•posterior extremity of maxillary extending to a vertical line drawn back of 
the pupil. First dorsal lower than the second. Caudal lanceolated. Anal 
fin as long as the second dorsal. Ventrals not reaching the vent. Pectorals 
extending as far back as the ventrals. 
Log. — St. Joseph's Island, Texas ; G. Wurdemann. 
9. GoBius LYRicus. — Head rounded anteriorly, contained five times and a 
half in the total length ; jaws subequal ; gape of mouth nearly horizontal ; 
posterior extremity of maxillary reaching a vertical line drawn through the 
pupil. Dorsal fins not contiguous. Middle rays of first dorsal filiform, men- 
branous at their tips, higher than the second dorsal, the posterior rays of 
which, as also those of the anal, reach the base of the caudal. The latter is 
lanceolated, and the anal nearly as long as the second dorsal. 
Log. — Specimens were collected by Gr. Wurdemann, at Brazos Santiago, 
Texas. 
10. GoBius wuRDEMANNi. — General appearance like the preceding ; the head 
is larger, the caudal fin shorter, and the anal not quite so deep. The scales 
being smaller also. 
Log. — From Brazos, Santiago Texas, collected by Gr. Wurdemann. 
11. GoBius CATULus. — Head somewhat less than the fourth of the total 
length. Jaws even ; gape of the mouth slightly oblique ; posterior extremity 
of maxillary extending to a vertical line intersecting the pupil. Dorsal fins 
not contiguous ; base of the second somewhat longer than that of the first. 
Caudal posteriorly rounded. Anal rather short, and nearly as deep as the 
second dorsal is high ; its origin being situated opposite the third or fourth 
ray of the latter mentioned fin and nearly even with it behind. 
Log. — Specimens procured at St. Joseph's Island by G. Wurdemann. 
12. GoBius GULOsus. — Head elongated and compressed like the body, consti- 
tuting about the fourth of the total length. The snout is subconical ; the 
mouth large and very deeply cleft, with its gape oblique, and lower jaw slightly 
longer than the upper. The posterior extremity of the maxillary extending 
to a vertical line drawn altogether behind the entire orbit. The eyes are 
small. Dorsal fins not contiguous. Caudal posteriorly rounded. Extremi- 
ties of ventrals extending to the vent. Pectorals well developed. 
Log. — Specimens collected at Indianola, Texas, by John H. Clark, under 
Col. J. D. Graham. 
VII. GOBIOSOMA. — This genus is to include such species of the old genus 
Gobius, and which are deprived of scales : Gobius alepidotus, G. viridi palliduSj 
or G. boscii, belongs to this type. 
13. GoBiosoMA MOLESTUM. — Head large, depressed, constituting a little less 
than the fourth of the total length. Snout rounded ; jaws even ; posterior ex- 
tremity of maxillary reaching a vertical line drawn in advance of the pupil. 
Dorsal fins contiguous at their base. Caudal posteriorly rounded. Anal 
shorter than the second dorsal. Ventrals quite small, not extending to the 
vent. Pectorals broad and well developed, not extending beyond the ven- 
trals. 
Log. — From Indianola, Texas, collected by John H. Clark, under Col. J. D. 
Graham. 
14. Blennitjs multifilis. — Head contained four times and a half in the total 
length. Posterior extremity of maxillary reaching a vertical line drawn through 
the pupil. Four filiform cirrhi on either side. Spinous portion of dorsal fin 
lower and somewhat longer than the soft portion, which is contiguous to the 
base of the caudal. Caudal posteriorly rounded. Origin of anal situated in 
advance of the anterior soft ray of the dorsal. 
Log. — Specimens collected at St. Joseph's Island, Texas, by G. Wurjdemann. 
15. Eleoteis somnulektus. — Body subfusiform. Head contained abput four
