This genus has been founded by Dr. v. Blocker on a Scaroid fisli 

 ivoxw Bahia, named Sau-us Jiavescens, in the Vienna Museum. I 

 thought for some time I had rgcognized it in some fishes with the 

 mandibulaiy teeth in distinct obli(]uc scries ; but these have a narrow 

 upper lij) double in its whole circuit, and are merely the young of 

 tScarus radians. 



The name of Sr. Jiavescens, proposed by Schneider for a fish figured 

 by J'arra, lam. 28. fig. 4, cannot he retained for a species of the genus 

 Calllfo(hntlchlh)/s. Parra's representations of the Scaroid fishes are 

 very faithful (mucli more so than the descriptions given by M. Valen- 

 ciennes), and Parra evidently rei)resonts a species with slender and 

 flexible dorsal spines, whilst Callijodontkhthys has these spines 

 pungent.
