PARALICHTHIN.^i 



Fig. 9: 



Known from 2 specimens, 127 and 200 mm. in total length, both collected by the 

 " Albatross " at Station 3368 (5° 32' 45" N., 86° 54' 30" W.). 



I am indebted to Mr. N. A. Borodin for sending me the gill-arch of one of these 

 specimens. This confirms my opinion that this species should be placed in the genus 

 Cyclopsetta. 



Genus 14. CITHARICHTHYS.

Close to Sy actum . Body ovate or rather deep. Eyes separated by a bony ridge 

 or concave space, which may be similar in both sexes or broader in the male. Olfactory 

 laminae in moderate number or rather numerous arranged transversely to or radiating

 moderate size, the length of the maxillary 2 to 3J in that of head. Gill-rakers short or 

 of moderate length, rather slender. Dorsal fin commencing on blind side of head, 

 above or just behind nostrils. Pectoral fins unequal, that of ocular side larger ; 

 upper rays usually not prolonged. Scales cycloid or feebly ctenoid. Vertebrje 33 

 to 40. 



Fourteen species from both coasts of America and from tropical West Africa.
