type of Alpha Smith, even if it later results that Smith did not know 

 that species, what he thought to be that, being in reality a very 

 different species. 



97. In regard to the genotypes of polybasic genera the following 

 rules apply: 



a. When an author, in describing a new genus, mentions or refers 

 to any valid specific name, except one doubtfully included or quoted 

 in synonymy, as type, typus, genotype, &c, or states that the genus 

 is "based on" or "erected for" (or such similar phrase) some one 

 species, then the species properly represented by that specific name 

 is the genotype, irrespective of misidentification. 



b. If a specific name not originally included in the genus, but 

 with an originally included species quoted in synonymy, is desig- 

 nated as the genotype of an established genus such designation is 

 deemed valid for the species in synonymy. 



Example. — Alpha Smith 1870, based on two new species, alba and 

 nigra. In 1880 the genotype is designated as "brnnnea Jones 1860 

 (== nigra Smith 1870)." Then, by the above rule, nigra Smith 

 1870 is the properly designated type of Alpha. 



c. If a genus, established in the text, is also given on a previous 

 page in a synoptic table with the mention of a valid specific name 

 or names, the type is not thereby selected or restricted. 



98. If the author of a polybasic genus has not established the 

 genotype by any of the above methods, it may be selected by any 

 one as follows: 



a. The first author to select as type one of the originally unques- 

 tionably included, specific names fixes the genotype, provided such 

 specific name has -not already been properly chosen as the type of 

 another genus, and such selected specific name represents the type, 

 irrespective of misidentification. 



b. If all the originally unquestionably included species of a genus 

 are already properly selected as types of other genera, any one of 

 them may be chosen as the type of this genus. 



99. A specific name cited as the genotype with a query, or indi- 

 cated as the probable type, is not thereby the type. 



100. If two or more species are cited at one place as types of one 

 genus, neither is thereby the type, nor is type selection restricted.
