 iostcjT'il iiK-mbraiu-s iinitcd at base for a very short distance. In four examples e.\amineti as to this 

 point, die ^ill-rakers are as follows: 20+25, 23+24. 21+23. '9+3°: ll>i" l"".i(est contained i^ to 

 1 1 in eye. Scales lari;e, thin, deciduous, a few only remaining,' on the s|)ecinH-ns at hand. Origin of 

 the dors;il tin equally distant from the base of the cauilal tin and the tip of snout or front of eye. Anal 

 insertetl under beginning of [wisterior third of b;ise of ilorsal. Pectorals not reaching ventrals, the 

 latter e.Ntending three-tifths distance to front of anal. 



Color light olive, with broad, well defined, lateral silvery streak of nearly uniform uidlh, 

 usually narrowing anteriorly and on middle of caudal ix;duncle, its width in our largest specimens (ive- 

 sixths diameter of eye. The silvery streak has a slight golden tinge. A narrow dark vertebral line, 

 which widens on the nape. Occiput blackish. 



This species differs from ./. ctiltrata in its slenderer body, shorter snout, wider opercle 

 and smaller teeth; the belly is also not sharjjly carinate, the dorsal is more anteriorly placed, 

 the ventrals are farther back, and tbe silvery streak is wider anteriorly. It differs from A. dclicatissima 

 in its longer, slenderer head and body, smaller eye, longer, sharper snout, and nuK-li u ider, better 

 defined silvery streak. 



Length 4 to (') cm. Named t'oi- Mr. Edwiti Cliapin Siarks. 



85. Anchovia panamensis {Sieindackiier). 



This species was found to be rather common. 



Dr. Steindachner seems to have had both A. panamensis and A. mundeola, as 

 his description covers both in many respects. His count of scales woiiki apply 

 better to .1. mundeola than io A. panamensis, which has 38 to 41. The length of 

 head, 4!, applies better to A. panamensis, that of A. mundeola being generally about 



I in liMigtli of body. Otherwise there seem to be no differences. 



86. Anchovia mundeola {Gilbert <t- Pierson). 



Stolcphorus mundcolus Gilbert & Pierson (Jordan & Evermann, 1898, p. 2812). 



Head 4.15 (4 to 4.25); depth 3.77 (3.40 to 4.25); eye 3.44 in head (3.12 to 3.70). Dorsal 

 13 or 14; anal 33 (33 to 35); scales 36 (36 to 39). Dorsal and ventral contours about equally and 

 gradually rounded from the middle region of body to the tip of snout and base of caudal fin. Snout 

 short, high, compressed, blunt at tip, its length i^ in eye. Eye very large. Maxillary broad, taper- 

 ing to a sharp point which reaches margin of gill-opening. Gill-rakers 17+21 to 22+24; the longest 



I I to 2 in eye. Anterior insertion of dorsal (in varying from a point midway between base of caudal 

 and middle of eye to a point midway between the caudal and tip of snout. In ten examples its inser- 

 tion is before that of the anal. Anal fin long, averaging 33 rays; its origin beneath the anterior thiril 

 of the dorsal; length of base shorter than in A. panamensis, being 3j'j in length, while in die latter 

 its length is contained 2\ in length. Pectorals long, reaching well beyond the insertion of the ventrals, 

 equaling length of head behind front of pupil; a large axillary scale. Ventrals scarcely reaching vent. 



Color uniformly light olive with silvery reflections; a faint, narrow, silvery stripe, .sometimes 

 scarcely distinguishable. Sides of head plain silvery. Upper margin of orbital rim black. Dorsal 

 region blackish. A faint, narrow, dark line on each side of the light mid-dorsal streak. Caudal 

 slightly dusky. Fins otherwise unmarked. 



This species is closely allied to A. panamensis and A. compressa, but may be distin- 

 guished from the former by its longer head, larger eye, greater depth, fewer scales along the lateral 

 line, and its much shorter anal base; also by the much fainter lateral silvery stripe. The eye is con- 

 tained 14 to 16 times in length, excluding the caudal; while in panamensis the length contains the eye 

 16 to 20 times.
