178 FLATFISHES (HF.TEROSCIMATA) 



02-67 (6c)). Pectoral of ocular side with n to i [ rays, length i^ to 15 in that of head. 

 Caudal rounded. \'ertebr:e 10 -r 27-30. Brownish or greyish, with darker spots 

 and blotches, of which a patch just behind curve of lateral line and another on hinder 

 end of straight part are most prominent ; generally a narrow dark bar at base of 

 caudal fin : all the fins sprinkled with small dark spots ; often a dark spot distally 

 on fourth to sixth ravs of pelvic hn of ocular side ; first three or four dorsal rays 

 generally blackish in adults, but only the second ray is dark in immature specimens. 



Type. — British Museum (Nat. Hist.). Reg. No. qo.3,jo.i (lectotype). 



Distribution. — Mediterranean and Atlantic coasts of Ivuropc. northwards to 

 the British Isles : coasts of north-west Africa.

I (102 mm.). Dalmatia. Doria. 



In all the Mediterranean examples examined the second dorsal ray appears to be 

 much less broad and pinnate than in those from more northerly localities, but this 

 may be accounted for by the fact that the Mediterranean specimens have all been 

 preserved in alcohol, the others mainly in formalin. Kyle has pointed out that this 

 ray is very liable to damage, and its length is consequently very variable. 



In a letter dated January, 1933, the late Professor Johannes Schmidt points out 

 that Kyle has informed him that no type specimens were selected to represent this 

 and other new species and subspecies described in the report on the collections made 

 by the " Thor ". I have, therefore, chosen a well-preserved specimen in the British 

 INIuseum collection which will serve as a lectotype. 



Chabanaud (1931, 1933) has erected a new genus (Kyleia) for this species, distin- 

 guished from Arnoglossus by having the two interorbital ridges distinct and separated 

 instead of united As Bertin (i'i32) has recently pointed out, this genus cannot be 

 maintained.
