Mount Lebanon.! The Ginglymodi are represented in Europe solely 
by fragments of Lepidosteus from the Kocene and Oligocene ; but 
two extinct genera are recorded from the Lower Tertiary of the 
United States. 
In the order “‘ Amiadz”’ are arranged the three families of Micro- 
lepidoti, Cyclolepidoti, and Halecomorphi; while Leptolepis and 
Thrissops are treated later under the Teleostei. The first family 
includes Pachycormus, Hypsocormus, Sauropsis, Agassizia, and less- 
known genera. Of the Cyclolepidoti, the typical genus, Caturus, is 
treated at length, with several figures; Thlattodus, Owen, is pro- 
visionally identified with Strobilodus; interesting figures of the 
vertebrae of Hurycormus and Callopterus are inserted ; and the section 
concludes with Oligopleurus, Oenoscopus, Macrorhipis, and Aethalion. 
The Halecomorphi comprise the extinct Megalurus; and the so-called 
Cyclurus, of the European Tertiaries, is identified with the existing 
Amia. 
The order “ Pycnodontide ” is not subdivided into families, and 
concludes the Ganoidei, with the exception of a brief appendix upon 
the problematical Dorypterus. A new figure of the head of Gyrodus 
is important, and several interesting details are illustrated in 
separate woodcuts. Cleithrolepis is placed with hesitation after 
Gyrodus, and has recently proved to be a Dapedioid.? A detailed 
description of Microdon follows, with five figures. Cwlodus is made 
to include most of the so-called species of Pycnodus and Gyrodus 
from the Cretaceous; and the genus Pycnodus proper is confined to 
the Eocene. 
A new and much improved figure of Dorypterus is given; but 
further specimens are still required before its systematic position 
can be determined. CSW

The Secretaries read the Reports of the Council and of the Library 
and Museum Committee for the year 1888. ‘The Council stated that 
they had once more to congratulate the Fellows upon the prosperous 
state of the Society’s affairs, although, from various circumstances, 
there was a considerable falling off in the total number of Fellows. 
The number elected during the year was 68, and the total accession 
54; but owing partly to the results of an inquiry into the list of 
Fellows whose addresses were unknown, and partly to greater strict- 
ness in the application of the Bye-Laws relating to the non-payment 
of subscriptions, the total loss on the year was much greater than 
usual, amounting to 97, and thus producing an actual decrease of 43
