238 Stejiieger — Some Generic S'amfx of Turtles. 



"Mr. (Ti-ay regards the Testudo Spongleri, Walb., as the 

 type of a new genus of Emydidm 



"From the beautiful h'gure of the animal of Em. spi)ios<t 

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

 (iray is inclined to believe that this species belongs to the same 

 genus with Em. SjHwghri..'''' 



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 (ireoemi/s in 183T with 

 (t. spengleri as tlie only species. 



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

 .^piiiot^a 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 

 IL-ostmys* with the three species JZeosemys spirtosrfy (jrandis 

 and depressa. 



The synonymy of the two genera woidd then stand as 

 Follows: 



Heosemys Slejneger.
