iu onr waters. ‘^Lamna 'punctata'’'’ Storer is doubtless based on Lamna 
cornubica, with which species Eafinesque’s description of Isurus ox- 
yrlujncJius is identified by Doderlein. This species should probably 
stand as I. spallanzanii Eaf. (Indice dTttiol. Sicil. 45, 1810^ 
Page 30. The reference to the generic description of Carcliarodon 
should be — 
(Smith MSS. ; Bonaparte, Mem. Soc. Neufch. ii, 9, 1339 : type Carchardon smithii Bon, 
= C. carcharias.) 
Page 30. Instead of C. rondeletii read : 
38. C. carcSiarias (L.) J. & G. 
To its synonymy add : 
(SqnaJus carcharias L. Syst. Nat. i, 400, excl. syn. pars: Carcharias verus Agassiz, 
Poiss. Foss, iii, 91, 1836.) 
Page 31. The reference to Cetorhhius should be — 
( “ Blainville, Bull. Soc. Philom. 1816, 1*21.”) 
Xo. 39 should be — 
39. C. maxiaiiss (Gunner) Blainv. 
and to the synonymy should be added : 
{^Squalns maximns Gunner, Trondj. Selskschr. iii, 33, 1765.) 
Page 31. The family RMnodontidcc and its species, Micristodus punc- 
tatus, should be omitted, as they do not belong within our faunal limits. 
Page 32. Instead of 31, GyropJeuroduSj read: 
31.— HETERODOA'TrS Blainville. 
(Blainville, Nouv. Bull. Scieuc. 1816, 121: type SquaJus x>hiUipi Lac.) 
The characters of the genus are equivalent to those of the family. The 
American species should staud as — 
41. II. francisci (Grd.) Gill. 
It is abundant on the coast of California from Point Concepcion south- 
ward. 
On page 37, instead of Pristis antiquorum, read: 
44. P. pectiaiatiis Latham. 
And read in the description, “rostral teeth in 25 to 28 pairs-’ (instead 
of 16 to 20, the number found iu P. antiquorum ; we find no authentic 
record of the occurrence of the latter species in our waters). P. pecti- 
iiatus occurs in the Tropical Seas, north to our South Atlantic coast; 
abundaut in the Gulf of Mexico; asceuding the Lower Mississippi.
