Measured obliquely from the muzzle to the posterior angle of the 

 opercle, the length of the head is £ of the total. The diameter of the 

 eye is T ^ of the length of the head ; the distance from the muzzle is 2 

 diameters ; that across the arched forehead 4. The angle of the mouth 

 is at the posterior fourth of the length of the head ; the jaws are 

 equal. All the teeth are excessively slender, recurvous, and, like those of 

 some of the Gobioidce, erectile, but not flexible. They may be raised 

 or laid down in the manner in which Cuvier describes the teeth of his 

 genus Salaiias, like the keys of a Piano. Those of the jaws and some 

 of the palatals have a single barb at the posterior margin of the point ; 

 a few of the former are arrow-shaped. In both jaws appear three 

 series of somewhat distant teeth : the external consists of excessively 

 minute ones, the second of longer, and the internal series of the 

 longest of all. Those of the lower jaw are longer than those of the 

 upper, particularly three or four on each side of the symphysis. The 

 pharyngeal .and palatals consist of two series. The fourth anterior 

 tooth of each palatal is very long. The tongue is very short, linear, 

 and covered with fine teeth, like those of the hyoid bone and the upper 

 margin of the branchial arches. The opercles are membranous, dia- 

 phanous and appear all blended together. The branchiostegous mem-
