granular, blunt, conical, or rounded, those on maxillaries in bands 

 of four somewhat irregular rows; those on intermaxillary plate 

 much larger, about a dozen in 

 my examples but often more nu- 

 merous and forming a large oval 

 group of very coarse teeth; vo- 

 merine teeth continuous with 

 those on intermaxillary, form- 

 ing a long four-rowed band ex- 

 tending farther back than those c ° s ° 

 in jaws; teeth on mandibles in FlG ch ^ ar 

 bands of two rows, becoming P ia te ; 

 three rowed and coarser at sym- bIes - : 

 physis. The teeth in older specimens are much coarser and the 

 bands wider than in the younger ones, so that there is great 

 variation. 



Four pairs of conspicuous pores on snout, the last opposite 

 middle of eyes ; similar pores on upper lip and curving up 

 around eye; a row on lower jaw and two behind and a little 

 below rictus ; origin of lateral line far forward, on occiput. 



Color of alcoholic specimens a dark leaden hue above, merging 

 into pale, almost white below, everywhere densely punctulate 

 with myriads of fine dark dots; also blackish brown above, ( 

 lighter below. 



Here described from two specimens, 513 and 598 millimeters 

 long, in the Bureau of Science collection, collected at Alammos, 

 Pangasinan Province, through the kindness of Mr. Eugenio 

 Fenix. I have also seen a very fine specimen in the Santo 

 Tomas museum, having a length of 705 millimeters, which was 

 obtained from Manila Bay. This species has been recorded from 

 "Zebu" (Cebu) by Gunther and from "the Philippines by 

 Fowler. , _, .. . ., 



Since this went to press Chaplain Joseph Clemens collected a 

 fine specimen, 780 millimeters long, at San Fernando, Pam- 

 panga, and I obtained one at Vigan, Ilocos Sur, 1,035 millimeters
