227. Larimus argenteus {Gill). 



BOCATUERTA BLANCA. 



Very abundant. 



In this species, a vertical line from the corner of the closed mouth passes mid- 

 way between the front of the orbit and tiie tip of the snout. The length of the snout 

 is two-fifths that of the maxillary. The gape is arched, with the convexity behind. 

 The anterior (lower) margin of the mandible is also strongly arched with its convexity 

 forwards. The eye is smaller than in any other species of the genus, 4 J to 5 in head, 

 in adults. 



In life, very brilliant silvery on sides and below, the upper parts faintly olive, 

 with silvery, greenish and bluish reflections. The dorsal and anal are slightly dusky, 

 the pectorals translucent, the anal and ventrals white or faintly straw-colored. 



228. Larimus effulgens Gilbert. 



Plate XVI, Fio. 33. 



Larimus effulgens Gilbert (Jordan & Evermann, 1898, p. 1421). 



Very close to L. acclivis, with which it agrees in almost all details of structure. The color 

 is, however, bright silvery without trace of stripes, as in L. argenteus. The pectoral fin is ako much 

 longer. 



Dorsal XI, 28 to 30; anal II, 6; pectoral 16; head 2>^ss 'o 3l! depth 2j to 3; pores of lateral 

 line 49 or 50.
