says that fallax, "apart from the number of teeth [4] on the raptorial 

 dactylus and other characters, differs from S. fasciata in the complete 

 suppression of the mandibular palp." This palp is also absent from the 

 species here described. 



As in miles, the anterolateral angles of the carapace of S. swetti 

 are not spined and the rostrum is somewhat longer than broad; in 

 fasciata the rostrum is "scarcely broader than long" ; in fallax the rostrum 

 is quite long and attenuated distally, being about 1% times as long as 

 its greatest width.
