238 Stejneger Some Generic Names <>f 



44 Mr. Gray regards the Testudo Spenglcri, Walb., as the 

 type of a new genus of EmydvdcB 



4 * From the beautiful figure of the animal of Em. spit'tomr 

 given by Mr. Bell in his 'Monograph of the Testudinata' Mr. 

 Gray is inclined to believe that this species belongs to the same 

 genus with Em. Spengleri." 



As will be seen nothing could be more explicit. The genus 

 was also so accepted by contemporary authors as shown by 

 Bonaparte's use of the emended name Geoemys in 1837 with 

 G. spengleri as the only species. 



That Gray himself afterwards (1855) shifted the name to G. 

 spinosa has nothing to do with the case, except that it necessi 

 tates the coining of a new name for the genus for which the 

 latter species stands as type. As a substitute I would propose 

 Jleosemys* with the three species JJeosemys spinosa, grandi* 

 and depressa. 



The synonymy of the two genera would then stand as 

 follows: 



Heosemys Stejneger.
