Genus HEMISQUILLA Hansen, 1895^3 



The genus comprises at least 2 species, H. styltfera (M.-Edw.), 1837, 

 described from the coast of Chile, and H. braziliensis (Moreira), 1905, 

 from the coast of Brazil. The substitution of the name of bigelowi Rath- 

 bun, 1910, for stylifera M.-Edw. because of conflict with styltfera La- 

 marck, 1818 [= Pseudosquilla ciliata (Fabr.), 1787] within the genus 

 Pseudosquilla needs no longer to be taken into account, since the first- 

 named stylifera is now the type of Hemisquilla. 



Although the Hemisquillas from Australia, Cah'fornia, and the west 

 coast of South America are so ver}^ much alike in practically all particu- 

 lars, as Kemp says, "it is not improbable that distinct races of [//•] sty- 

 lifera exist on the coasts of Australia and America, but this cannot be 

 established with any certainty without the examination of large numbers 

 of specimens from the two localities." 



I am inclined to believe that the difference in the number of lobes in 

 the interval between the submedian and intermediate teeth is of more 

 significance than may seem justified at present. Despite the fact that the 

 number of lobes in this position was not mentioned by Whitelegge^* in 

 commenting upon the 3 specimens he had from 28-40 fathoms from New- 

 castle Bight, New South Wales, it is known that the specimens from the 

 west coast of America do differ from certain Australian ones in the man- 

 ner figured by Kemp for one of his two specimens of stylifera from Dis- 

 aster Bay, Victoria. 



Kemp's Australian specimens have 2 rounded lobes between the sub- 

 median and intermediate spines of the telson, while his specimen from 

 Coquimbo, together with Miers'^^ from the same place, and his addi- 

 tional one from Chile without more specific designation, like Milne-Ed- 

 wards'^^ figured one, have but one lobe between the submedian and inter- 

 mediate spines. This is also true of the specimen Bigelow had from San 

 Pedro, and one in the National Collections from "southern California." 



H. braziliensis (Moreira)^''' from the east coast has also but a single
