 1886, p. 12. P. grisea (Kraatz), by Fenyes, 1918, p. 24, not originally in- 

 cluded. P. maritima (Casey), by Fenyes, 1918, p. 24, for Pollstoma Casey,

 Discussion : I have been unable to see a copy of Stephens's second edition 

 of the Nomenclature. I must therefore rely on Tottenham's statement that 

 the genus is monobasic. However, in view of the fact that Stephens in 

 1835 did not mention olscureUa at all, and that Tottenham uses the word 

 monobasic in cases of supposed synonymy of the several included species, 

 there is still considerable room for doubt. If ohscurella is the only 

 species named in the original, it is the type by monotypy. Otherwise, the 

 type would be selected from among the included species by a later writer.
