rim and placed about midway in snout in profile view. Posterior nos- 

 tril larger, high, somewhat slit-like and about opposite upper anterior 

 orbital margin. Interor]:>ital space broad and flattened, or but slightly 

 convex. 



Gill-opening extending forward till nearly opposite first f of orbit. 

 Rakers 40??, slender, fine, rather short, or about half length of filaments. 

 Filaments long, about | of orbital diameter. Pseudobranchise about 

 y of orbit. Isthmus narrow, with a median groove. 



Stomach gizzard-like, muscular, about equal to orbit in size. Intes- 

 tine rather long and convoluted. Peritoneum black. Vent close in 

 front of insertion of anal fin. 



Scales large, with finely ciliated edges, and in more or less even longi- 

 tudinal series. Head scaly. Opercles at present naked. Scales on 

 snout small. A pointed scaly flap at base of spinous dorsal equals 

 about ^ length of first spine. A similar scaly flap in axil of pectoral 

 equal to about | length of fin. Ventral also with a similar flap equal 

 to about f length of fin, and a broad one between bases of fins which is 

 damaged. Greater portions of soft dorsal, anal and caudal covered 

 with minute scales, those about bases of fins larger. 



Spinous dorsal inserted much nearer base of caudal than tip of snout, 

 first spine enlarged and longest, and others graduated down. Soft dor- 

 sal inserted well behind origin of anal or much nearer base of caudal 

 than origin of spinous dorsal, and first ray highest. Anal similar, first 

 spine short, third longest and second but little shorter than third. 

 First anal ray longest. Caudal small, broad, and a little emarginate. 

 Pectoral small, and its insertion a little above middle in vertical orbital 

 diameter. Ventral inserted a little before middle of de])ressed pectoral, 

 and spine about equal to f length of fin. 



Color in alcohol brownish, and everywhere more or less silvery. 

 Back and upper surface brownish. Fins all pale brownish, dorsals and 

 caudal a trifle darker. Eye brassy-white. 



Length about 3 inches. 



Six examples, the one descril^ed above largest. Day's figure" 

 shows a higher spine to second dorsal than that found on any of my 

 examples. 



SCOMBRID^. 

 54. Scomberomorus guttatus (Schneider). 



Differs but little from Sumatran examples. Teeth about 31 in upper 

 jaw and about 34? in lower. Color faded so that spots are diffuse and 

 indistinct. Caudal whitish. One example, Uf inches.
