378 Mr. 0. Thomas on 



interorbital region ; snout projecting beyond lower jaw ; eye 

 7 to 9 times in length of head, 2 to 2^ times in interorbital 

 width ; head-sliields all paired ; siiboperculum a little smaller 

 than eye. Dorsal with VII-VIII spines, anterior widely 

 separated when folded. Anal 12-13. Pectoral widely sepa- 

 rated from first dorsal spine. 56-59 scales in a longitudinal 

 series, 30-33 between occiput and first dorsal spine, 36-38 

 round middle of body. Dark olive above, yellow beneath, 

 back and sides spotted or marbled with blackish ; no large 

 black spot on the muscular part of the pectoral fin. 



Four specimens, measuring from 137 to 223 mm., were 

 obtained by Mr. Willonghby P. Lowe at Nanna Kru, Liberian 

 coast, in January 1911. 



P. lotvti is intermediate between P. palnias, Ayres (buetti- 

 koferij Stdr.), and P. retropinnis, Vaiil. It is readily distin- 

 guished from the first by the smaller eye and the higher 

 number of scales between occiput and dorsal fin (30-33 

 instead of 23-26), from the second by the lower number of 

 these scales and by the absence of a large black spot on the 

 muscular part of the pectoral fin. Besides, the snout of this 

 fish is broader than in either of the two species with which it 

 should be compared.
