Papillae -

Color - Life colors unknown: Preserved color - A pallid goby with little in the way of obvious or distinct dark markings. The most apparent color marking is the narrow, verticalally elongate black bar at the base of the caudal. The most characteristic feature of its pigmentation, howver, is the presence of two narrow black parallel lines of melanophores extending backward from the center of the eye. These lines probably included a band of some other color in life. There is also a similar arrangemnet of narrow parallel dark lines extending from the mid-ventral edge of the eyeball to the posterior end of the maxillary. In large adults, still other of these markings appear, most notably one above and paralleling the above mentioned postocular marking and another, less distinct, coursing laterally on the upper portion of the cheek. All fins punctate, the pectoral and caudal least so. Melanophores not forming obvious patterns except on the anal fin; on the anal the pigment exists as a band through the center of the extended fin, both the bases and the tips of the rays and interradial membranes clear. A patch of melanophores present on the chest in front of the ventral fins and, ventrally, in a cheveron-shaped patch on the branchiostegal membranes. A patch, U-shaped in adults, of melanophores present on snout. Three dark transverse markings cross the protruding upper edges of the eyeballs. The bodies of all but the larger specimens mostly unmarked. The larger individuals have scattered pigmentation on the body but in gross examination are still pale; these also develop six indistinct dorsal blotches whain are evenly spaced between the origin of the spinous dorsal fin and the last segmented dorsal ray.
