14 PROCEEDINGS OF THE ACADEMY OF [Jan., 



Gill-opening small, horizontal, well elevated and little before 

 pectoral origin, about long as pupil. 



Rings all firm, and keels each minutely serrate, each ending in 

 slight spine at sutures. Surface of each keel with many fine vertical 

 strise. 



Dorsal origin about opposite vent or about opposite beginning of 

 second section of upper lateral keel, and base extends over 9 abdominal 

 rings. Anal small, length about half of eye, and its insertion on first 

 abdominal ring slightly behind dorsal origin. Caudal small, oblong, 

 median ray longest. Pectoral very broad basally, so its base equals 

 eye-diameter, and length slightly less than its base. 



Color in alcohol rather dull brown generally, sides and belly 

 minutely dusted or speckled with dark brownish. Fom side of snout 

 end to eye deep brown streak, then this as well defined dark brown 

 line over postocular region, on side of back to caudal. Also on sides 

 below this dark line various dusky mottlings, most distinct on trunk 

 rings. Iris pale slaty. Fins largely colorless. 



Length 173 mm. 



Type, No. 47,485, A. N. S. P. 



Philippine Islands. Presented by the Commercial Museums of 

 Philadelphia. 



Allied with Microphis pleurostidus Peters, M. caudatus Peters and 

 M. jagorii Peters, all from the Philippines, but differs at once in the 

 much longer snout. 



Scomberoides tala (Cuvier). 



Five examples. Eleira Jordan and Seale, based on the present 

 species, does not appear really of generic rank. It is characterized 

 by the diverging front canine each side of the lower jaw tip. My 

 examples show this most pronounced in the young, and the teeth 

 gradually erect and inconspicuous with age. Young also without 

 black apical dorsal blotch. S. moadetta has enlarged front canines, 

 besides the black apical dorsal blotch. 



SELAB Bleeker. 



Selar Bleeker, Nat. Tijds. Ned. Indie, I, 1850, pp. 343, 352, 353. Type 



Caranx boops Cuvier, first species. 

 Trachurops Gill, Proc. Acad. Nat. Sci. Phila., 1862, p. 431. Type Scomber 



crmnenophthalmus Bloch, monotypic. 



The type of Selar has not been formally designated, so the above 

 may be adopted. Trachurops is thus superseded, as its type species 

 like that of Selar, has a deep cross-furrow at the shoulder-girdle at
