BOTHIDAE 133 



H. macrops, suggests that these are referable to Ginsburg's species. It seems probable 

 that //. mystacium occurs in the Straits of Magellan and on the southern part of the 

 Chilean coast, whereas H. macrops appears to be more northerly in its distribution.

 St. WS 742. 5. ix. 31. 38 22' S, 73° 41' W. Small beam trawl, 35 m.: 16 specimens, 50-190 mm. 

 Depth of body 2 to 2 \ in the length, length of head 3^ to 3^. Snout about as long 

 as eye (shorter in young), diameter of which is \\ to 5% in length of head and much 

 greater than interorbital width. 18 to 23 gill-rakers on lower part of anterior arch. 

 Scales ctenoid on ocular side, cycloid on blind side ; 85 to 97 in the lateral line. Dorsal 

 68-80 ; origin behind posterior nostril of blind side and above middle or anterior half 

 of eye. Anal 56-65. Pectoral of ocular side with 11 or 12 rays, length about J that of 

 head. Caudal peduncle \\ to i\ times as deep as long. Brownish or blackish, mottled 

 and spotted with darker; median fins blackish towards their margins; pectoral with 

 small dark spots. 



Hob. West coast of Patagonia; Chile. 



In addition to the above, there are 6 specimens (107-255 mm.) in the British Museum 

 collection, including the holotype of the species (Coppinger — 'Alert'), one from the 

 coast of Chile (Delfin), and 4 from near Concepcion (Cavendish Bentinck). 



I have hesitated to adopt the name kingii for this species, as Jenyn's species was 

 based upon a coloured sketch of a fish made by Captain King, an officer of the ' Beagle ', 

 and no specimen was preserved. The drawing shows the dorsal fin composed of two 

 portions, differing in structure, rather suggestive of a Psettodes, and there is no evidence 

 that it is intended to represent a species of Paralichthys. P. adspersus (Steindachner), 

 from the coasts of Chile and Peru, is very closely related to P. microps, differing chiefly 

 in the somewhat deeper body, more anterior origin of the dorsal fin, and the rather 

 lower number of gill-rakers.
