2.576. MICROGOBIUS THALASSIXUS, Jordan & Gilbert. 



Head 3^ in length; depth 4f. D. VII-16; A. 15; eye 3 in head. Body 

 elongate, much compressed, highest in front of ventrals, thence tapering 

 regularly to a Aerj- narrow, short caudal peduncle; the body with a pecu- 

 liar, translucent, fragile appearance, common also to Z. emhlemaiicus. 

 Head compressed, much higher than wide ; snout very short, acute, the 

 preorbital not as wide as pupil; mouth terminal, very wide and oblique, 

 the jaws equal; maxillary reaching vertical from middle of orbit, ^ length 

 of head; teeth in a narrow band in each jaw, the outer series enlarged, 

 canine-like (under a microscope the band of small teeth behind the outer 

 series seems evident, but the size of our specimens does not enable us to 

 verifj' it with certainty) ; eyes placed high, separated by a narrow ridge, 

 the diameter about *■ length of head. Dorsals very closely contiguous; 

 spines very slender, the fifth slightly produced and filamentous, reaching 

 (in our specimens) to base of third soft ray when depressed ; caudal lanceo- 

 late, very long and pointed, the middle rays produced, 2* in body ; jiec- 

 torals as long as head; the upper rays not silk-like; ventrals with basal 

 membranes well developed; the fin long, reaching to or slightly beyond 

 front of anal, somewhat longer than head. Body covered with rather 

 small cycloid scales; head naked; the scales very readily deciduous; 

 as they have in our specimens mostly fallen off, the count can not be given. 

 Head and body translucent, overlaid by brilliant green luster, which is 

 formed by exceedingly minute close-set green jioints; the luster is intense 

 toward the head, where it assumes a blue tint, and becomes hardly notice- 

 able on caudal peduncle ; 3 conspicuous translucent bars, wider than the 

 interspaces, crossing body immediately behind head; head with 2 bril- 

 liant narrow blue or green lines running obliquely across cheek below 

 eye; opercle with greenish luster; branchiostegal membrane white; dor- 

 sals whitish, with 2 or 3 lengthwise series of large reddish-brown spots; 

 spinous dorsal blackish at base ; upper caudal rays mai'ked with red, the 

 lower portion of caudal and the most of the anal fin blackish, anal Avhitish 

 at base, the anterior rays tijiped with brilliant white; ventrals light built'; 

 pectorals translucent. In spirits, the body appears dusted with dark 

 points; 2 light cross bars toward head; lower part of caudal and anal 

 black. Coast of South Carolina; two specimens, the largest Ik inches 

 long (No. 29674, U. S. Nat. Mus.), were taken in muddy tide pools in 

 Charleston Harbor. {f)a?iaddiv6<;, thalassinus, sea-green; OdXaddcx, the 

 sea.)
