Tlu Britisli Tertiiiry Erhinoitl Faunns und tluir ApinitirK. — J. W. 
Gregory, F. G. S. 45 pp. I fig. in text. (Proc. Geologists' Association, 
London, Pts. I and II, ISill.) This is a most important memoir, cover- 
ing, as it does, the entire Tertiary fauna of the British Isles: the work, 
however, is deficient in illustrations of the new species described. 
There is reference to two plates, and it is presumed that they will appear 
with the next number of the Proceedings. Six new species are de- 
scribed of which four are from the Eocene. According to this author, 
there are 7 genera and 14 species from the Eocene, 11 genera and 21 
species, of which 9 are Eclnnns, from the Pliocene, and five genera and 
seven species, of which 'i are Echinus, from the Pleistocene. The author 
concludes that the cause of the small number of British echinoids is 
due entirely to climatic and lithologic conditions; in the Cainozoic, tlie 
British seas were cold and free from reefs, both conditions unfavorable 
to the growth of echinoids. The author also favors the view that a belt 
of shallow water connected the south of Europe with America during 
the Cainozoic. A bibliography is appended in which are cited 4!> 
authorities. 
The Mexii-juf und Tertiary Inscfts of Xrw South Waks. — R. Etueuidok, 
Jim. and A. S. Oij.iff, 14 pp., 2 heliotype plates. (Memoirs Geol. Sur. 
New So. Wales, Xo. 7, 1890.) There are but few Tertiary insects (hai'dly 
a dozen) known from the Australian continent, therefore this contribu- 
tion is particularly timely and important. There are described two new 
genera ( Mrsoxtif/inodcru, belonging to the familj' Jhiprcstida' and Fidaidi/rns 
belonging to the family Liiiiipi/ridu', both Coleopteral and five new 
species. 
0)1 the Ontcolof/i/ of Po'brotJieriuiii, — W. B. Scott, Princeton f.Tour. 
Morph. Vol. V, Xo. 1, June, 1891), pp. 74, 3 pis, and figs, in text. This 
leiirned author's '"Contriljution to the Phylogeny of the Tylopoda" is a 
beautiful illustration of systematic work. He first gives some interest- 
ing examples in evolution and then takes up the Pti'hrotln rimu, which 
he is better able to describe tinin any other person, not only on account 
of his well known ability so to do, but also by the fact of the posses- 
sion of an almost complete skeleton; this skeleton having been discov- 
ered by that indefatigable collector, Prof. W. F, Magie, upon the grouml 
which a few months later (in 1890) Avas made memorable by the Indian 
outbi'eak. This skeleton, together with a nunil)er of other parts, has 
enabled Prof. Scott to render tiiis important contrilmtion, and the 
thorough study of l*n>hrothcriiini is indicated by the large numlx-r of 
pages devoted thereto. Tliere is, however, one fault to be found witli 
this paper, viz: the metliod of giving references, which are numbered.
