large as eye, with white center, dark iris, narrow, dark margin, and a brown en-

Habitat.—South Atlantic and Gulf coasts of the United States. 
This species is not rare along the South Atlantic and Gulf coasts of 
the United States. On referring the species to the genus Paralichthys 
it became necessary to change the specific name quadrocellatus, pre- 
occupied in the latter genus. We, however, now consider it best to 
retain Ancylopsetta as a group distinct from Paralichthys. 
22. ANCYLOPSETTA DILECTA. 
Notosema dilecta Goode & Bean, Bull. Mus. Comp. Zool., xix, 193, 1883 (Gulf Stream, 
off the coast of South Carolina). 
Ancylopsetta dilecta Jordan, Cat. Fish. N. A., 1885, 134. 
Paralichthys stigmatias Goode, Nat. Hist. Aquat. Anim., 1884, 182 (name only, by in- 
advertence for dilectus). 
Habitat.—Gulf Stream. 
This species is known from the original types obtained in the deep 
waters (75 fathoms) of the Gulf Stream, off the Carolina coast. 
Genus XII.—PHRYNORHOMBUS. 
Phrynorhombus Giinther, Catal. Fishes Brit. Mus., iv, 414, 1862 (wnimaculatus). 
TYPE: Rhombus unimaculatus Risso= Pleuronectes regius Bonnaterre. 
This genus is allied to Zeugopterus, from which it differs chiefly in the 
separation of the ventral and anal fins. It is, in our opinion, worthy 
of separation. Butasingle species is known. The peculiar flannel-like 
character of the scales is similar to that of Monochirus hispidus. 
ANALYSIS OF SPECIES OF PHRYNORHOMBUS.
