of T. iuloides. Harger was studious and an active reader, and Marsh 

 valued his scientific opinions in paleontology. However, Marsh would 

 not allow Harger to publish on vertebrate fossils, either alone or 

 jointly with him, so Harger 's only papers are on invertebrates — that 

 of 1872 on myriapods, two on isopods, and one on a fossil spider. 



From 1870 to 1873, Marsh led four vertebrate paleontological 

 expeditions of Yale students and recent graduates into the West 

 (Schuchert and LeVene 1940). The idea of such efforts arose from 

 preliminary explorations he made on a trip to the end of the trans- 

 continental railroad in Wyoming in August 1868 after attending a 

 scientific meeting in Chicago. The 1871 expedition traveled to regions 

 of Kansas, Wyoming, and Utah, where Harger collected 10 fossil 

 species. The group then rested a few days in Salt Lake City with 

 Brigham Young while Marsh prepared to explore a new area, the 

 John Day River Basin in central Oregon. After traveling 12 days by 

 rail and stage, the party crossed the Blue Mountains and arrived at 

 Canyon City, Oregon, on the John Day River on 17 October 1871, 

 where it waited several days for a military escort from Fort Harney, 

 75 mi (120 km) to the south. The group collected fossils from 31 

 October to 8 November in the John Day region before traveling down 

 the Columbia River to Portland; it then traveled to San Francisco and 

 returned east directly by rail or by boat via Panama. 



While the expedition was in the John Day River area, Harger, 

 or Harger and Professor G. H. Collier, collected four Oregon myriapods 

 that he described in 1872 — L. pinetorum, T. glomeratum, I. furcifer, 

 and P. armatus. Both the publication and labels in the vials give the 

 locality as just the "John Day River Valley," but knowledge of the 

 group's activities enabled me to infer a more precise site. The John 

 Day River arises on the western slope of the Blue Mountains in 

 Grant and Umatilla counties, flows westward into Wheeler County, 

 then heads northward to the Columbia River forming the boundaries 

 between Wheeler/Wasco and Sherman/Gilliam counties. It is not to be 

 confused with Days Creek, Douglas County, in the Umpqua River 

 drainage of southwestern Oregon, the probable type locality for Zantona 

 douglasia Chamberlin and Bollmanella oregona Chamberlin (Shear 1974, 

 Gardner and Shelley 1989), which Chamberlin (1941a) misnamed as 

 "John Day Creek." Because most millipeds require moist leaf litter 

 and much of the John Day Basin is in the arid rain shadow of the 

 Cascade Mountains, I (Shelley 1990) speculated that the site was probably 

 near the confluence of the John Day and Columbia rivers in either 

 Sherman or Gilliam county. However, as all the myriapods were collected 

 in October 1871, and the expedition reached Canyon City on 17 

 October and only collected fossils from 31 October to 8 November
