timious with that on tail. Median lateral ridge of trunk not con- 

 tinuous with upper lateral ridge of tail. Head width one-fourth its 

 length. Snout with least depth little nearer its tip than eye. Latter 

 ellipsoid, front pupil edge nearly midway in head length. Lower jaw 

 protrudes. Literorbital narrow or about half of ej^e-diameter, 

 deeply concave. Opercle with short ridge, little inclined from hori- 

 zontal, extends in front for about first fourth. Upper postocular 

 ridge not quite to occiput. Median occipital ridge, well developed, 

 extends back little beyond pectoral base or well over first body ring. 

 Greater part of dorsal fin on tail, or base on 4 trunk and 6 caudal 

 rings. Pectoral, 4^ in head; caudal, 3. Color in alcohol largely 

 uniform brownish; belly and lower surfaces of head and tail mostly 

 paler. Iris slaty. No markings. Length, 113 mm. 



Type.— No. 975, A.N.S.P. Gabun, West Africa. P. B. Du Chaillu. 



Also Nos. 976 to 978, A.N.S.P., paratypes. These show: head, 3 

 to 3} to vent; D. 35 to 37; rings, 18 to 20 + 37 or 38; snout, 2-^ to

2 J in head from upper jaw tip; eye, 2 to 2* m snout; length, 88 to 

 105 mm. 



This species appears unique in its advanced dorsal.

 in slight recognition of his studies on Gabun fishes.) 



ISCHNOMEMBRAS GABUNENSIS Fowler. 



Ischnomembras gabunensis Fowler, Proc. Acad. Nat. Sci. Pliila., 1904, p. 

 73, pi. 42. Gabun River. 



Two examples, the types, examined. D. One now in the Field 

 Museum at Chicago. 



LIZA RAMADA (Risso). 



Liza alosoides Fowler, Proc. Acad. Nat. Sci. Phila., 1903, p. 746, pi. 45. 

 Gabun River. 



Seven examples, the types of L. alosoides Fowler, examined. D. 



Boulenger's suggestion ^ of the identity of L. alosoides with the 

 present species is correct. A comparison of these types with the 

 Ashantee material noticed previously in these pages shows they are 

 nothing but young. They have the gill-rakers 22 + 28, but little less 

 than filaments, or 1 J m eye. The basal radii of the scales vary 6 to 9.
