ADDENDA 72. XIPHIID^E TETRAPTUKUS. 909 



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

 D. IV or V-I, 8 or 9; A. 1, 17 or 18 5 scales 45-10. L. 3 inches. Missis- 

 sippi Eiver; the types from Memphis and Vicksburg. (Hay MSS.) 



Page 408. Under M. leryllina read " two half-row of scales," instead 

 of. "2." 



Page 408. Instead of Menidia braslliemis read : 

 644. Itt. foosci (Cnv. &. Val.) Swain. 



Distinguished from If. 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, 



(Atherina menidia L. Syst. Nat. : A. losci C. & V. X, 465; not A. Irasiliensis Q. & G.) 



Page 415. The genus and species " Argyrotcvnia vittata" should be 

 erased from the system. We have little doubt that they are based on 

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

 dytidce are perhaps all forms of Ammodytes toblanus L. A. personatusj 

 at least, is not distinguishable from A. americanus. 



Page 417. To the synonymy of Eclieneis remora add: 



(Echcneis squalipeta Daldorf Nat. Selskab. ii, 157, about 1785; and Giiuther ii, 157. 

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

 cies should stand as Remora squalipeta (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 albidus read: 

 663. T. indicus C. & V. 



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, 1331,286: Tetrapturus hersclielii Gray, Ann. Nat. Hist, 

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

 schelii Gunther, ii, 513 : Tetrapturus albidus Poey, Me"m. Cuba, ii, 237, 1858: ? Tetraptu- 

 rus ampins Poey, Me"m. Cuba, ii, 243 : Histiophorus brevirostris Gthr. and Playfair. Fish. 

 Zanzibar, 1866. 53: Tetrapturus geortjii Lowe, Proc. Zool. Soc. Lend, viii, 36, 1840: Te- 

 trapturus lessonii Canestrini, Arch. Zool. i, 259, 1861 ; Goode, Proc. U. S. Nat. Mus. 

 1881, 418 (detailed review of family) : not Tetrapturus belone Raf.=T. im-perator (Bloch 

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



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

 nizes but five species of XipTiiidce. This view is probably correct but, as has been per- 

 tinently observed by Professor Goode, the identity of the American species called 

 Tetrapturus albidus and Histiopliorus americanus, with their Old World representatives, 

 is yet unproveu, and in many respects it is desirable to retain the American 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.)
