130. SYMPHURUS ATRICAUDA. 
Aphoristia atricauda Jordan & Gilbert, Proc. U.S. Nat. Mus., 1880, 23 (San Diego). 
Jordan & Gilbert, Synopsis Fish. N. A., 1882, 842. Jordan & Gilbert, Proc. 
U.S. Nat. Mus., 1882, 380. (San José, Lower California.) Jordan, Proc. U.S. 
Nat. Mus., 1886, 54. 
Habitat.—Lower California, north to San Diego. 
This species is common inthe bay of San Diego, in which locality the 
numerous specimens before us were taken. A small specimen 14 inches 
long, with light spots on the colored side and a pale ocellation on the 
black of the tail, taken by Mr. L. Belding near Cape San Lucas, prob- 
ably belongs to the same species. 
Symphurus atricauda is very close to S. elongatus, and both might well 
be regarded as geographical varieties of S. plagusia.

The numerous specimens of this species examined by us are from Ha- 
vana, Pernambuco, Santos, Rio Janeiro, Curuga, and Victoria. 
The synonymy of this species is somewhat doubtful. The original 
type of Pleuronectes plagiusa was sent to Linnzeus by Dr. Gardena, of 
Charleston. It would therefore appear probable that this specimen 
represented the species of this genus which is found on the Carolina 
coast. But this typical specimen is still preserved in the rooms of the 
Linnzan Society in London, where it has been examined by Goode 
and Bean. 
From their notes (Proc. U. 8. Nat. Mus., 1885, 196) we quote: “ The 
type of this species may have come from Africa or India. There is con- 
siderable doubt as to its origin. (See Garden’s Correspondence with 
Linné, page 314.) D. ca 92, A. ca 50. Seales 77. The species is more 
elongate than our specimens of Aphoristia plagiusa, so called, the depth 
being contained in the total length without caudal 44 times and the 
head 6 times.” 
As, however, no species of this genus are yet known from Africa or 
India, it is rather probable that Garden’s fish actually came from —
