^faturae, and by Artedi, and that in the later editions, Linnaeus placed 

 that species at the head of the genus." For that reason, the name Uche- 

 7ieis was retained for E. rcmora, and a new name, Leptccheneis, conferred 

 on E. naucrates and its allies. 



As, however, according to the custom now prevalent in Ichthyology, 

 we are not to go behind the tenth edition of the Systema Natural, and 

 as the placing of a siiecies "at the head of the genus" had no signifi- 

 cance with Linntcus, we think that Dr. Gill's first restriction of Eche- 

 neis should have precedence over the second. 



The genera of EcJieneididw thus far known are, then, the following: 



1. Eemoea Gill: type Echeneis t'emora Jj.; EcJieneis jacoboea liowe. 



2. Remilegia Gill: type Eclieneis australis Bennett. 



3. RhojMBOCHIEUS Gill : type Eclieneis osteochir Cuvicr. 



4. EcHENEis Linn. : tyi^e Eclieneis nmicrates L. 



5. PH'i'HEmiCHTHYS Gill : type Echeneis lineatns Menzies. 



76. Echeneis naucrates L. 



Two specimens seen by Cones and Yarrow. 



Genus EEMOEA Gill. 



77. Remora jacobcea (Lowe) Gill. 



(Echeneis remora L.) 



Specimens seen by Dr. YaiTow, taken off Shackleford Banks. 

 SPHYR^NID^. 

 Genus SPHYE^NA Bloch. 



78. Sphyraena spet (Haiiy) Goode. 



Young specimens common in Beaufort Hai'bor. Our species is usually 

 called Sphyrccna horealis DeKay, without comparison with allied forms. 

 What fish DeKay had in mind is not clearly known. We identify our 

 Beaufort specimens with Sphyrccna spet [Esox sphyrccna L., Sphyrcena, 

 vulgaris Auct.), the common species of Eiu'ope and the Middle Atlantic. 

 Whether the West Indian 8. picuda also occurs northward, to help 

 form the dubious Sphyrcena borealis, is still uncertain. 



MUGILID^. 

 Genus MUGIL Linnaeus. 



79. Mugil brasiliensis Agasaiz. — White Mullet. 

 Very common in the harbor. 



80. Mugil plumieri Bloch. — Striped Mullet. 



The commonest food-fish of the North Carolina coast; everywhere 

 very abundant on the shoals in the harbor. 



Two species of Mugil certainly occur on our Atlantic coast, but they 

 have been confounded or misunderstood by nearly all Avriters except
