466 Hentz's Descriptions of the 
Genus Cyrroropnia.. Mihi. 
Characters. Cheliceres small; maille short, inclined 
over the lip ; lip wider than long, triangular ; eyes six, sub- 
equal, two very small, placed near together in the middle, 
two larger far apart placed above, and two placed each on a 
tubercle on the side; feet, fourth pair longest, then the first, 
the third shortest. 
Habits. Araneides sedentary, making a cocoon. 
Remarks. This anomalous spider appears to be related to 
Eprira. I found it in the attitude of one, suspended from a 
thread or web which I would have examined carefully, had I 
not taken it as a new species of that sub-genus. It has cer- 
tainly six eyes only ; its cephalothorax is flattened in the mid- 
dle, being deeply excavated behind ; the last joint of its palpi 
are terminated with a small nail; its abdomen is gibbous and 
rugose, covering anteriorly a great part of the cephalothorax, 
with four mammule and a cauda ; the two anterior pair of 
legs are directed forward, and the other two in the opposite 
direction, so that the sternum has a vacant place in the middle. 
The trophi are nearly those of Errira, but approach TuE- 
RIDIUM. ‘The cheliceres are very small, but capable of recip- 
rocal motion.
