[81] FLOUNDERS AND SOLES. 305 



We Lave uot 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 

 8criba. 



98. SOLEA THEOPHILA. 



1'kttroncctvs theophilm Kisso, Ichth. Nice, 1810, 313. 



Pleuroneetes nasutus Pallas, Zoogr. Rosso-Asiatica, iii, 1811, 427. 



Solea nasuta Steindachner, 1. c, 58. 



Solca impar Bennett, "Proc. Comoi. 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 Solca 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-rays 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. SL 

 to 89 ; A. 66 to 68." S. 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." 



Eisso says of his Solea lascaris that its dorsal rays are 85, anal 08. 

 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 Eisso's lascaris. 



Eisso further says that his Solea theophila (named for M. Theophile 

 Eainaut, of Sospello) has 75 dorsal and 64 anal rays. This corresponds 

 with the Solea impar of Giinther, and as the name tlieopliila has priority 

 over impar we have adopted it. Possibly all three are forms of a single 

 species, Solea lascaris Eisso. 



99. SOLEA VARIOLOSA. 



Solea variolosa Kuer, Novara Fische, 1869, 289 (Rio Janeiro). 



Habitat. — Coast of Brazil. 



This species is known to us from the account given by Professor 

 Kner.
