says that it is similar in its structure to that in the Gobies, and that 

 neither radius nor ulna is notched. The carpal bones are in two 

 series, united, however, in very large specimens. The pubic bones 

 are flat and separated. 



There are twelve abdominal and fourteen caudal vertehrce, the 

 former portion of the vertebral column being somewhat shorter 

 than the caudal. Eibs and processes rather feeble, much inclining 

 backwards.

Vomerine teeth in a crescent-shaped band. Twenty-six series of 

 scales between the occiput and the anterior dorsal fin, eighteen be- 

 tween the origin of the posterior dorsal and the anal, twenty-two 

 below the first dorsal spine. The height of the body is contained 

 five or six times in the total length, the length of the head three 

 times and a half. Snout produced, depressed, with the lower jaw 

 prominent ; the maxillary extends nearly to below the middle of the 

 eye ; teeth cardiform posteriorly. The vertical diameter of the eye 

 is one-half the width of the interorbital space Yellowish, irregu- 

 larly spotted with brown ; back with five dark cross-bai-s, appearing 

 in specimens preserved in spirits. A red spot and, above it, a black 

 one on the upper portion of the root of the pectoral ; three red 

 streaks radiating from the eye ; the vertical fins dotted Avith red and 

 yellow (the red colom's change into blackish after death).

This species is certainly different from E. dormiUitrix, having a 

 stouter habit, larger scales on the nape, &c. ; but the genus Lembus 

 is perfectly identical with Ph'dypnus of Valenciennes. The number 

 seven for the dorsal spines was given erroneously in my former de- 

 scription, drawn up from a specimen in an incomplete state of pre- 

 servation. The specific name must be altered, if Lembus maculatus 

 and Scicena maculata, Bl., are referred to the same genus.
