Family CARCHARIID^. 



2. GALEOCERDO TIGRINUS Miiller and Henle. 



Galeocerdo raynerl Macdoxald and Barron, Proc. Zool. Soc, 1868, p. 368, pi. 

 XXXII, not Galeus niactdatus Ranzani of the Atlantic. 



One large specimen, answering well to the description and figure 

 given by ]Macdonald and Barron, except that the coloration is brighter, 

 the black spots along the base of the dorsal being bright, and the 

 short, black, vertical bands below them conspicuous. A stuffed speci- 

 men from Nagasaki, called Galeocerdo ttgrittus by Jordan and Fowler" 

 although faded, shows the same color markings. 



It seems certain that the original Galeocerdo tlgrinus of Midler and 

 Henle, from Pondicherry, i,^ the same species, and that the species 

 with spots, instead of vertical bars l)elow the dorsal, Galeocerdo macu- 

 latm (Ranzani), is probably confined to the Atlantic. 



Family OPHICHTHYID.E. 



3. MICRODONOPHIS FOWLERI Jordan and Evermann. 



4. BRACHYSOMOPHIS HENSHAWI Jordan and Snyder, new species. 



Head measured to gill opening, 7.5 in length, 'd.'S in length to vent; 

 depth 2.5 in head; ej^e 1.5 in snout; snout 10 in head. 



Body cylindrical, the head greatly depressed, swollen laterally in 

 the region of the occiput, narrowing anteriorly to the pointed snout; 

 a conspicuous transverse depression in the post-orbital region; inter- 

 orbital space concave, its width equal to length of snout; a slight 

 supra-orbital crest, ending in a prominent wart-like protuberance 

 behind eye. Nostrils wdth minute tubes, the anterior located midway 

 between tip of snoitt and eye, the posterior on lip between eye and 

 anterior nostril. Mouth large, length of cleft contained 2.8 in head; 

 lower jaw projecting beyond the upper; outer edge of lips with a row 

 of rather coarse papilla\ Teeth of upper jaw in two rows, the outer 

 ones small and close set, the inner ones larger; vomer with a single 

 row of five or six widely-spaced canines, the anterior of which is about 

 equal in length to diameter of eve, the others growing successively 

 smaller; tip of jaw^ with three minute teeth separated from the lateral 

 rows by a wide space; lower jaw with a single row of widely-spaced 

 fang-like teeth. Teeth all sharply pointed; many of them in both 

 jaws depressible. No tongue. Gill openings below middle of body, 

 their length equal to width of space between them or to distance 

 between tip of snout and posterior border of eye. 



One-fourth of base of pectoral above gill opening; length of pec- 

 tofalequal to distance between tip of snout and center of pupil. Dor-
