Figures occur all through the paper, showing details of 

 the several species described in the text, and an appendix is 

 added, containing twenty single plates and one double plate, 

 admirably figured and finely printed, in which the leading

 publication does credit to the department issuing it, and can- 

 not but add to the reputation for careful investigation and 

 solid thinking of Mr. Lambe, whose good work it makes 

 known. — R. C.
