39. Sciaenops ocellatus (Linn.) Gill. — Red Horse; Channel Bass. 



A single specimen, No. 21,774, 15^ inches long. D. X, I, 24; A. II, 

 7 ; P. II, 14 ; V. I, 5 ; C. 17. L. lat. 46 ; L. trans, h- ^our black spots 

 on the right side ; two on the left. 



40. Menticirrus alburuus (Linn.) Gill. — Wlviihig. 



A single specimen, No. 21,332 (34), 15 inches long, in color silvery- 

 white immaculate, with bluish reflections upon back and body, white 

 upon the belly. 



In coloration, this specimen agrees with the Menticirrus Uttoralis of 

 Holbrook, but seems to have no definite characters by which it may be 

 distinguished. 



D. X, I, 24; A. I, 6^; P. 20; V, 6; C. 17. L. lat. about 60; L. 

 trans, if. 



Another specimen. No. 22,832, 9^ inches long, agrees in i^roportions 

 with the above. Its color is, however, very dusky, and the cloudings are 

 blackish. 



D. IX, I, 24 ; A. I, 7 ; P. 19 ; V. I, 5. L. lat. 70 ; L. trans, ii. 



41. Micropogon undulatus (Linn.) Cuv. & Val. — Croalcor. 



A single specimen, No. 21,479 (37), about 5 inches long. D. IX, 

 I, 28 ; A. II, 71 ; P. 18 ; V. I, 5 ; C. 9 + 8. L. lat. 72 or 73 ; L. trans, if. 



20. GERRID^. 



42. Euciuostomus harengnlus sp. nov. Goode & Bean. 



There are in the collection two specimens of an undescribed Eucino- 

 stonms collected in West Florida by Kaiser and Martin. The catalogue 

 number of the specimens is 5145. The largest is 120 millimetres in length 

 to the origin of the middle caudal rays ; the smaller, 87 millime- 

 tres. The species may be briefly characterized as follows : D. IX, 10 ; 

 A. Ill, 7 ; P. 15 ; V. I, 5 ; C. +17+. L. lat. 44 ; L. trans. ^%. 



The height of the body is contained 3 to 3^ times in the total length 

 without caudal ; the length of the head, 3^ to 3J times ; the diameter 

 of the eye exceeds the length of the snout, and is contained 3 times in 

 the length of the head, and equals the width of the interorbital space. 

 The groove for the processes of the intermaxillaries is naked, and ex- 

 tends to the vertical through the anterior third of the eye. The free 

 portion of the tail is longer than high. The lej^st height of tail equals 

 the length of the 6th dorsal spine. The 3d dorsal spine is the longest, 

 its length being contained twice in the height of the body, and equals 

 the length of the head without the j^ostorbital portion ; the last dorsal 

 spine equals in length the 2d anal, and about equals the length of the 

 snout, and is about f as long as the 3d. The 1st dorsal ray is fully 

 1^ times as long as the 1st dorsal spine. The 2d anal sjiine is 

 stronger and shorter than the 3d, its length being contained 3f times 

 in the length of the head. The 3d anal spine is contained 3:V times in 

 the length of the head. The caudal is forked, its length slightly less
