LFL# 81460-81495 (36 specimens, 8.9-47.2 nun TL) - From developmental series that was
laboratory-reared in 200lby LFL from Upper Big Creek Lake stock, Jackson County, CO
(brood 1); formalin.
LFL# 81496-81526 (57 specimens, 15.0-77.3 nun TL) - From developmental series that was
laboratory-reared in 2001by LFL from Upper Big Creek Lake stock, Jackson County,
CO; originally in formalin or ethanol, cleared and stained with alizarin red for skeletal
study, and since preserved in 100% glycerol.

Of the above, specimens specifically used for drawings were cataloged as:
LFL# 67223 (8.5 nun TL) - recently hatched proto larva, primary drawing specimen.
LFL# 67222 (7.6 nun TL) - recently hatched protolarva, secondary drawing specimen.
LFL# 67229 (10.6 nun TL) -later proto larva, primary drawing specimen.
LFL# 67228,67230 (10.2-11.1 nun TL) -later protolarva, secondary drawing specimens.
LFL# 67235 (12.5 nun TL) - recently transformed flexion mesolarva, primary drawing
specmen.
LFL# 67236-67237 (12.5-12.7 nun TL) - recently transformed flexion mesolarva, secondary
drawing specimens.
LFL# 67245 (15.1 nun TL) - recently transformed postflexion mesolarva, primary drawing
specimen.
LFL# 67243-67244 (14.8-14.9 nun TL) - recently transformed postflexion mesolarva,
secondary drawing specimens.
LFL# 67253 (17.5 nun TL) - recently transformed metalarva, primary drawing specimen.
LFL# 67254-67257(17.5-18.5 nun TL) - recently transformed metalarva, secondary drawing
specimens.
LFL# 81460 (22.5nun TL) -later metalarva, primary drawing specimen.
LFL# 81461-81462 (21.2-21.7 nun TL) -later metalarva, secondary drawing specimens.
LFL# 67263 (27.8 nun TL) - recently transformed juvenile, primary drawing specimen.
LFL# 67261-67262, 67264-67265 (26.7-27.8 nun TL) - recently transformed juvenile,
secondary drawing specimens.
LFL# 6990 (37.0 nun TL) -later juvenile, primary drawing specimen.
LFL# 6837,67265 (38.0-38.5 nun TL) -later juvenile, secondary drawing specimens.

Additional specimens in the reared series, including eggs, were cursorily examined or
measured and returned to the lot of specimens with which they were preserved. The source
developmental series for these specimens were cataloged as:
LFL# 67168-67219 (104 embryos, 2.3-3.0 nun dia.; 917 larvae-juveniles, 7.5-19.4 nun TL)-
reared in 1979; formalin.
LFL# 81190-81279 (154 embryos, 2.4-2.6 nun dia.; 5081arvae-juveniles, 7.0-53 mm TL)-
reared in 2001, brood 1; formalin.
LFL# 81336-81406 (8 embryos, 2.2-2.6 nun dia.; 417 larvae-juveniles, 7.4-43 nun TL)-
reared in 2001, brood 1; ethanol.
LFL# 81280-81335 (36 embryos, 2.4-2.8 nun dia.; 165 larvae-juveniles, 7.5-25.5 nun TL)-
reared in 2001, brood 2; formalin.
LFL# 81407-81459 (19 embryos, 2.2-2.6 nun dia.; 163 larvae-juveniles, 5.0 (abnormal) -29
nun TL) - reared in 2001, brood 2; ethanol.
