Habitat: Pacific coast of tropical America, from Panama to Gulf of 

 California. 



Etymology; Analogufi^ analogous (to Kyphosus sectatrix). 



This species is generally common along the Pacific coast of tropical 

 America, wliere it represents the closely allied K. sectatrix. The spec- 

 imens examined by us are from Guaymas, Cape San Lucas, Porto Es- 

 coudido, aud Mazatlan.
