the “ Vertebrates” are dealt with under Chapters I.-VI., and the 
* Invertebrates” under Chapters VII.-XV.; Part II., the “ Vege- 
table World,” illustrated by many text-figures, extends to five 
chapters. In the “Introduction ” there are suggestions as to the 
necessary apparatus for the naturalist ; the ‘* Appendix” is headed 
“Some wild pets | have known ”—five in all. ‘The Insects occupy 
pp. 181-299, illustrated by 11 plates, 3 of which are printed in 
colours. ‘The representative figures of the beetles, 233 in number, 
occupying 4 plates, photographed natural size, are poor; those of 
the butterflies and moths fairly good. But if a specialist starts to 
analyse the text—say, the article headed “Some common British 
Beetles”—he will find here and there cause for criticism. In the 
list of the families the Buprestide are omitted altogether, the 
Nitidulids consist of a mixture of various Clavicornes, Blethisa is 
wrongly placed under the tiger-beetles (Cicindelide) and Deronectes 
under the whirligig-beetles (Gyrinidie), and so on. Nevertheless, a 
beginner will find much to help him in naming his captures. 
Works on special subjects would, of course, be required by the 
collector when more accurate detail is required. The book is well 
printed and indexed, and the price at the present time is not high.

March 8th, 1922.—Mr. R. D. Oldham, F.R.S., 
Vice-President, in the Chair. 
Dr. A. Smira Woopwarp described certain photographs 
(natural size) of Desmostylus teeth from the Lower Miocene 
Sandstone of Southern Vancouver Island (B.C.) exhibited 
by Ira E. Cornwatt, F.G.S. 
The exhibitor wrote that these Desmostylus teeth are slightly 
different from any found in either California or Japan, as they 
show a well-developed cingulum. They may be from an older 
species than Desmostylus hesperus, as recent research has shown 
that the formation in which they were found is at least Lower 
Miocene, while the formation in which Desmostylus remains have 
been found in California is Middle Miocene. 
One of the teeth shown in the photographs was found in 1916 
in the face of the sandstone-cliff west of Muir Creek, Sooke Bay, 
Southern Vancouver Island (B.C.). It was determined by the 
late Lawrence M. Lambe as the first right upper molar of 
Desmostylus hesperus Marsh, and is now in the British Columbia 
Provincial Museum at Victoria. The dimensions of this tooth 
are: Length =34 mm.; width =24 mm.; height of columns
