the longest, li in head. Ventrals short, having- 1 spine and 4 rays, 

 their length '2^ in head. Anal spines graduated in length, the soft 

 anal rays much longer, 3 in head. Ca idal short and rounded, equal 

 to length of ventrals. 



Body scalcless; 3 or 4 rows of wart-like papillse scattered over the 

 back, and a few snialler ones above anal. 



Color in spirits: Back and sides light brownish; top of head at 

 interorbital space and a spot at pterotic region frosted with white; 

 from base of second to seventh dors^il spine a pinkish red band 

 extends downward to lateral line, a similar one on last 3 spines and 

 entire soft dorsal extends down nearly to anal; a pinkish ])and mixed 

 with tine brown lines across basal half of caudal, and one across tips 

 of rays leaving a white band between; middle of soft dorsal with a 

 white band across all ra} s but last 2; pectoral In-own, crossed by hne, 

 dark brown lines, a white spot on upper rays; ventrals and anal similar 

 to dark part of pectoral; traces of pink on interorbital and sul)or])itals. 



A smaller .specimen has the pink very l)right, and in addition has 

 pink on opercles, on occipital region, and on basal two-thirds of pec- 

 toral. Another specimen has much milk white about the head, and 

 the lower parts of body are lighter. 



A fourth specimen differs in being nearly uniforml}' dusky orl)hick- 

 ish on ])ack, and in having the lateral line rumiing in a white streak; 

 fins marked similarly, but with ])lackish instead of red or dark ])rown. 



Several specimens from Misaki, the largest 120 nnn. in length. 



18. INIMICUS Jordan and Starks. 

 Iiiniicus Jordan and Starks, new genus (jdiKyiiinia). 



Body elongate, little compressed, anteriorly low^, covered with 

 smooth skin; head depressed, fantastically formed; body, head, and 

 fins with skinny flaps; mouth small, subvertical; teeth on vomer, none 

 on palatines; dorsal spines slender, about 17 in number, the 3 anterior 

 separate from the rest, the others connected by mem])rane at base. 

 Pectoral tin large, the upper ra3^s not tilamentous, the 2 lower rays 

 detached, connected by membrane at base. Ventral rays 1, .5, the fin 

 large. Fantastic, misshapen fishes often highly colored; dreaded l)y 

 fishermen for their stinging spines. This genus differs from Pelor 

 {filaiiwntosmn) chiefl}^ in the absence of long filamentous tips to the 

 upper rays of the pe(;torals. The head is more depressed and some- 

 what differently formed.
