Color in alcohol, pale brown, side with 5 large brown blotches, and about 1 1 brown vertical cross- 
bars running closer together above to form pairs, though becoming indistinct on middle of side; a 
narrow blackish line across top of head down behind and below eye to corner of maxillary; a blackish, 
brown blotch at base of pectoral; spinous dorsal dark gray with oblique dusky hues; soft dorsal pale 
with a number of longitudinal dusky lines sloping backward; anal dark gray, the membrane between 
the rays blackish; caudal grayish with cross series of dusky spots; pectoral pale gray; ventrals gray 
black, margin and anterior portion pale brown. Described from an example (No. 846) taken at Hilo. 
The species is common along the shores and in shallow water about Honolulu, Waikiki, and Hilo. 
The collection contains 48 examples 2.4 to 8.8 inches long.

Genus 237 VITRARIA Jordan & Evermann. 
Body elongate, translucent, covered with very small, thin scales; mouth small, oblique; teeth 
minute; gill-opening rather narrow; dorsals small, the rays vii-11; pectoral rather long; ventrals small, 
united in a circular disk. Small gobies of the coral reefs, allied to the Japanese genus Clariger, hut 
with the first dorsal of 7 small spines instead of 3.

Head 4.6 in length; depth 6.7; eye 3.5 in head; snout 4.5; D. vii-11; A. i, 10. 
Body elongate, slender, compressed, greatest depth between dorsal fins; head elongate; pointed, 
conic, depth 1.75 in its length, width 2; snout rather long, rounded; jaws prominent, upper slightly 
produced; mouth oblique, maxillary reaching a little beyond anterior margin of eye; teeth not evident, 
tongue broad, truncate; snout above interorbital space and top of head more or less flattened; nostrils 
well separated, anterior nearly midway in length of snout, posterior close to front of eye; eye rather 
large, anterior; gill-opening restricted to side, rather small; scales very small; dorsal spines flexible; 
first dorsal small, the last 3 spines very small (minute stubs, broken in the type) , the fin beginning 
behind tip of ventrals; soft dorsal beginning a little nearer base of caudal than tip of snout, about 
over insertion of anal, anterior rays of both tins longest, those of anal gradually smaller behind, the 
last 2 minute and close together; caudal emarginate, lobes rounded; pectoral rather long, lower rays 
longest; ventrals small, united to form a small round disk whose diameter is 2.25 in head; caudal 
peduncle compressed, elongate, its length equal to head, its depth 2.25 in head. 
Color in alcohol, very pale translucent brown, 7 V-shaped pale brown markings on upper side of 
body united over back; fins whitish. 
We have examined 7 examples obtained at Hilo, each about 1.2 inches in length.

Genus 238. CHLAMYDES Jenkins. 
This genus is distinguished from Gobius and Mapo by the presence of scales on sides of head.
