p. 25 — Key West, Florida. 



The nominal species stolifera was described by Jordan and Gilbert as differing 

 principally in the number of dorsal and anal rays; as the authors stated, "We 

 should identify our specimens with Clupea lamprotaenia Gosse, from Jamaica, 

 were it not for the difference in the number of fin rays." Beebe and Tee-Van 

 (Zoologica, vol. 10, 1928, p. 44) already have pointed out that in specimens from 

 Haiti the fin-ray counts come within the range of either species, the range given 

 by them being 11 to 13 rays for the dorsal and 14 to 17 for the anal. In 44 speci- 

 mens from Tortugas the range is extended still farther, as 9 to 12 rays have been 

 counted in the dorsal and 11 to 16 in the anal. In 3 specimens from Key West, 

 the type locality, we count 12 and 13 rays in the dorsal, whereas the type was 

 described as having 11 rays; and the anal has 14 or 15 rays instead of 17 in the 

 type, which upon re-examination, however, appears to have only 15. The rays 

 sometimes are difficult to enumerate, and therefore the wide range may result in 

 part from errors in counting. 



The depth also is variable, as in 17 specimens from Tortugas the greatest depth 

 is contained from 5.3 to 6.8 times in the standard length; diameter of eye equal 

 to or more usually a little greater than length of snout, being contained 2.75 to 

 3.3 times in head; origin of dorsal sometimes equidistant from tip of snout and 

 base of caudal, but oftener nearer the former; ventrals inserted somewhere under 

 base of dorsal, usually under 4th to 8th ray. The range in the fin-ray counts and 

 proportions, then, is such that the supposed differences between lamprotaenia 

 and stolifera are blotted out. Therefore, we confirm Beebe and Tee-Van's 

 (Zoologica, vol. 10, 1928, p. 43) finding, namely, that stolifera is a synonym of 

 lamprotaenia, a decision arrived at also by Parr (Bull. Bingham Oceanog. Coll., 

 vol. 3, art. 4, 1930, p. 3). 



Dr. Longley's notes state: "Exceedingly common at Tortugas, particularly 

 along shore, where predacious fishes often drive them too close for safety, and 

 large numbers are cast upon the windward beaches to spring about until a wave 

 rescues them, or until they perish. 



"The color is faintly greenish dorsally and the sides have a distinct lateral 

 silvery band."
