which was unspotted. Kendall and Radcliffe, in Shore Fishes, 

 Albatross Eastern Tropical Pacific Expedition (p. 164), list three 

 very small individuals as C. angulosus, from station 4619, off the 

 coast of Panama, and state that Batistes adsyersus of Tschudi is 

 probably the same species. These small individuals had the sides of 

 the body dotted with small, round, white spots. The type of Can- 

 thidermis angulosus (Quoy and Gaimard) came from the Hawaiian 

 Islands. 



If the form found on the Pacific coast of America is found to be 

 different from the Hawaiian species, as seems highly probable, the 

 former would become C. adspersus. 



For the present we have provisionally adopted this name. 



The largest ipdividual taken off the coast of Panama, 21 mm. in 

 length, has the following measurements : Head 2.57 in length ; depth 

 1.63; eye 3.5 in head; snout 2; pectoral 1.55; first dorsal spine 1.4; 

 height soft dorsal 2 ; D. III-21 ; A. 20 ; P. 13 ; scales about 45 ; soft 

 dorsal, anal and caudal rounded; body dark brown with numerous 

 small, round white spots; fins yellowish.
