stout and smooth. No translamella ; pseudostigmatic organ with medium length 

 stem and fusiform head. Interlamellar hairg long, stout, smooth. Femora with 

 blades. Abdomen hairless. Legs about the length of abdomen, moderately set 

 with long fine hairs. Unguis tridactyle. Last three pairs of legs inserted at edge 

 of body. Anterior corners of abdomen not projecting. Several specimens under 

 large stone, Claremont, Cal. In classifying this species in the genus Notaspis 

 I have followed Michael. Michael and Banks disagree about this genus, Michael 

 describing Notaspis as having the body smooth, while Banks affirms that the body 

 is more or less rough. As this feature is used in both keys it is apt to cause con- 

 fusion if the disagreement is not noticed. This species is most like N. burromsi 

 Michael, but differs in having no hairs on the abdomen, no translamella, and sim- 

 ple hairs on the legs.
