HeatI 3j in Icnj^th; depth at liasc of ventrals 4, at middk- of abdomen t,'j; least depth of 

 cniuhil |icdiinelc 3 in length of head; snout 4; eye 4 to 4J; lonj^jest dorsal spine 2jj; last dorsal spine 

 7,1: lonjjest (tenth) dor&il ray 2; longest (fifteenth) anal ray 2I; ventrals ij; lonj^est pcdoral ray ig 

 to ij; auidal il. I)ors:il XII, 15 or 16; anal II, 17; pectorals 14; ventrals I, 4. 



Robust, nioilerately compressed, with wide heavy head and short bluntly rounded snout, the 

 anterior prolile of which is nearly vertical. In sha])e and yeneral api>earance much resembling Hypso- 

 hlftiniiis gilhcrti. Mouth very wide, horizontal, short, the maxillaries reaching vertical from hinder 

 eilge of pupil, 3 to 3J in head. Teeth as usual in this grou]), the posterior not enlarged or canine- 

 like. Nostrils with slightly elevated margins, scarcely tubular, the hinder edge of anterior nostril 

 prcKluced into a conspicuous laciniate llai), about two-thirds as long as the diameter of orbit. A similar 

 but larger orbital cirrus, divided nearly to the base into si.x or eight slender filaments. Interorbital 

 space deeply grooved, without median ridge, opening posteriorly into the deep transverse groove 

 which sejxirates the orbital region from the somewhat swollen occi])ut, its width i .\ eye. The mucous 

 canals of head give off transverse branches which o])en by numerous pores, which thickly beset the 

 snout, subocular region, top of head, preopercle, and upper portion of opercle. Width of gill-slit 

 ecpialing or slightly exceeding one-half length of head, confined to area above lower base of pectorals. 



First dorsal spine over margin of jireopercle; spinous dorsal low, of nearly uniform height, 

 much lower than .second dorsal, the spines rather strong at base, with weak reflexed tips; membrane of 

 last dorsiil ray joined to extreme base of rudimentary caudal rays. Anal low, rising slightly poste- 

 riorly, leaving a short free interval between its last ray and the caudal. 



Lateral line strongly developed anteriorly for a distance equaling length of head; from that 

 [X)int it is only faintly visible, declining abru])tly to middle of sides, along which it may be traced to 

 base of caudal; the anterior portion gives off numerous pairs of short transverse lines, each of which 

 ends in a pore; no pores or lines are visible jjosteriorly. 



Blackish, without sharp markings, the sides with irregular light blotches, some of which are 

 subcircular in outline and contain one or more black central specks; the light markings near the back 

 are elongate and vertically placed, faintly outlining dark bars of the ground color; lower [larts lighter. 

 A vertical black blotch on cheek behind eye; no distinct bars on head; tentacles whitish. Fins all 

 blackish; the anal, the ventrals, the lower caudal and pectoral rays deeper black; anal and caudal 

 margined with white, some of the dorsal rays narrowly tipped with white. 



Two speciraetis, 102 and 115 mm. long, from Panama Bay. 



341. §cartichthys rubropunctatus {Cuvier <i- Valenciennes). 

 Recorded once from Panama (Jordan & Gilbert, 1882 n, p. 628). 



342. Rupiscartes atlanticus {Cuvier & Valenciennes). 



There is no Panama record for this species, which is known, however, from 

 the Mexican coast to Guayaquil (Boulenger, 1898-9, Vol. XIV, p. 8). 



343. Emblemaria nivipes Jordan <£.■ Gilbert. 

 The type from Pearl Islands, Panama Bay; not seen by us.
