A DYING LOBSTER’S FOSSIL TRACK. 
Dr. Bather, writing in Knowledge for September, describes a 
remarkable specimen recently received by the British Museum. 
It is of special interest, for the piece of limestone not only 
contains a fossil lobster, but also the tracks which it made 
when lying on an exposed mud-flat in its endeavours to get 
back to the water. The lobster evidently died while beating 
a retreat, backwards, and left its little footprints in the sands 
•of time. Dr. Bather endeavours to account for the animal’s 
death. It may have been wave-borne, or wind-swept, or 
■* even carried by some fishing form, half reptile and half 
bird . . . and dropped on a mudflat.’ Possibly the riddle may 
be solved if we read a book reviewed a few pages further on 
in Knowledge, viz., ‘ The Whole Art of Dying ’ (sic). 
COAL MEASURE PLANT CUTICLES. 
In The Geological Magazine for September is an interesting 
paper on ‘ Plant Cuticles from the Coal Measures of Britain,’ 
by Lucy Wills. The authoress refers to the methods previously 
adopted by Xathorst and others, already referred to in this 
journal, in connection with the examination of the cuticular 
structure of Mesozoic plants. In a somewhat similar way 
she deals with material from the Denbighshire and South 
Staffordshire coal measures. The cuticles are preserved as 
brown films in clayey shales, approaching fireclays in com- 
position, none having yet been found in carbonaceous or 
sandy shales. Several photo-micrographs are given in illustra- 
tion of this paper. The work described seems to be on entirely 
new lines, and the results are certainly of great value. It is to 
be hoped that it will be followed up by other students. 
A NEW YORKSHIRE TRILOBITE. 
In the same journal, Air. W. B. R. King describes a new 
trilobite from the Millstone Grit of North Yorkshire. Numbers 
of trilobites were obtained from the calcareous beds on Great 
Shunner Fell, but they are best preserved in a massive lime- 
stone bed, which is illustrated in a section given. Mr. King 
names the new specimen Grifjithides shunnerensis. He gives 
a number of figures of the species, and also some interesting 
notes on the probable former use of the ‘ pores ’ on the glabella 
of trilobites. The specimens are now in the Sedgwick Museum, 
Cambridge. 
YORKSHIRE FOSSIL FLORA. 
The Committee appointed to investigate the Jurassic 
Flora of Yorkshire, presented its report at the recent meeting 
of the British Association at Sydney. This stated that during 
the year attention had been concentrated on the plant beds
