Psyche 
[December 
shalli is the only species not in the Museum of Comparative 
Zoology collection, and that is known only by the type. 
I am greatly indebted to Mr. Banks for his unfailing 
kindness and help, and to Mr. J. H. Emerton for the gen- 
erous use of his collection. Dr. W. M. Barrows has very 
kindly allowed me to examine the type of 0. mar shalli, 
and has generously given to the Museum of Comparative 
Zoology 0. neglecta collected by him at Hayden Falls, 
Columbus, Ohio. 
Ozyptila 
Cephalothorax slightly elevated. Anterior and posterior 
rows of eyes procurved, posterior row longer, laterals 
larger than medians and on separate tubercles, the anterior 
being the larger. Quadrangle higher than wide, usually 
with parallel sides, but occasionally wider in front. Abdo- 
men depressed, broad at base and rounded behind. Legs 
short and stout, I and II longest, tibia with 2-2 spines, 
metatarsus, 2-2-2 spines beneath and one or more lateral. 
Cephalothorox and abdomen roughened, and with the legs 
usually covered with clavate bristles and spatulate hairs. 
Male palpus rather short, tibia but little longer than 
patella, with two or three apophyses. Palpal organ simple. 
But little difference in size and markings between the sexes.
