phalus in the Warwick Museum being nearly entire, 
measuring 14ft. 4in. in length. The remains of plants, 
though small and fragmentary, are of considerable interest, 
because together with the insects, they afford the only 
evidence of the inhabitants of the land. Ferns and 
conifere are the predominating forms, but not very 
numerous. Large branching masses of drift-wood are 
sometimes met with. With respect to the insects, which 
are of special interest, twenty-four families and genera 
had been determined when my work on “ Fossil Insects ”’ 
was published more than twenty years ago, since which 
time many important additions have been made. The 
Coleoptera and Neuroptera are most numerous. Small 
beetles are not unfrequently found entire, single elytra 
are however most prevalent. Among these may be noted 
the families Buprestide, Elaterids, Carabide, and many 
others. 
There are remains of Orthoptera, Homoptera, Libel- 
lulide, and some Diptera. Many of the Neuroptera were 
evidently of gigantic proportions, but most of the Insecta 
were of small size and, like the associated plants, indicate 
a temperate climate, and are more nearly allied to forms 
which now inhabit North America. There are few extinct 
or unknown genera among them so different to the marine 
fauna associated with them. As the coleoptera were 
herbivorous, omnivorous, and predaceous, the land must 
have contained plants suitable to their food, and insecti- 
vorous animals to devour them in their turn. Although 
the Saurians and Mollusks indicate a warm climate, there 
is no proof of any ultra tropical heat, and it may there- 
fore be presumed that they inhabited the higher regions 
of a tropical country, such as the Himalayas, and were 
carried by streams into the ocean at greater or less dis- 
tances from land. With the scanty record which the
