Even while my recent (1970) revision of the milliped Family 
Conotylidae was in press, new data on the family had begun to 
accumulate. This paper is the first of a series of supplemental reports 
designed to update our knowledge of the conotylids, a group of milli- 
peds of considerable importance in biogeography. 
Like many other milliped genera and species, the genus Bvllman- 
ella , and its single species B. oregona, have remained enigmatic since 
they were described from a single male specimen by R. V. Chamber- 
lin in 1941. The description of the genus alluded mostly to body 
form and color, and even contradicted the specific diagnosis of the 
only included species. The description of B. oregona also contained 
errors, and no illustrations were provided. As if this were not 
enough, the type locality suggested an error of several hundred miles. 
The type of B. oregona was in the Chamberlin collection in Salt 
Lake City. The diplopod portion of the collection has remained 
uncurated since Chamberlin’s death and is in a confused state, but 
while my conotylid revision was in press, Mr. Thomas Lorenz, then 
in charge of the collection, found the holotype of B. oregona and 
loaned it to me. 
In 1973, I was fortunate in receiving a large number of Berlese 
extraction samples from Mrs. Ellen Benedict, Portland State Uni- 
versity, Portland, Oregon, and from Dr. David Malcolm, Pacific 
University, Forest Grove, Oregon. These samples were rich in 
millipeds of many groups previously known only from a very few 
specimens, and included literally hundreds of individuals of the 
related genera Taiyutyla and Bollmanella. Members of these genera 
must be among the more common humus animals in the area of 
coastal Oregon. As I mentioned earlier in reporting on part of these 
collections (Shear, 1973), northern California and the state of Wash- 
ington are much in need of the kind of thorough exploration by 
^art of the work for this paper was done while a Richmond Fellow at 
Harvard University.
