lu.lv moderately elongate, compressed, narrowing regularly from the 

 Bhoulder-girdle to the caudal tin : bead not greatly depressed, broader 

 than body, its Length being contained four times in total length of body; 

 snout rounded, short, aboutequalto diameter of eyes; interorbital space 

 narrow, not greater than half diameter of eye; mouth rather large, its 

 gape extending nearly to the vertical of posterior margin of orbit; 

 maxillary somewhat variable in length, but usually prolonged behind 

 eye for a distance nearly equal to diameter of eye; skull rather long, 

 medium cresl of cranium moderate, cross ridge across posterior part of 

 interorbital space well developed; scale small, cycloid, about fifty in 

 longitudinal series, eighteen in transverse; teeth in a single series on 

 premaxillaries and mandible short, blunt, and curved slightly back- 

 ward, most closely set and most numerous on premaxillaries. 



bins moderate: dorsal of five spines and sixteen soft rays, the spines 

 being unconnected with the rayed portion, the space between them 

 about equal to half diameter of eye; the spines are weak and flexible, 

 their length being one half that of the head; soft dorsal begins at a 

 point a little nearer end of snout than tip of caudal, and extends nearly 

 to the caudal, its height is about equal to that of the spinous portion 

 the first few rays being slightly graduated; the anal has fifteen rays 

 and begins a little behind the origin of the soft dorsal, the rays are 

 about equal to those of the dorsal in length; pectorals moderate, in- 

 serted a little below the axis of the body, their length greater than the 

 depth of the body, their tips reaching a vertical from posterior part of 

 spinous dorsal ; ventrals united but not aduate to the belly, inserted 

 slightly in front of the pectorals, and their tips do not quite reach those 

 of the pectorals. 



Ground color light, head and body pretty uniformly covered with 

 dark punctulations ; an irregular dark bar across occiput; breast and 

 belly pale; a row of nine or ten small dark blotches along the middle 

 of the side, the one at the base of the caudal being plainest and having 

 a shape something like the Greek letter T\ about six dark blotches 

 along median line of back. Peritoneum dark. 



The average length of over seventy specimens is about 33- mni , the 

 longest ■10""". 



This species is allied to G. guaymasice J. & E., from which it differs, 

 among other points, in its smaller size, shorter head, and its fewer fin- 

 rays. 



Numerous specimens of this little fish were found rolled up in the sea- 

 weed dragged out by the seine from the bay near the railroad station 

 at ( ruaymas.

Head :5 in length to base of caudal (3| in total); depth G (7); D. V- 

 11: A. l". : eye, 5. 



Body quite slender, elongate, but little compressed; head long, nar-
