geographical position between the Coast Range and both the Wallowa 

 Mountains and Montana. Furthermore, Canyon City is only about 110 

 mi (176 km) southwest of the type locality of B. bifurcata. Therefore, 

 I borrowed the types of both B. bifurcata and T. curvata 

 for direct comparisons with that of glomerata. Few setae remain on 

 the types of B. bifurcata, and those that do exist, on the caudal end 

 of the male holotype, seem shorter and are not nearly as prominent 

 as are those on glomerata. However, the setae on glomerata agree 

 closely in length and prominence with those on the holotype of T. 

 curvata. There is reasonable agreement in body dimensions between 

 glomerata and both other conotylids, but because of the similarity in 

 the setae, I provisionally assign glomerata to Taiyutyla, pending 

 collection of a male topotype. This change, which formalizes Shear's 

 (1971) perception of similarity to Taiyutyla, also necessitates the feminine 

 suffix of the specific name. Fieldwork is needed in the Blue Mountains 

 to collect a male conotylid to determine the identity and generic 

 position of glomerata and to confirm or disprove this decision. 



Present evidence shows that the Conotylidae is much more wide- 

 spread in the West than currently known. There is a female in the 

 Florida State Collection of Arthropods from 12.5 mi (20 km) south 

 of Baker City, Baker County, Oregon, that might be conspecific 

 with glomerata, although this site is east of the Blue Mountains and 

 presumably is drier than Canyon City. I also recently received two 

 female conotylids that are superficially very similar to glomerata from 

 the Snake Mountains, White Pine County, Nevada, in the eastern part 

 of that state and hundreds of kilometers from any known site for the 

 family. These two records plus glomerata suggest that conotylids could 

 be scattered across the arid Columbia Plateau and Basin and Range 

 Physiographic Provinces, where they are undoubtedly restricted to cool- 

 er, forested regions at high elevations. The Ruby Mountains near Elko, 

 Nevada, is another plausible area for conotylids, as are ranges in the 

 central part of that state. Because only a few millipeds of any family 

 have ever been collected from the "inselberg" mountains of these 

 provinces, a concerted field effort is needed to both clarify the systema- 

 tic positions of these conotylids and document the total diplopod fauna.
