Body-rings eighteen, caudal rings twenty-eight, dorsal rays forty- 

 five, commencing before the vent and extending on one-and-a-half plus 

 seven rings. Snout slender and compressed; its length is contained 

 •one and five-eighths times in total length of head. Diameter of eye 

 •contained five and one-half times in length of snout and eight and one- 

 iifth times in total length of head. Space from the anterior border of 

 the orbit of eye to the posterior border of the opercle is contained one 

 ■and five-eighth times in the length of snout. Head is contained in 

 total length, including caudal, five and three-fourths times. Depth 

 of body before dorsal is contained two times in the space between the 

 posterior border of the opercle and the anterior border of the orbit of 

 the eye. Distance from vent to tip of caudal is contained in the dis- 

 tance from vent to tip of snout one and seven-hundredths times. Keels 

 sharp and high; each body-ring bearing two ventral, two lateral, and 

 two dorsal keels. Lateral line interrupted above the vent. Five 

 radiating ridges pass from the anterior border of the opercle backward 

 and downward. The uppermost dorsal ridge passes ventral to the 

 blotches. The three central ridges are visible without lens. The upper 

 two-thirds of the opercle covered with brown blotches. A brown line 

 commences on the anterior ventral border of the snout and passes 

 backward and laterally through the eye and along the dorsal border
