XVI CLASSIFICATION 437 
As already stated, Simon does not consider the possession of 
the two—often very feebly developed—eyes of generic importance, 
and admits only the genus Chelifer. 
Five species of Chelifer (including Ch. cancroides) and five 
of Chernes have been recorded in England.

cyrneus, enlarged. museorum, enlarged.

Sub-Fam. 2. Garypinae——The Garypinae have the cephalo- 
thorax greatly contracted in front and often projecting con- 
siderably. 
There are three genera, Chiridium, Olpium, and Garypus. 
Chiridium is eyeless, and appears to have only ten segments in 
the abdomen, the tergal plates of which are 
bisected. C. museorwm is found in England, 
and is the only Chernetid except Chelifer 
cancroides which habitually lives in houses. 
C. ferum is found under bark in the south 
of France. 
Neither Olpium nor Garypus, which both 
possess four eyes and eleven abdominal seg- 
ments, have as yet been found in this country. 
Garypus, like Chiridium, has the dorsal ab- F's. 227. — Olpiwm

dominal plates bisected. There is a transverse (After Simon.) 
stria on the cephalothorax, and the eyes are 
far from the anterior border. In Olpiwm the dorsal plates are 
undivided and the eyes more anterior. 
Sub-Fam. 3. Obisiinae—The cephalothorax of the Obisiinae 
does not narrow—and is, indeed, sometimes broadest—anteriorly. 
The chelicerae are notably large, and the dorsal abdominal plates 
undivided. They are the most active of the Chernetidea, ordinarily
