An examination of more than fifty specimens of a harvest-spider in 
various stages of development taken along the banks of the Maumee 
River in Henry County, leads to the conclusion that the form from 
Illinois described some years ago as Liobunum elegans is an immature 
stage of the male of L. bicolor. A reexamination of the type speci- 
men of Mitopus ohioensis after it has been in alcohol more than four 
years shows that it was apparently just ready to moult when captured. 
This gives rise to the suspicion that this is an immature form of M. 
pictus, the pink coloring possibly being due to the peculiar conditions 
of the moulting period. 
The study and measurement of a considerable number of specimens 
of Liobunum ventricosum from many States shows that this species 
increases in size to the southward in a way similar to that of L. vitta- 
tum. The southern form is evidently sufficiently distinct for a subspe- 
cific name, and as the form now standing as Forbesium hyemale is 
pretty certainly an immature stage of it, the subspecies may well take 
its name and be known as L. ventricosum hyemale. 
Illustrated papers on both these subjects are ready for the printer, 
and will appear in the near future. 
Professor C. H. Tyler Townsend, of the New Mexico Agricultural 
College, recently sent me specimens of an undescribed species of Lio- 
bunum taken at Las Cruces. It may be called L. townsendii. Its 
description is as follows: 
Male.—Body 5 mm. long, 3.7 mm. wide; palpi, 5 mm. long. Legs, 
first, 43 mm.; second, 80 mm.; third, 45 mm.; fourth, 59 mm. Gen- 
eral color of dorsum brown, approaching raw umber, with indistinct 
darker blotches, but no central marking. Ventrum light grayish 
brown. Palpi similar in color to ventrum, with dorsal surface of 
patella and of tip of femur darker brown. General color of legs raw 
umber, with whitish rings near articulations and blackish ones at 
articulations. Dorsum minutely tuberculate; articulation of the three 
posterior segments very distinct. Eye eminence rather high, nearly
