length of the legs in both sexes, the difference in the male 
palpi and the number and arrangement of spines on the 
legs do not agree with any of the genera from Central 
America, so the new genus Anyphsenella has been made 
for them. 
1. Ventral furrow one-third nearer epigastric plate than 
to spinnerets Aysha. 
Ventral furrow one-third nearer spinnerets than to 
epigastric plate, anterior median eyes largest 
Marcellina 
Ventral furrow about midway between epigastric plate 
and spinnerets, anterior eyes equal or median slightly 
smaller 2. 
2. Anterior tibiae as long as both cephalothorax and 
abdomen Anyphaenella 
Anterior tibiae normal Anyphaena. 
Marcellina gen. n. 
Type: Clubiona piscatoria Hentz. 
Cephalothorax oval, thoracic groove rather long, front 
broad and obtuse. Anterior row of eyes slightly recurved, 
equidistant, median largest of the eight ; posterior row pro- 
curved and equal; quadrangle higher than wide, wider in 
front; lateral eyes separated by less than diameter of an- 
terior laterals. Clypeus not as wide as diameter of anterior 
median eye. First leg longer than fourth; anterior legs 
with few spines on ventral side. Mandibles of male well- 
developed with two widely separated teeth on superior 
margin of groove and two teeth on inferior margin. Ven- 
tral furrow one-third nearer spinnerets than to epigastric 
plate. 
The genus differs from Gayenna, which has the ventral 
furrow near the spinnerets, by the large median eyes and 
from the other American genera by arrangement of the 
eyes, number of teeth on the mandibles and the shorter 
spines on the legs.
