Dr. Kavip wa.s specially occupied for some years with the birds of prey, publishing mean- 

 while numerous papers. Three of these are upon Strigidce — Isis, 1848; Contr. Orn., 1851-52, 

 and the present one. Ho coined many new generic names for these birds, several of which 

 have proven available ; but his work cannot be considered of great merit or utility, and would 

 be scarcely remembered were it not for tlje new genera proposed. His classification is hope- 

 lessly vitiated by his ' quinarian ' freaks, and his w.ay of working out species has the reverse 

 of felicitous result. I should not be disposed to take issue with any one who might go so far 

 as to consider the author in mention a magnificent failure.
