GILBERT AND STARKS — FISHES OF PANAMA BAY 



47 



Owing to the action of formalin, these specimens have little of their original 

 color left. Where scales remain, the lower parts of the sides are bright silvery, 

 rather abrnpth' shaded to olive above. Apparently no lateral stripe was present. 

 The caudal and the first rays of dorsal arc tipped with black. In life, the caudal and 

 dorsal were otherwise bright yellow. 



Measurements in Hundredths of Length to Base of Caudal. 



88. Anchovia macrolepidota (Kner li- Sieindachner). 



Very abundant, reaching a large size and used for bait. The body is closely 

 compressed, and very minute teeth persist in the maxillaries even in adults. 



89. Cetengraulis mysticetus Ghnlher. 



Abundant; often used as bait in hand-line fishing. It reaches a length of 

 20 era. Our specimens have been compared with C. edentulus from Jamaica, and 

 are found to difler from this closely related Atlantic representative in the sliglitly 

 longer head, slenderer body and caudal peduncle, smaller eye, and shorter anal fin. 

 The anal has an average of but one less ray, instead of three less, as given by Jordan 

 & Evermann, 1896, p. 450. 



In the original description, the gill-rakers on the lower part of arch are said 

 to number 42. Dr. Boulenger has kindly reexamined for us the three types in the 

 British Museum, and finds in each from 55 to GO gill-rakers. The number in the 

 specimens at hand ranges from 53 to 66. In these specimens, the pectorals usually 

 do not reach the ventrals, either terminating some distance from them, or rarely 

 approximating them. 



The color in life is light olivaceous or olive-green above, passing into 

 the bright silvery of sides and lower parts. No lateral stripe. Caudal margined 

 with dusky.
