Fares KIErRuULF of Kristiania has kindly presented to the 
Geological Museum of the University of Lund a large piece of 
a fine grained, greenish sandstone, containing several specimens 
of an Inoceramus, and, for closer examination, he has placed in 
my hands a larger and more complete specimen of the same 
form. This sandstone with Inoceramus has been found by M. 
LUMH0LZ at Tambo, Queensland, and as I have not found that 
locality quoted in the literature these fossils may be of a spe- 
cial interest. Probably this Inoceramus ought to be referred 
to one of the species already deseribed from Queensland, but 
the specimens found by M. LUMHO0LZ are so much more com- 
plete and better preserved than those hitherto figured that the 
knowledge of these forms is considerably augmented by them. 
Though I have had at my disposal about 10 specimens, 
only two of them are nearly complete and sufficiently well pre- 
served, but as all of them, even the more incomplete, agree 
in all the essential characters, I refer all the specimens to one 
single species. 
The largest specimen, a cast with only a few fragments 
of the prismatic shell-layer, presents the following characters. 
Obliquely oval, greatest length 31 cent., breadth 20 cent., 
hinge margin straight, about 14 cent., continuing as a curved 
line without angle in the posterior margin. The right valve 
slightly more convex than the left one. "The shell deepest 
near the beaks, about 8 cent., abruptly tapering towards the 
beaks and the hinge margin; the angle formed by the valves 
being there a very obtuse one; at the posterior margin about 
60”, at the anterior margin about 30; this sharp angle of 
the anterior margin seems to be a very characteristic feature 
(fig. 2). The contours of the shell are regularly rounded not 
expanded at the palleal part. The beaks slightly or not pro-
