<br />Pages 47-53, Flexion Mesolarvae, sequences of steps following option b (absent) in Step 3 (page
<br />47): update to include the rare possibility of 14-mm-SL C. latipinnis without yolk.*
<br />(Based in part on mesolarvae collected from the Yampa River in 1976-LFL# 69949.)
<br />Pages 47-53, Flexion Mesolarvae, sequences of steps following option a (~21 melanophores) in
<br />Step 7 (page 47) and options a and b (both ~21 melanophores) of Steps 22, 25, and 44
<br />(pages 48 and 50): update to include the rare possibility of C. ardens with greater than 20
<br />melanophores in a midventralline between heart and vent. *
<br />Pages 47-53, Flexion Mesolarvae, sequences of steps following option b (5:20 melanophores) in
<br />Step 7 (page 47) and option c (7-20 melanophores) in Steps 22 and 44 (pages 48 and 50):
<br />update to include the rare possibility of C. platyrhynchus with 7-20 melanophores in a
<br />midventralline between heart and vent. *
<br />Pages 48 and 50, Flexion Mesolarvae, Steps 16 and 48: update options a and b to begin "with>
<br />12 melanophores . . . ." and add option c "with 5: 12 melanophores . . . . X texanus."
<br />(Based on observation of 0-12 melanophores on the dorsum of 10.5-11.4 mm SL
<br />proto larvae and flexion meso larvae collected from the Green River at River kilometer
<br />302.9, Cliff Creek, Utah on 23-30 May 2001-LFL# 80501-80504,80506,80508-80509,
<br />80513, and 80515-80516.)
<br />Page 48, Flexion Mesolarvae, Step 22: update option 22c to "1-20 melanophores or without
<br />pigment (Figs. 16,58) . . . . . .27" and delete option 80e and back references to Step 22 in
<br />Step 47 on page 50 (allows for rare occurrence of C. latipinnis postflexion mesolarvae
<br />without ventral midline pigmentation).
<br />Page 53, Flexion Mesolarvae, Step 89: correct from "(lateral midline below" to "(lateral midline)
<br />" and below."
<br />Page 54, Flexion Mesolarvae, Step 109: addblank line before this step to separate from Step
<br />108.
<br />Page 54, Postflexion mesolarvae, Step 1, option f: update to "16 mm . . . . 2C" and insert new
<br />Step "2C (1). Yolk" with options "a. present.... C. latipinnis" and "b. absent.... 80"
<br />to provide for rare possibility of l6-mm-SL C. latipinnis still bearing some yolk. (Based
<br />in part on mesolarvae collected from the Yampa River in 1976-LFL# 69952.)
<br />Pages 55-72, Postflexion Mesolarvae, sequences of steps following options a and b (both ~ 21
<br />melanophores) of Steps 10, 27, 44, 80, and 101: update to include the rare possibility of
<br />C. ardens with greater than 20 melanophores in a midventralline between heart and
<br />vent. *
<br />Pages 55-72, Postflexion Mesolarvae, sequences of steps following options c (7-20
<br />melanophores) and d (1-6 melanophores) in Steps 10,27,44,80, and 101: update to
<br />include the rare possibility of C. platyrhynchus with 6-20 melanophores in a midventral
<br />line between heart and vent, including new options lOe and 27e for species from former
<br />10d and 27d with no midventral melanophores. *
<br />Pages 56-72, Postflexion Mesolarvae, sequences of steps following option b (present) of Steps
<br />24 and 26: update to include the possibility of 13-mm-SLX texanus having some dorsal
<br />fin rays. *
<br />Pages 56-72, Postflexion Mesolarvae, sequences of steps following options c (7-20
<br />melanophores) and d (1-6 melanophores or without pigment) of Step 27: update to
<br />include the possibility of 14-mm-SL C. latipinnis. *
<br />Page 57, Postflexion Mesolarvae, Steps 41 and 42: update by deleting option a, changing option
<br />b to a and option c to b, and beginning the new option a (old b) with "absent or . . . ," and
<br />deleting back reference to Step 41 in Step 282. (Based on observation of 14-mm-SL C.
