Head with cirri (in lateralis), or

A better distinction between Artedius and Axyrias is found in the pres-

Page 1898. The type number of Icelinus strdbo is 5045, not 5451. 



Page 1902. Artedius aspernlus is better separated from A. lateralis by 

 the coalescence of the bands of scales behind the dorsal and their con- 

 tinuance upon the caudal peduncle. In the description of the genus 

 Artedius the bands of scales are said not to meet behind the dorsal. This 

 applies to A. lateralis only. 



Page 1902. To the description of Artedius add: No patches of ctenoid 

 scales on the head. 



Page 1903. To the description of Artedius aspenilus add: Head with- 

 out cirri.
