Mendips. The associated volcanic rocks, the Old Red Sandstone and 
its fish-remains, and the zones in the Carboniferous Limestone Series 
are more particularly described, brief references only being made to 
the Coal-measures. 
“The Neozoic Rocks of Gloucestershire and Somerset,’’ including 
accounts of various formations from the Bunter to the Chalk and 
superficial deposits, are described by Mr. L. Richardson. As might 
be expected more details are given of the Rhetic Beds, with their 
basal grey marls, termed Sully Beds, that have yielded <Avicula 
| Pteria| contorta and Ostrea Bristow: ; of the Lias and Inferior Oolite 
and their ‘hemere’. ‘he geological history after the Cretaceous 
Period is briefly sketched, and full references are given to the 
literature of the Drift deposits. 
‘« Dorset—Inland ” is the title of an article contributed by the late 
W. H. Hudleston, and it is prefaced by a list of names of fossils and 
zones adopted by him, with remarks upon them, drawn up at his 
request, by Mr. 8. 8. Buckman. We must confess to a preference for 
the names used by Mr. Hudleston, whose judgment on these matters 
was always philosophic, sound, and practical. ‘lhe principal sections 
in the Inferior Oolite near Sherborne and Yeovil are described ; and 
an account is given of the Wareham District, with particulars of the 
well-boring at Bovington, and of the outlier of possibly Bembridge 
Limestone, discovered by the author at Creechbarrow Hill. 
“The Dorset Coast’’ is described by Mr. Monckton, who deals 
with the strata visited during excursions made to Lyme Regis, 
Bridport, Weymouth, Abbotsbury, and the Isle of Purbeck. 
‘“«The Isle of Wight ” is dealt with by Mr. Herries, who has given 
a concise account of the physical features and geology of this oft- 
visited geological paradise. 
There is therefore plenty of interesting and instructive material to 
be found in this part of ‘‘Geology in the Field ”, and it will be of 
essential service to all who visit the districts described.

FF\HIS volume, like the others of the series to which it belongs, is 
devoted to morphology and classification; it contains valuable 
and well-written accounts of the general characters of the Craniate 
Vertebrates, of the Cyclostomata and Gnathostomata, of the Fishes, 
and of the two main branches of the last-named, the Chondrichthyes 
and Osteichthyes; the results of Mr. Goodrich’s recent important 
researches on the exoskeletal structures of fishes and on the origin of 
limbs are here included. 
The morphological parts of the book suffer a little from com- 
pression, and from the paucity of references to function. The state- 
ment that the jaws developed from the first pair of visceral arches 
might have been qualified, for the labial cartilages may reasonably be 
interpreted as the remnants of pre- -mandibular arches.
