Body elongate, well compressed. Head small, compressed, greatly 
shorter than trunk. Snout very short, obtuse. Eye large, greatly 
exceeds snout or muzzle, well advanced in head, impinging on upper pro¬ 
file of head. Mouth moderate, terminally superior or with mandible 
little protruded in front. Teeth uniserial, large, simple, well spaced. 
Maxillary oblique, extends below eye. Interorbital rather broad. Head 
unarmed, without spines. Gill opening lateral, oblique, rather close 
before pectoral. Scales present on trunk and tail, very small on pre¬ 
dorsal, chest and breast, large on prepectoral and on tail posteriorly. 
Two dorsals, first of 6 slender spines of which first prolonged as fila¬ 
ment which would reach base of last dorsal ray, and soft fin with spine 
and 28 rays. Anal little shorter than soft dorsal, with spine and 24 
rays. Caudal rather large, ends posteriorly in median point (now 
Pectoral short, low. Ventrals well separated, inserted little 
before pectoral base, slender, moderate. 
I frame this genus for an exquisite little eleotrid, with its 
second and third dorsal spines ending in a prolonged filament; peculiar 
facies of head with very short snout, large eye and strong jaws, and long 
soft dorsal and anal; also a color pattern of greatly pleasing and con¬ 
trasted design.
