70 Rhinichthys osculus. The speckled dace of the Interbasin contain several subspecies and a wide range of distribution. A recent paper by Jack Williams has given subspecific status to the Moapa form, R. o. moapae. The subspecies is now rare and has not been collected in large numbers. Reasons for the decline include exotic fish introductions and declining water quality. The White River speckled dace (R. o. velifer) is still common in the upper White River drainage, but adequate surveys are still lacking. The Pahranagat form of the speckled dace will be included in the G. r. jordani surveys. Other isolated populations will hopefully receive attention as time permits. Relictus solitarius. The steptoe dace is currently being threatened by oil well exploration and habitat modifications in Steptoe Valley. Lack of surveys, though, do not permit an overall evaluation of their status at this time. The transplanted population at Shoshone Ponds near Ely was visited in October, but no fish were observed. Lack of permits at that time did not allow seining to determine their presence. The permits have subsequently been issued, and population estimates will be conducted at the earliest opportunity. Pantosteus intermedius. The White River sucker is currently known to inhabit Preston #3 and Lund Town Springs. The presence of Poecilia and gold fish apparently is not affecting these populations, but other exotic introductions and habitat modifications could prove deleterious. Lepidomeda albivallis. The White River spinedace is also known to occur in Preston #3 and Lund Town Springs. They are numerous in these habitats, but lack of more adequate surveys do not permit a statement concerning their status throughout their range. Lepidomeda mollispinis pratensis. The Big Spring spinedace that had been previously reported extinct, then rediscovered in Condor Canyon by NDFG, may actually be,extinct. Following their rediscovery, flooding through the canyon has destroyed most of the new habitat. No adult fish were observed, and only small fingerlings of unknown species were found. This information was generously provided by Cal Allan. If further efforts produce adult fish, it would be advantageous to try a reintroduction into the type locality of Panaca Big Springs after exotic fish extirpation.
