland, it seems me impossible with cer- 
tainty to identify the above described form with any of them, 
since they are all so very unperfectly known. Yet as this 
form may probably belong to some of them, I have for- 
born to give it a name and I will only state that it may pos- 
sibly be referred to I. Carsoni M'cor or I. pernoides Eth. (non 
GOLDFUSS etc.). 
Found at Tambo, Queensland, (about lat. 25”, long. 146” 
by the map of Andree) by M. LUMHO0LZ.
