 Beetles" — he will find licre and there cause for criticism. In the 

 list of the families the Bui)restidie are omitted altogether, the 

 Xitidulidic consist of a mixture of various Clavicornes, Blethisa is 

 wrongly placed under the tiger-beetles (Cicindelidtc) and Deronectes 

 under the whirligig- beetles (Uyrinidio), and so on. Nevertheless, a 

 beginner will find much to help him in naming his captures.

 Vice-President, in the Chair. 



Dr. A. S.Mii'ii Wdodavaiu) described certain photo2;i*aphs 

 (natural size) oi Dcsmosfi/hia teeth from the Lower Miocene 

 Sandstone of Southern Vancouver Island (B.C.) exhibited 

 by Ira. E. Cokxwall, F.CKS. 



The exiiibitor wrote tliat tlieso Desmnnfi/lus teetli are slightly 

 different from any found in either California or Jajian, as tlu'V 

 show a well-developed cinguhnn. They may be from an older 

 s])ecies than Desmosfj/his hesperus, as recent research has shown 

 tliat 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 191G 

 in the face of the sandstone-cliff west of Muir Creek, Sooke Jiay, 

 Southern Vancouver Island (B.C.). It was determined by the 

 late Lawrence M. Lambe as the first right upi)er molar of 

 iJesmosti/hts hesperus Marsh, and is now in the British Columbia 

 Provincial Museiun at Victoria. The dimensions of this tooth 

 are: Length = 34 mm.; width = 24 mm.; height of columns
