A number of species occurring in Japan, China, the Phihppines, etc., seem 

 to have been confused under the name L. asperaius Koch. It is difficult to 

 beUeve that the species described by Attems from the Hawaiian Islands 

 {Loc. cit.) is the same as that described by him from Japan in 1909 (Arkiv zool., 

 5, no. 3, p. 22). Of the first Attems states that the posterior angles of the 

 seventh, ninth, eleventh, and thirteenth dorsal plates are produced, of the 

 second that the sixth, seventh, ninth, eleventh, and thirteenth are produced, 

 though some variabiUty in the angulation of the sixth plate may be responsible 

 for this. He gives the coxae of the last two pairs of legs in the Hawaiian form 

 as unarmed ventraUy, while they are armed in the Japanese form, the respective 

 formulae for the anal legs being „"". ' ' ', and ,' ' V ^> and for the penult

Q ^ 2 \ ~Q a^^ \ \ z *>' r Assuming Attems's observations to be accurate, it 

 appears impossible that these two forms should be the same species. Further- 

 more, both differ from the original description by Koch and from that given 

 by Haase (Abhandl. Mus. Dresden, 1887, 5, p. 33) of Phihppine specimens. 

 Haase gives the ventral spines of the anal legs as 1, 1, 3, 2, 0, as does also Koch 

 excepting that the latter fails to mention the spining of the first two joints. 

 For the Hawaiian form I am here accordingly proposing a new name, to be 

 used at least pending further elucidation of the Ethopolidae of Japan and the 

 Pacific islands. 



It seems also highly probable that the Japanese species described by Attems 

 in 1903 is not the true asperaius of Koch and Haase, not only because of the 

 marked difference in the spining of the legs as above indicated but also be- 

 cause of the fewer ocelli in the former, thirteen in three series as against 

 nineteen to twenty-three in asperaius. The Japanese species described by 

 Attems may accordingly bear the name Bolhropolys spinosior, nom. nov.
