The type specimens of all five milliped species-Trichopetalum lunatum,
T. glomeratum, T. iuloides, Iulus furcifer, and Polydesmus armatus-an
d one of the two centipedes, Lithobius pinetorum, authored by Oscar Ha
rger in his only paper on myriapods and previously thought to be lost,
are housed at the Peabody Museum of Natural History, Yale University,
New Haven, Connecticut. From our knowledge of the itinerary of the Ya
le paleontological expedition of 1871, we know the type locality of T.
glomeratum, L furcifer, P. armatus, and L. pinetorum, previously stat
ed as the ''John Day River Valley, Oregon'' is restricted to the vicin
ity of Canyon City, Grant County, on the western slope of the Blue Mou
ntains. The female holotype confirms that T. glomeratum is a represent
ative of the chordeumatoid family Conotylidae, and the name is assigne
d provisionally to Taiyutyla pending collection of a male topotype. Un
identifiable female conotylids are also reported from another area in
eastern Oregon and the Snake Mountains in eastern Nevada, which sugges
ts that the family is widespread in montane forests at high elevations
in the generally arid Columbia Plateau and Basin and Range Physiograp
hic Provinces. To facilitate future studies, I provide gonopod drawing
s of male syntypes for I. furcifer and P. armatus.
