This species of goby is readily recognized in the field as well as in the laboratory 
by two characteristic dark spots on the base of the caudal fin, one above and one 
below, separated on the mid line by a yellowish area. These spots are frequently 
more or less confluent either with each other or with other blotches on the caudal 
peduncle, but the characteristic pattern is readily recognizable in every case and is 
present in both sexes at all stages of growth from 15 millimeters and larger (15 milli- 
meters being the smallest specimen examined). 
Body elongate; snout obtuse in front; mouth nearly horizontal, subinferior, 
the upper jaw being longer; gape entirely below level of eye; maxillary extending to 
vertical through middle or nearly to posterior margin of eye; lower jaw of female 
rather thin and frequently somewhat angular in front, this character sometimes being 
rather striking in specimens preserved with their mouths open, or in those having the 
soft part partly shrunken; the lower jaw heavier and more rounded in the grown 
male. Caudal fin rather long and pointed in male, shorter and nearly rounded in 
female; second to fourth rays of first dorsal quite long and filamentous in full-grown 
male, sometimes nearly reaching the caudal when laid back; only slightly filamentous 
in female, not reaching past fourth ray of second dorsal; ventral somewhat longer 
and dorsal and anal somewhat higher in male. Anal papilla in male an elongate 
pointed flap, in female a fleshy bulbous tubercle. The changes in the structure of 
the teeth with sex and age described above. 
The fundamental color pattern on the body may be stated to consist of a series 
of six blotches along the mid line of the sides and another series of blotches along the 
back placed over the interspaces of the median series. All of the blotches are more or 
less coalescent producing a rather irregular mottled appearance, but in some speci- 
men ts the two series of blotches may be vaguely discerned; a number of vertical 
narrow bars frequently more or less distinct on lower half behind vent, in medium 
sized or large specimen, and are especially well marked in large males. Three or 
four short oblique streaks below the eye. Two characteristic dark blotches on base 
of tail, separated by a median yellowish area, as described above. Dorsals, caudal, 
and pectoral in females and young males streaked with rows of small spots; in large 
males the spots on the dorsals being fewer, confined to the basal third, more prominent, 
somewhat larger, and frequently more or less ocellated with white, especially in largest 
males. Ocellated condition of spots especially marked on first dorsal. First dorsal 
with irregular black blotches in addition to spots, one blotch on middle extending on 
back. In full-grown males the caudal becomes uniformly dusky with two longitudinal 
rose red bands in life, one above and one below the mid line; the upper band usually
