248 I'h'OCEEDINGS OF THE NATIONAL MUSEUM. vol. 50. 



If in head, ninth ray nearly 1. Second anal spine, 2h in head; first 

 ray about 1^. Caudal with median rays longest, slightly larger than 

 head; ventral spine, Ih, and first ray with filamentous end to second 

 anal ray base. Long falcate pectoral reaches caudal base. Color in 

 alcohol largely pale brownish; head and trunk everywhere tinged 

 with silvery-white. Iris whitish. Length, 140 mm. 



No. 12229, A. N. vS. P., type of Crypt-osmiUa Una Cope. S. 



Although described as 'everywhere uniform silvery" by Cope, 

 very slight indications of the darker transverse or vertical bands, 

 somewhat as figured by Pellegrin in his var. africana.,^ are evident. 

 This last was originally described by Osorio and appears in no way 

 to differ structurally from the above. Further comparison with 

 Philippine material, but slightly smaller, shows only a slight differ- 

 ence in scale structure or with usually 5 or 6 basal radii, while tiie 

 Liberian example has but 3 or 4 and usually 3.

Head, 3f ; depth, 2§; D. 54; A. 40; scales, 70 in lateral line to caudal 

 base and 6 more on latter; 21 scales above lateral line, 27 below; 

 snout, 3^ in head from upper jaw tip; eye, 6f ; maxillary, IJ; inter- 

 orbital, 2| in snout. Contour uniform ellipsoid. Caudal peduncle well 

 compressed; length, three-fourths its least depth or latter 2| in total 

 head length. Head width, 2f its length. Snout conic, broad as long. 

 Upper eye advanced for first third beyond lower. Mouth large, lower 

 jaw well protruded. Maxillary long, extends well beyond eye or about 

 three-fifths in head; expansion IJ in eye. Teeth long, slenderly 

 conic, in two rows with inner depressible inward, and all of larger 

 barbed. Interorbital level. Rakers, 14+20 short spincscent rudi- 

 ments; filaments, 1| in eye. Scales large, mostly cycloid; some 

 very weakly and sparsely ctenoid on left or colored side. Smaller 

 scales along body edges, and caudal very finely scaled. About 

 8 rows of scales on cheek; maxillary also scaly. Scales of colored 

 side with 40 radiating basal striae; same number but marginal on 

 pale side and very tine circuli incomplete. Lateral line midway 

 along side, inconspicuous. Dorsal origin eye-diameter behind lower 

 eye, twenty-third ray, 2^^ in head; thirteenth anal ray, 2f. Caudal
