base of the fin more than .5 trunk, the last rays reaching beyond base of outer caudal rays; 

 anal fin directly under soft dorsal and of same length, but the rays 18 in number and somewhat 

 shorter; caudal large, broad, and pointed, its length greater than head; pectorals very broad, 

 their insertion slightly in advance of dorsal, their broad base equal to .5 length of head, their 

 length about equal to head and extending beyond origin of anal ; ventrals large, nearly as long 

 as head, reaching to anus, the basal membrane very well developed and nearly .33 length of 

 fin. Color: body and head uniformly pale clear green, each scale with a fine dark edge; 

 anterior half of body marked by 5 or 6 pale, narrow, vertical crossbars, widest anteriorly, 

 placed at irregular intervals; a similar bar at base of caudal; spinous dorsal with 4 oblique 

 rows of dark spots on membranes; soft dorsal with 5 or 6 similar rows of spots; anal dusky, 

 the distal margin of each membrane except the first, sixteenth, and seventeenth having a 

 vertically elongated distinct black spot in a clear area, 'these spots forming a regular row; 

 caudal, pectorals, and ventrals dusky. 



Fig. 168. Holmes' Goby. Microgobius holmesi. a. Ventrals fins viewed from below. 



Type, a specimen 1.75 inches long taken on Uncle Israel Shoal, Beaufort 

 Harbor, July 20, 1904, by Dr. E. W. Gudger. 



Named for Prof. J. A. Holmes, former state geologist of North Carolina, now 

 associated with the U. S. Geological Survey. 



This species resembles Microgobius thalassinus Jordan & Gilbert, from 

 Charleston, S. C, but differs in having a much deeper caudal peduncle, a pro- 

 jecting lower jaw, shorter maxillary, smaller eye, no filamentous dorsal spines, 

 shorter caudal fin, more numerous anal rays, shorter ventrals, persistent scales, 

 and in color of dorsal, caudal, and anal fins, body, and head. 



• From Microgobius eulepis Eigenmann & Eigenmann, from Fortress Monroe, 

 Va., this species may be distinguished by its rather larger head, deeper and much 

 more compressed body, longer snout, longer caudal fin, absence of a sharply 

 defined black spot on spinous dorsal fin, and various other characters of form 

 and color. 



Only a single specimen is as yet known, but other examples will no doubt 

 be collected at Beaufort and other points.
