with interest. Several teeth of Chimeroid fishes pertain to Ischyodus, 
among which may be recognized the Middle and Upper Jurassic 
species I. Egertoni; and some very fine examples of tooth-bearing 
jaws indicate the presence of a Pycnodont Ganoid, probably Gyrodus. 
A tooth of Ptychodus from the Middle Chalk of Hast Lutton seems 
to be referable to P. rugosus; and the common Cretaceous Shark, 
Lamna appendiculata, is represented by a tooth from the Lower 
Chalk of Wharram Grange. 
Acquisitions of all kinds are continually being made, chiefly 
through the researches of the Honorary Curator, Mr. Chadwick ; and 
much that is novel and interesting is being met with in nearly all 
departments.

(1889, London, Triébner & Co.) 
URING the past eight years, a very valuable series of Catalogues 
have been published, under the authority of the Trustees, 
descriptive of various portions of the fine Collection of fossil 
organisms preserved in our great National Museum of Natural 
History. One of the latest of these, by Mr. A. H. Foord, issued in 
January last, gives us the first instalment of what cannot fail to be 
a most acceptable contribution to our knowledge of the testaceous 
remains of that ancient group, the Cephalopoda, which in Scandi- 
navia, Bohemia, and elsewhere, often form entire beds of limestone 
with their many-chambered shells. 
So much having been published of late years both in Europe and 
America upon the Cephalopoda, it became extremely desirable to 
have a Catalogue of our own National Collection, in order that we 
might know how far it could be deemed to be a fairly-complete 
representation of what must certainly be looked upon as the highest, 
and also the most interesting class of the Mollusca. 
If we may form a criterion of the whole collection from the 
present Catalogue, which embraces seven families only, namely, 
the Orthoceratidee, the Endoceratide, the Actinoceratid, the Gom- 
phoceratide, the Ascoceratide, the Poterioceratide, and the Cyrto- 
ceratidee, which are only a part of the suborder Nautiloidea, we 
have a right to conclude that the Cephalopoda are remarkably well 
represented in the Geological Department, and that this Catalogue, 
when completed, will be one of the best of its kind ever produced. 
Under each genus, the generic characters are carefully given, and 
similarly under each species the synonymy and references, the 
specific characters, with the horizon and locality of each, and 
remarks upon the specimens described. In fifty-one instances the 
species are figured as woodcuts in the text carefully drawn with the 
author’s own hand.
