in onr waters. ^'■Lamna punctata^^ Storer is doubtless based on Lamna 

 cornuhica, with which species Eatinesqiie's description of Isurtis ox- 

 yrhynchus is identified by Doderlein. This species should probably 

 staud ns I. spaUanzanli Raf. (Indice d'lttiol. Sicil. 45, 1810). 



Page 30. The reference to the generic description of Carcharodon 

 shoukl be — 



(Smith MSS. ; Bonaparte, Mem. Soc. Neufch. ii, 9, 18:59 : type Carchardon smithii Bon. 

 = C. carcliarias.) 



Page 30. Instead of G. rondeletii read : 

 3§. C. carcBiarius (L.) J. & G. 

 To its synonymy add : 



(Sqxalus carcharias L. Syst. Nat. i, 400, excl. sijn. pars: Carcliarias verus Agassiz, 

 Poiss. Foss. iii, 91, 1836.) 



Page 31. The reference to CetorMnus should be — 

 ("Blainville, Bull. Soc. Philoni. 1816, 121.") 



No. 39 should be- 

 so. C liiaxaBlBiis (Gunner) Blainv. 



and to the synonymy should be added : 



{Squalns maximus Gunner, Troudj. Selskschr. iii, 3:1, 1765.; 



Page 31. The family EMnodontidw and its species, Micristodus punc- 

 tatMs, should be omitted, as they do not belong within our faunal limits. 



Page 32. Instead of 31, Gijropleurodus, read: 



31,— EaETEKOfi>0]\TUS Blainville. 

 (Blainville, Nouv. Bull. Scieuc. IBK!, 121: type Squalus phUlipi Lac.)

 41. H. francBSCB (Grd.) Gill. 



It is abundant on the coast of California from Point Coucepcion south- 

 ward. 



On page 37, instead of Pristis antiquorum, read: 

 44. P. pcctiaiatus Latham. 



And read in the description, "rostral teeth in 25 to 28 pairs" (instead 

 of IG to 20, the number found in P. antiquorum ; we fiud no authentic 

 record of the occurrence of the latter species in our waters). P. pecti- 

 natus occurs in the Tropical Seas, north to our South Atlantic coast j 

 abundant in the Gulf of Mexico; ascending the Lower Mississippi.
