inconspicuous,” color “greenish olive (in spirits)”; the color of another 
is “ greenish,” no mention of the eye ; another is “ rose-colored,” no men- 
tion of the eye, nor statement as to whether this is the color in life or in 
spirits ; a fourth is “ brownish with darker spots, . . . eye small and indis- 
tinct” ; another, “eyes invisible,” no mention of color. Of the remaining 
three, no mention is made of either the eyes or the color, but for the 
name in one species rubicundus is given as a synonym. Of the genus 
Trypauchen two species are described, one of which is characterized as 
“reddish (during life), brownish (in spirits),” the other as * uniform rose- 
colored." No mention is here made of the condition of the eyes, and I 
know them to be rudimentary only by the list of blind fishes given by 
the same author (Packard, ’86, p. 107). 
In the characterization of the genus Trypauchenichthys the eyes are 
” 
said to be “very small, scarcely visible,” and the only species described 
is “ rose-colored (Bl.).” Nothing is given to indicate that these fishes 
live particularly excluded from the light. The genus Amblyopus is said 
to be “confined to the coasts, estuaries, and fresh waters of the Fast 
Indies, extending northward to China and Japan ; one species from the 
west coast of South America.” The genus Trypauchen is from the “ Kast 
Indian Seas” and the “fresh waters of Borneo,” and Trypauchenich- 
thys is from “ rivers of Borneo.” 
We are not informed whether the several shades of red here men- 
tioned are due to pigmentation; but from the facts that there are 
several shades, that in some of the species the color seems to persist in 
the alcoholic specimens, and that the fishes come in a category many of 
which — particularly of the related genus Eleotris, with eyes normally 
developed, inhabiting much the same regions — are of similar shades of 
color, it appears probable that such is the case. 
Perhaps the most interest attaches to the color of the Mammoth Cave 
blind fishes and those of the caves of Cuba; for these are without any 
question completely deprived of the influence of light. Cope (’72, p. 410) 
speaks of Amblyopsis speleus as swimming “in full sight like white 
aquatic ghosts" ; in his original description of Typhlichthys subter- 
raneus, Girard (59, p. 63) gives its color as a “uniform dull yellowish 
white tint" ; and both these species as well as the Lucifuga are referred 
to by Putnam as being “nearly colorless,” as already mentioned.- Also 
Jordan and Gilbert (82) describe both Amblyopsis and Typhlichthys 
as “ colorless,” and in the same way Günther ('80, p. 618), who re- 
gards the two as belonging to the same genus, speaks of the body as 
colorless.
