DASYATIID^E. 



Urobatis jamaicensis (Cuvier). Round Sting-ray. 



Known from Garman's record of a foetus credited to New Jersey. 



Dasyatis centroura (Mitchill). Thorny Sting-ray. 



Atlantic (Atlantic City), Cape May, Monmouth (Ocean Grove and 

 Port Monmouth) Counties. 



Dasyatis hastatus (De Kay). Round Sting -ray. 

 Cape May County. Recorded by Baird and Bean. The examples I 

 recorded from Green Creek belong to this species, rather than D. cen- 

 troura. 1 Gebhard mentions 2 the species from New York Bay, and a 

 later reference 3 is based on a very early occurrence. 



Dasyatis say (Le Sueur). Say's Sting-ray. 



Atlantic, Cape May and Ocean Counties. Muller and Henle record 

 it from New York as Trygon sayi on Milbert's material. 4 It doubtless 

 occurs along the northern shores of New Jersey, as I have it from Barnegat 

 Inlet. 



Pteroplatea micrura (Schneider). Butterfly Ray. 



I have no material from New Jersey, though several times reported 

 from Cape May County (off Wildwood and in Delaware Bay). 



MYLIOBATIDjE. 

 Myliobatis freminvillii Le Sueur. Eagle Ray. 

 Cape May County. Frequent in mid and late summer. 



RHINOPTERIDJ3. 

 Rhinoptera bonasus (Mitchill). Cow-nosed Ray. 

 Atlantic, Cape May, Cumberland (off Egg Island), and Monmouth 

 Counties. 



MOBULID^e. 6 



Manta birostris (Walbaum). Manta Ray. 

 Cape May County. LeSueur and Mitchill, both in 1824, describe 

 it from "near the entrance to Delaware Bay." 



ACIPENSERID^. 

 Acipenser sturio Linnaeus. Sturgeon. 

 Atlantic, Burlington (Burlington, Dutch Neck fishery, Florence), 

 Cape May (Fishing Creek), Camden, Cumberland (Bay Side, Bridgeton), 



J Proc. Acad. Nat. Sci. Phila., 1909, p. 407. 



2 Ninth An. Rep. Reg. Univ. N. Y., 1856, p. 29. 



3 Forest and Stream, I, August 28, 1873, p. 40. 

 « Besch. Plagiost., 1841, p. 166. 



s Though Mobula hyposlomus (Bancroft) is not known from New Jersey, Garniau 

 gives its range as Brazil to New York. Possibly Cephaloptcrus vampirus De Kay, 

 Geol. Rep. N. Y., 1840, p. 31, from New York, may be M. hyposlomus.
