more than half length of second which is long. Preopercle with several 

 distinct flutings. Gill-flap rather narrow. Opercle smooth. 



Gill-opening extending forward not quite opposite to posterior 

 margin of pupil. Upper cleft of gill-opening extending forward a 

 little more than at a point equal to last f in length of head. About 

 15 + 28? small short rudimentary filamentous-like rakers on first arch. 

 Gill-filaments long, longest about 2 in horizontal orbital diameter. 

 Isthmus nearly forming an equilateral triangle. 



Scales moderately small, adherent, and forming longitudinal series 

 parallel with lateral line. Scales below lateral line, or those on breast 

 and abdominal region, a little larger than others. Scales passing over 

 ventral carina. No narrow median naked strip from occiput to dorsal, 

 scales passing over. Head naked. Scales on chest a little smaller 

 than those on breast. No scales on dorsals, pectorals and ventrals. 

 Base of caudal with scales, and along basal region of anal. Base of 

 ventral inside with a broad flat scaly flap, and another flap, but narrow 

 and at present equal to about f of fin (damaged), placed in axil. No 

 flap in pectoral axilla. Lateral line of simple tubes, continuous, 

 slightly decurved at first and then straight to caudal. 



Dorsal inserted about midway in vertical between tip of snout and 

 posterior basal margin of adipose fin. Dorsal high, first branched rays 

 evidently highest and others graduated down. Adipose fin well de- 

 veloped and its base about last f in space between dorsal and base of 

 caudal. Anal evidently low and its origin a little nearer base of caudal, 

 in vertical, than origin of ventral. Caudal emarginate (damaged), and 

 rays well branched. Pectoral small and low. Ventral inserted about 

 opposite base of second branched dorsal ray, and reaching about f of 

 distance to anal (damaged). Vent close in front of anal. 



Color in alcohol brassy-brown, back with a dull olivaceous tinge. 

 Fins all brownish. Iris deep brown. 



Length 4f inches.

One example, the type. This was long ago considered a new species 

 by Cope. It appears to be closely related to Curimata schomburgkii 

 (Giinther), but differs at once in the deep body, the upper profile of 

 which is more gibbous anteriorly.

Body well compressed. Edge of back rounded. Caudal peduncle 

 compressed. Head compressed, a little constricted inferiorly, upper 

 surface convex. Nuchal region also convex. Head of rather even
