Page 379. Instead etf Exocoetus noveboracensis read: 
4509. E. roiideletii C. & V. 
The specimen described in the text came from the open sea, south of 
Newfoundland. The species is well distinguished from E. novebora- 
censis, by the black ventrals, the larger anal and shorter dorsal, the 
base of the anal being more than f that of the dorsal ; the head is 
blunt and the eye comparatively small ; dorsal beginning slightly be- 
fore anal; caudal large, its lower lobe half longer than head. D. 11 
or 12; A. 11 or 12 (not 9) ; Lat. 1. 42. New England to Mediterranean 
Sea. 
(Cuv. & Val. xix, 115; Giiuther, vi, 293.) 
Page 379. After Exocoetus rondeletii read: 
OlO. E. noveboracensis Mitchill. 
Dark bluish; pectorals blackish at tip, with a median whitish shade; 
ventrals white. Head rather slender, the snout not blunt; eye very 
large, 2| in head ; interorbital space rather narrow. Pectoral shorter 
and narrower than in E. rondeletii, barely reaching last ray of dorsal; 
first ray of jiectoral divided ; ventrals extending past anal, their inser- 
tion midway between preopercle and base of caudal ; dorsal beginning 
considerably in advance of anal, the length of its base more than twice 
that of anal; lower lobe of caudal not ^ longer than head. Head 4-|; 
depths^. D. 14; A. 9; Lat. 1. 45. Atlantic coast; specimens examined 
from Wood’s Holl and Pensacola. 
(Mitcliill, Amer. Monthly Mag. ii, 233, 1817; Dekay, New York Fauna, Fish. 230; 
C. & V. xix, 99: Exococlus mclanurus C. &. V. xix, 101.) 
Page 379. The description in the text of '■^E. melanurus^’ is taken 
from an adnlt example of E. exiliens, the young of which is described 
as E. exiliens on page 380. E. melannrus is therefore to be suppressed. 
E. exiliens is comparatively slender, the anal fin beginning opposite 
front of dorsal, its base f length of base of dorsal; lower caudal lobe 
short, shorter than head. D. 11; A. 12 (not 9, as erroneously stated in 
the text). 
Page 383. Instead of the foot-note add : 
«14 (6). S. affisae (Gthr.) J. & G. 
The specimen from St. John’s River, described in the foot-note on 
page 383, belongs to IS. affine. The bod 3 ’, in the female, is marked by 
silvery cross- streaks, which are very distinct in life. 
Page 384. In tS. lotiisiance i'\xQ rings are usually 20+38 in number; the 
dorsal raj's 32 to 35.
