Page 117, C. discobolus, Table 21, Postflexion Mesolarvae: update all yolk-related characters
with "j" (superscript i) in column for mean values, and add footnote "iRare 14-mm-SL
specimens have been observed with some remnant yolk." below table.
Page 119, C. discobolus, Fig. 45, ventral view: correct to indicate presence of beginning pelvic
fin buds located as per lateral view.
Page 120, C. discobolus, figures: correct by reversing drawings such that the lower drawing
becomes Fig. 46 and the upper drawing becomes Fig. 47.
Page 124, C. latipinnis, Table 24: update yolk assimilated to "(14)15(16)" mm SL and
"(15) 16-17" mm TL and principal caudal fin rays last formed to "(14) 15(16)" mm SL
and "(15)16(17)" mm TL. (Based on mesolarvae collected from the Yampa River in
1976 and 1977-LFL# 69949, 69951, 69952, 69975.)
Page 125, C. latipinnis, Table 25: update transition to postflexion mesolarva to "(14)15(16)" nun
SL and "(15)16(17)" mm TL. (Based on mesolarvae phase collected from the Yampa
River in 1976 and 1977-LFL# 69949,69951,69952,69975.)
Page 125, C. latipinnis, Table 26, Flexion Mesolarva: update minimum values for yolk length
and maximum yolk depth and width with "l"(superscript letter 1) and add footnote <dactual
minimum is zero based on observation of specimens as small as 14-nun SL without yolk"
to bottom of table.
Page 127, C. latipinnis, Fig. 59, ventral view: correct to indicate presence of beginning pelvic fin
buds located as per lateral view.
Page 133, C. platyrhynchus, Table 3, Flexion mesolarvae: correct missing data by adding "54:1:1C
53-54" for Length (%SL) AS to OP2, "50:l:0c 50-50" for Length (%SL) AS to OD, "O:l:Oc
0->0" for Length (%SL) P2, "21:1:1c 20-21" for Myomeres to OP2, and "19:1:1 C 18-19"
for Myomeres to OD.
Page 138, C. platyrhynchus, figures, middle and bottom photographs: correct by reversing left-
right locations such that those on right become corresponding parts of Fig. 78 and those
on left become corresponding parts of Fig. 79.
Page 140, X texanus,Table 34: update formation of pelvic fin buds to "(13)14" mm SL, dorsal
fin rays first formed to "13-14" mm SL and "(14)15" mm TL, anal fin rays first formed
to "(13-)15" mm SL and "(14-)17" nun TL, pectoral fm rays first formed to "(13-)15"
mm SL and "(15-)17" mm TL, and pelvic fin rays first formed to "(13-)15-17" mm SL
and "(15-)18-20." (Based on observations by Martinez 1996 and, for pelvic fin buds and
dorsal fin rays first formed, on a specimen collected from the San Juan River in 200 1 and
maintained by the Museum of Southwest em Biology-Accession# 2001-IV:17,
Collection# WJBOI-134.)
Page 141, X texanus, Table 35: correct transition to flexion mesolarva to "(10)11(12)" mm SL
and transition to postflexion mesolarva to "(11)12-13" mm SL.
