ANNELID TEAILS.

Signs of the passage across sand or mud of animals low in the 
scale of organization are, it is well known, of frequent occurrence 
wherever the older rocks have been sedulously explored. It might 
naturally have been expected that similar rocks in Queensland 
^ould have supplied examples of such "footprints on the sands of 
time," but I am not aware that in them instances of the kind have 
hitherto been made known. If only on this account some trails 
discovered and recognised as such by Mr. Berney may have to the 
geological mind a certain amount of interest, an amount which will 
certainly not be lessened by the excellent state of preservation 
retained by them during so many ages. 
They present themselves for examination (happily unappre- 
hensive of the modern ordeal) in two forms on a few square inches 
of indurated mud, itself coming before us in " questionable shape " 
— seeing that there is a consensus of opinion that among the multi- 
farious traces of animal life, that have been attributed to the move- 
ments of the tubercular bristle feet of Annelids, some, like the 
present, are doubtless to be credited to that agency, the origin of 
those under notice may be taken for granted. Of one of them, 
indeed, a Nereites, the generic identity is beyond doubt, and, under 
the circumstances, I have no hesitation in naming it, in compliment 
to its discoverer, Nereites Berney i. This trail, the longer of two, con- 
sists of the usual double row of markings, the more perfect of them 
presenting in this case a raised semi-oval buckle-shaped border, 
enclosing a shallow impression with a minute elevation in the 
centre. The markings are 25 mm. long, set alternately at an angle 
of 45 degrees to the axis of the trail, which has no median groove ; 
four of them occupy the space of one centimetre, and the double 
row is 6 mm. broad. 
Genus. — The shorter trail was moulded by a genus unknown 
to me. It also consists of a double row, but one of close-set
