Comments on the type locality and previous descriptions. Banks 
(1896) wrote only “Black Mtn., Calif.” for the type locality. Other 
species described in the same paper were collected by the same col- 
lector (R. W. Doane) from the Palo Alto area. This implies that 
the type locality of A. californicus is Black Mountain in northwest- 
ern Santa Clara County. Smith (1908), who knew Doane well, 
states confidently that the type was collected on Monte Bello Ridge 
of this mountain. The following species description is based partly 
upon a male and a female collected on Montebello Road, presumably 
very close to the type locality. 
Banks’ (1896) description is based upon an immature specimen, 
is brief, and does not include characteristics which distinguish A. 
californicus from some other Aliatypus species. Smith’s (1908) de-
