 (Recent authors in America have generally considered the green form 



mexicanus and the brown ionn fusco-striatus.) 



The synonymy of triops, obtusus and dissirniUs has long been 

 established. The descriptions originally given under each of these 

 names are wholly uncertain, but Stal, in 1874, having examined 

 the type of triops and studied Harris' adequate description of 1862 

 of dissimilis of Serville, stated these two to be the same. Serville's 

 species in unquestionably that which we have been calling 77iexi- 

 canus (green color phase), a,nd fusco-striatus (brown color phase), 

 as all other recent American authors have done, but, unlike the 

 majority of these, we have not applied the name triops to the 

 form properly designated as retusus. It is not surprising that 

 Saussure, in 1859, described mexicanus, thereby erecting another
