Menidia peninsule atrimentis, new subspecies. 
Attention was first attracted to this form by a specimen from South Lake, near 
Indian River, having a peculiar Labidesthes-like appearance—long snout and slender 
form—but lacking the small scales of Labidesthes. Examination of all available 
specimens of Menidia from southern waters revealed similar examples, though not 
all so slender, from a number of localities in Florida. First, those from Lake Monroe 
which Goode & Bean included with M. peninsulae; from Lake Jessup, collected 
by R. E. Earll; then specimens from South Lake at Titusville, Fla., collected by 
Evermann & Bean; ‘‘Salt Lake,’’ near Tarpon Springs, Fla., collected by Evermann 
& Kendall, and from St. Johns River at Palatka, and from Lake Monroe, collected 
by the writer. 
Total length 2.5 inches; head in length to base of caudal fin 4; depth in same 
length 6; eye 2.88 in head; snout 3+ in head. D. v-i, 9; A. i, 15; scales 40-8. 
Very slender; lower jaw longer than eye; spinous dorsal wholly anterior to origin of 
anal, midway between tip of snout and base of caudal; base of anal much shorter 
than head, 5 in length of body, equal to distance from base of last rays of soft 
dorsal to base of upper rudimentary rays of caudal; height of soft dorsal 1.88 and 
anal 1.66 in head. Color in spirits, straw; scales of back thickly punctated with 
black on edges, giving the back a very dusky appearance; few black dots on the 
sides, not defining the edges of the scales; top of head, snout, and chin black, the 
black composed of fine dots. Lateral silver stripe overlying black. 
Menidia peninsulx atrimentis Kendall, new subspecies. 
This fish is much more slender than M. peninsulx, its nearest relative in southern 
waters; darker in color and found in waters more nearly fresh. It may be distin- 
guished by its slender form, really longer head and larger eyes, although the meas- 
urements of specimens of this species often show the same relative proportions, 
owing to the fact that many of the M. peninsule are young and these are more 
slender than the adults. There is considerable variation, and it seems to intergrade 
with M. peninsule, but has not been found to attain so large an adult size as the 
latter. It seems to be confined to fresh or nearly fresh water. The type (No. 50010, 
U.S. National Museum) is one of 33 specimens collected by Evermann & Bean in 
South Lake, Titusville, Florida, January 15, 1896. 
(ater, black; mentum, chin. ) 
Specimens from South Lake range in measurements as follows: Head 4 to 4.33, 
mostly 4; depth 5.66 to 6.25; eye 2.89 to 3.25, mostly 3; snout 3; D. v-i, 9 and 10; 
A. i, 16 to 18; scales 40 to 48. 
From Lake Monroe as follows: Head 4+ to 4.5; depth 5.5 to 7; eye 3; snout about 
3; D. 1v to vi-i, 9 to 11; A. i, 16 to18, mostly 17; scales 38 to 42. From Palatka, not 
essentially different from Lake Monroe specimens. 
From Salt Lake, near Lake Butler, Tarpon Springs, Florida, as follows: Head 3.8 
to 4, mostly 4; depth 5.25 to 6; eye 2.6 to 3, mostly 3; snout 3 to 3.25, mostly 3; D. 
Iv to vi-i, 8 to 10; A. 14 to 19; scales 36 to 40.
