He describes as new Gerres simillimus, the Pacific Coast re{)resenta- 

 tive of Gerres (or Xijstacma) cinercum. He regards Gerres axillaris 

 as distinct from Gerres I'mealus. Gerres cmbri/x and Gerres brasiUunus 

 are regarded as old examples of Gerres plumwri, a conclusion also 

 reached by the present writer. He regards Centropomiis pedimacula 

 of Poey as identical with Centropomiis pectinatus. The fish from the 

 Pacific called pedimacula he identifies as C. medius. C. mexicanus, 

 C. gahhi, and C. herimji are identified with C. para//rli,s. ( '. arr/mtcus
