Catalogue of our species of OPHION, ANOMALON, PANISCUS and CAMPOPLEX. 



IJY EDWARD NORTON. 



The synopsis of geneva here adopted is that proposed by Dr. Ilolmgreu. 

 The genera rcniaiuing undescribed are more numerous and contain many 

 small species, which require a large collection of specimens to do them 

 justice. Several species which seem to approach the genus Ahsyrtus are 

 omitted for further examination. 



Where not otherwise mentioned, the terebra is not longer than the width 

 of the apical segment.
