2163. DIODON HOLACANTHUS, Linna3us. 



D. 12; A. 12. Very similar to Diodon hystrix, but with the frontal spines 

 usually longer than the spines behind the pectorals, about twice as long 

 as eye. Predorsal spines not shortened, 2-rooted, erectile; about 14 to 

 17 spines in a series between snout and dorsal; post-pectoral spines not 

 especially elongate, but movable ; pectoral broader than long, upper lobe 

 pointed, lower lobe rounded. Coloration much as in Diodon hystrix, but 

 more variable, the spots fewer and larger ; usually a broad black bar from 

 eye to eye, continued below eye as a narrow bar ; a broad bar across occi- 

 put; a black blotch above each pectoral; a short bar in front of dorsal; 

 another in which the dorsal is inserted ; a blotch behind the pectoral, and 

 many small spots and blotches on the upper parts; fins with few spots, 

 mostly immaculate in the young. In all warm seas, north to the Florida 

 Keys, Lower California, and the Hawaiian Islands, its range coinciding 

 with that of Diodon liystrix 9 from which it may prove to be not distinct. 

 An example before us is from La Paz. The distinctions are generally evi- 

 dent in the adult, bat young specimens apparently intermediate are often 

 found. Possibly the two are different sexes of the same species. Length 

 1 to 2 feet. None seen by us of as large size as the largest liystrix. (6ho$, 

 wholly; axay&a, spine.)
