ALEXANDER STRAUCH. 



THE death is announced of the eminent herpetologist, who has 

 for many years been Director of the Museum of the Imperial 

 Academy of Sciences at St. Petersburg. Though only in his sixty- 

 second year, Dr. Strauch had been in feeble health for some time 

 before his death, and had been unable to make much progress in his 

 favourite studies. His more important memoirs were published 

 by the Academy, and comprise, among others, an essay on the 

 Herpetology of Algeria (1862), studies of Chelonia (1862, 1865, and 

 1890), a synopsis of the Crocodilia (1866), a synopsis of the Viperidae 

 (1869), a revision of the Salamanders (1870), on the Snakes of Russia 

 (1873), and on the Geckos (1887). Dr. Strauch's memoir on the 

 Russian snakes is especially valuable, and it is a misfortune that he 

 was unable to complete similar memoirs on' the other reptiles and 

 batrachians of the empire. His contemplated description of the 

 reptiles collected by Przewalski remains unfinished.
