[81] FLOUNDERS AND SOLES. 305 
We have not seen this species, and we take the above synonymy from 
Giinther. According to Dr. Day the name lascaris belongs to Solea 
aurantiaca. This species should stand in that case, perhaps, as Solea 
seriba. 
98. SOLEA THEOPHILA. 
Pleuronectes theophilus Risso, Ichth. Nice, 1810, 313. 
Pleuronectes nasutus Pallas, Zoogr. aaa a lil, 1811, 427. 
Solea nasuta Steindachner, l. ¢., 58. 
Solea impar Bennett, Phos. Gama Soc. Zool., i, 147,” 1831. Giinther, iv, 468. 
Habitat.—Mediterranean Sea. 
We do not know this species. According to Dr. Day it is identical 
with Solea aurantiaca, and should receive the name of Solea lascaris. 
Notwithstanding the close relation of S. theophila and S. aurantiaca, it 
would seem that the two are different, as the number of fin- -TayS iS con- 
siderably smaller in the present species than in S. aurantiaca, or than 
in the species called by us S. lascaris. 
The Italian naturalists should be able to settle these questions of 
synonymy. Judging from the literature alone, these three species 
would appear to be valid. S. aurantiaca would seem to be distinguished 
by the little development of its nasal fringes, its fin-rays being ‘‘ D. 81 
to 89; A. 66 to 68.” 8S. lascaris has the nostril with a wreath of fringes © 
and the fin-rays substantially similar, and S. theophila (=nasuta=impar) 
has the nostril well fringed and the fin-rays fewer; ‘‘D. 75 to 76; A. 
59 to 61.” 
Risso says of his Solea lascaris that its soieal rays are 85, anal 68. 
This agrees with our S. lascaris, which is that of Giinther, and differs 
from our theophila, the impar of Giinther, with which Day has identi- 
fied Risso’s lascaris. 
Risso further says that his Solea theophila (named for M. Théophile 
Rainaut, of Sospello) has 75 dorsal and 64 anal rays. This corresponds 
with the Solea impar of Giinther, and as the name theophila has priority 
over impar we have adopted it. Possibly all three are forms of a single 
species, Solea lascaris Risso. 
99. SOLEA VARIOLOSA. 
Solea variolosa Kner, Novara Fische, 1869, 289 (Rio Janeiro). 
Habitat.—Coast of Brazil. 
This species is known to us from the account given by Professor 
Kner.

(fide Bonaparte).
