The length of the head is contained once and one-third in the 

 distance of the gill-opening from the origin of the dorsal fin, one- 

 half of its distance from the vent, and conspicuously more than 

 the distance between the commencement of the dorsal and anal 

 fins. Snout long, depressed, spatulate ; lips fleshy. The cleft 

 of the mouth extends to the vertical from, or scarcely beyond, 

 the hind margin of the eye, which is small. Vomerine teeth in 

 a band, which is rather broad anteriorly, being broader in the 

 middle than the maxillary band, and extending equally far back- 

 wards. The mandibulary band of teeth is longitudinally divided 

 by a narrow groove. Tail not much longer than the body. 

 Upper parts greenish, with numerous black spots which disappear 

 with age.
