NOTES ON MICHIGAN CRUSTACEA, II. 
A NEW MICHIGAN ASELLUS, 
BY A. S. PEARSE, HONORARY CURATOR OF CRUSTACEA, UNIVERSITY OF MICHIGAN 
MUSEUM. 
On March 10, 1911, Miss Mae Williamson collected three isopods, two 
males and a female, from a ditch at Steere’s Swamp, south of Ann Arbor 
(University of Michigan Museum number 42312). The specimens were 
given to the writer for identification and proved to belong to a species 
not previously recorded from this state, — Asellus intermedius Forbes. 
This species is readily distinguished from the other Michigan Asellus (A. 
communis Say) by possessing small lateral lobes on the head near the 
posterior angle, by the 7-segmented flagella on the first antennae, and by 
the longer second antennae which extend to the posterior margin of the 
seventh thoracic segment. Its occurrence in a swampy ditch in Michigan 
is of interest for it has previously been reported from only two localities: — 
“in hill country in southern Illinois, under stones in small streams,” and 
from “the Potomac River near Washington.” 1
