distinctly curved at the base, and the posterior tibiee are not 
toothed externally, but are swollen in a most remarkable 
manner just below the base and then gradually narrowed to 
the apex.

The study of Geology has been likened to geographical explora¬ 
tion, which bears small results unless the proved outcome of each 
traveller’s work is duly recorded and compared with previous addi¬ 
tions to our knowledge. It is not enough to have at hand the 
journals of travel, however carefully prepared. Comparative tables 
and indices for ready reference are necessary ; so that observations, 
past and present, far and near, may be studied together,—so that 
slips and patches of mapped lands may be combined, scattered 
descriptions of parts of nations be brought together under one 
head, and the isolated accounts of various local products be made 
to supply a compendium of the natural history of one region. 
Besides a mere cataloguing of the names of places, peoples, and 
things, the geographer requires also condensed statements of mat¬ 
ters of fact and inference, to aid in the construction of his com¬ 
pendious books, whether he has to prepare these abstracts or finds 
them made ready to his hand. 
Thus also in Geology we have many useful catalogues of names of 
authors and books, and of fossils, rocks, and minerals. Some are in 
the form of dictionaries, some are regular bibliographical portions 
of periodical journals, some constitute appendices in books and 
memoirs, and some are published in an independent form. Some 
have succinct notices, descriptive or suggestive, attached to the 
subjects mentioned, and some carry much information in collateral 
columns, but many indicate nothing more than what the mere 
names and titles can suggest. Of those moro completely useful 
works which assist the geologist in finding what has already been 
done and thought of in this or that department of his science, the 
‘ Geological Record,’ edited by Mr. Whitaker, F.G.S., with the 
assistance of many other good and energetic geologists and mine¬ 
ralogists, stands high in worth and favour. It has no rival except 
the excellent ‘ Rovuo de Geologie,’ by MM. Delesse and Lapparent, 
which has reached its fourteenth annual volume, and worthily 
fulfils its useful mission among our fellow-labourers in France. 
In our ‘Record’ the distribution of matter is made thus: —
