' BcFostoma should probably be re^^arded as a subgenus of Achirus rather than as a 

 distinct genus. Auioug the numerous species, the pectoral of the right side is found 

 in every degree of development. In some species, a small pectoral is found on tRe 

 left side in some specimens, while it is wanting in others. Still other species have 

 also two pectorals developed.

■* Achirus iuscriptus Gosse. 



Olivaceous, covered with an irregular network of blackish lines; this network 

 rather finer on the head ; some specimens crossed by irregular but nearly straight 

 vertical lines ; others without traces of these ; dorsal and anal colored like the body^ 

 rather darker, with a paler edge; caudal abriaptly whitish, innnaculate; blind side 

 immaculate, darker on the fins ; hair-like appendages whitish ; scales about head 

 enlarged and fringed, especially on blind side ; lip of eyed side nnich fringed ; inter- 

 orbital width less than eye ; upper eye slightly in advance of lower ; right pectoral 

 of three rays, the middle one somewhat longer than the others ; left ventral of one or 

 two very small rays often entirely absent ; right side with scattered cilia, which are 

 mostly whitish ; ventrals .5- rayed, the right ventral joined to the anal; head, 3f; 

 depth, If ; D., 54 ; A., 40 ; lat. 1., 75 to 80. West Indies, north to Key West.

 ther, IV, 472 ; Achirus inscriptus Jordan, Proc. U. S. Nat. Mus., 1884, 143*) 



5 The name Pleuronec>es achirus L. (Achirus fasciatus Lac.) was based on specimens 

 from Surinam ; the name Pleuronectes Imeatus on the figures of Brown and Sloane of 

 fishes from Jamaica. If, therefore, the West Indian form is considered distinct from 

 the northern one, the former must be Achirus achirus or Achirus lineatus, and the latter 

 must take Mitchill's name, ^'mollis." If considered as varieties of one species, the 

 West Indian form has the prior names. 



^Aphoristia uebulosa Goode & Bean. 



Grayish, everywhere mottled with brown ; median keel on each scale dark and 

 prominent. Body comparatively slender ; scales small, rough ; jaws and snout naked ; 

 interorbital space with one row of scales. Teeth small, apparently equally developed 

 on both sides. Ventral well separated from anal, its longest ray 3 in head. Head of; 

 depth 4|, D. 119, A.107, P. 0. V. 5. Scales 120-50. L. 3i inches. Gulf Stream, oflf 

 the coast of Carolina. (Goode tf- Bean.)
