second is posterior to the edge of the preoperculum, but interrupted in 

 the middle so as not to cross the operculum ; the third is posterior to 

 the first ray of dorsal ; the fourth posterior to the spinous rays of anal ; 

 the fifth posterior to the end of the dorsal and anal ; the sixth passes 

 across the base of the tail. Between the third and fourth bands are 

 short bars, one proceeding from the dorsal, the other from the ventral 

 outline in the same vertical line, and parallel to the others. This may 

 in fact be described as an additional bar interrupted in the middle. 



Fins greenish yellow, with mottlings of dark. Ventrals black cen- 

 trally, yellow posteriorly, and deep I'ed on the two anterior rays and 

 intermediate membrane. Dorsal with the three anterior rays and their 

 membrane black; the membrane between the third and fourth rays 

 red. Pectoral plain- 

 In large specimens the tints are darker, and the ground color tinged 

 with olivaceous. The red of the dorsal is not distinct. Length three 

 inches.

 sion above the eye. Snout very much abbreviated ; lower jaw 

 longest. Mouth large; posterior extremity of maxillary extending to 

 the vertical posterior rim of eye. Diameter of the eye contained

 two sevenths of total length. Six rows of scales above the lateral 

 line; twelve row\s beneath. Lateral line concurrent with the dorsal 

 outline. Spinous portion of dorsal quite low, and extending over a 

 base twice as long as the soft portion. Caudal rounded posteriorly. 

 Anal extending a little more backwards than dorsal. Five short 

 anal spines. External soli, ray of ventrals extending as a filiform 

 appendage beyond the other rays, which do not reach the anterior 

 margin of the anal. Tip of pectorals extending to a vertical \vhich 

 would intersect the vent.
