each scale is angulated behind. Soft dorsal naked. Head 4^; depth 6. 

 D. IV or V-I, 8 or 9; A. 1, 17 or 18; scales 45-10. L. 3 inches. Missis- 

 sippi Kiver; the types from Memphis and Vioksbnr^-. {Hay MSS.) 



Page 408. Under M. bcryUina read " two lialf-row of scales,'* instead 



of "2^." 



Page 408. Instead of Menidia brasiUensis read : 

 644. M. bO!$ci (Ciiv. & Val.) Swain. 



Distinguished from M. notata by the deeper body and stronger teeth. 

 The soft dorsal and anal, as in other smooth-scaled species, are free from 

 scales. D. IV-I, 8"; A. usually I, 24. South Carolina to Florida.

Page 415. The genus and species '•'- Argyrotwnia vlttata^'' should be 

 erased from the system. We ha\ e little doubt that they are based on 

 a specimen of Ammodytes americanus. Our alleged species of Ammo- 

 dytidw are perhaps all forms of Ammodytes tobianvs L. A. persotiatus, 

 at least, is not distinguishable from A. americanns. 



Page 417. To the synonymy of Ucheneis remora add: 



(Echeneis squalipeta Daldorf Nat. Selskab. ii, If)?, about 1785; and Giinther ii, 157. 

 If the subgenus Remora Gill, be adopted as a genus, which may be desirable, this spe- 

 cies should stand as Remora ftqualipeta (Dald.) J. & G.) 



Page 418. Elacate Canada is known in Florida as " Sergeant-fish," from 

 its lateral stripes ; also, as "Snooks" and "Ling." 



Page 420. Instead of Tetrapturus albidiis read: 

 663. T. indiciis C. & Y. 



Tropical seas, northward to the Grand Banks, on our Atlantic coast. 

 Instead of the synonymy in the text, substitute the following:* 



(C. & V. Hist. Nat. Poiss. viii, 1831,286: Tetrapturus herschelii Gray, Ann. Nat. Hist, 

 i, 313,, 1838 : Tetrapturus herschelii Liitken, Spolia Atlantica, 1880, 441 : Histiophorus her-

 & Schneider) Goode, a distinct species, known only frona the Mediterranean.) 



*This synonymy is given in accordance with the views of Dr. Liitken, who recog- 

 nizes but live species oi Xiphiidce. This view is probably correct but, as has been per- 

 tinently ol)Herved by Professor Goode, the identity of the American species called 

 Tetrapturus alhidus and Histiophorus ama'uamis, with their Old World representatives, 

 is yet unproven, and in many respects it is desirable to retain the Ann!rican names until 

 this identity is shown. " To unite species from widely distant localities, without ever 

 having seen them, is very disastrous to a proper understanding of the problems of 

 geographical distribution." (Goode, Proc. U. S. Nat. Mus. 1881, 427.)
