This species is the Pacific representative of Hcemulon acutum. It 

 reaches a similar size, is equally abundant, and passes through a similar 

 range of variations and coloration. 



Most of the specimens collected by Professor Gilbert at Mazatlan and 

 Panama have 11 dorsal spines and correspond to the Hcemulon undeci- 

 male of Steindachner. Two or three of them have, however, 12 dorsal 

 spines, as in the original types of H. scudderi and H. brevirostrum. We 

 are unable to detect any other difference of importance among these 

 specimens, and refer all to H. scudderi, regarding it as a species with 

 the number of spines indifferently 11 or 12. No other species of Hcem- 

 ulon ever has fewer spines than 12. If these should finally prove to 

 be specifically distinct, the form with 11 spines should stand as Hcem 

 ulon undecimcde, that with 12 spines as Hcemulon scudderi. The above 

 description is especially taken from a specimen of the undecimale type.
