904- CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY IV. 



Page 379. Instead of Exocoetus noveboracensis read: 



609. E. rondeletii C. & V. 



The specimeu described iu the text came from the opeu sea, south of O 

 Newfouudlaud. The species is well distinguished from E. novebora- 

 censis, by the bhick veutrals, 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.

Page 379. After Exoccetus rondeletii read : 



610. E. uoveboracensis Mitchill. 



Dark bluish; pectorals blackish at tip, with a median whitish shade; 

 ventrals white. Head rather slender, the snout not blunt; eye very 

 large, 2f iu head ; interorbital space rather narrow. Pectoral shorter 

 and narrower than in U. rondeletii, barely reaching last ray of dorsal; 

 first ray of pectoral divided ; ventrals extending past anal, their inser- 

 tion midway between preopercle and base of caudal ; dorsal beginning 

 considerably iu advance of anal, the length of its base more than twice 

 that of anal; lower lobe of caudal not ^ longer than head. Head 4§; 

 dei)th54. D. 14; A. 9; Lat. 1.45. Atlantic coast; specimens examined 

 from Wood's Holl and Peusacola.

 C. & V. xix, 99: Exoccctus mclanurus C. &. V, xix, 101.) 



Page 379. The description in the text of "J?, melamirus^^ is taken 

 from an adult example of U. exiliens, the young of which is described 

 as E. exiliens on page 380. E. melamiriis 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: 

 614 (&). S. nffinc (Gthr.) J. & G. 



The specimen from kSt. John's Kiver, described in the foot-note on 

 page 383, belongs to >S. affine. The body, iu the female, is marked by 

 silvery cross-streaks, which are very distinct in life. 



Page 384. In S. louiHanw the rings are usually 20+38 in number; the 

 dorsal ravs 32 to 35.
