380 ARKIV FÖR ZOOLOGI. BAND 1. 



St. of the 1st p. narrow, coarsely serrate, of the other pairs 

 knife-like, finely serrate. Se of Re 3 of the 2 — 4th p. divide 

 the joint in 3 almost equal parts. Se of Re 2 of the 2nd p. 

 larger than the other. Si of Re 1 of the 1st p. 1, 1, 4 of 

 the other pairs 1, 1, 5. — The two joints of Ri are in all 

 pairs of eqnal length. — Se 0,1 on the 1st p., 0,2 on the 

 2 — 4th p. — Si 3,5 on the 1st and 4th p., 3,6 on the 2nd 

 and 3d p. 



Fifth pair of legs slightly asymmetrical. Re 3 times 

 longer than Ri, with bifid apex and 2 small Se. Ri with 

 bifid denticulated end. 



Nearly akin to L. wollastoni, bnt differs chiefly in the 

 shape of the 5th p. of legs. The enormous dorsal apophysis 

 of the genital segment may perhaps be anomalous, which I 

 cannot decide as I had only one specimen. 



Additional. 



When the above was in the press I received a copy of 

 the publication: Thompson, I. C. & Scott, A. Report on the 

 Copepoda collected by Professor Herdman at Ceylon in 1902. 

 — Published 1903. (From the »Report to the G-overnment 

 of Ceylon on the Pearl Oyster Fisheries of the Grulf of 

 Manaar».) 



The following there described new species are identieal 

 with the above described, viz.: Centropages tenuiremis Thomps. 

 & Se. == C. arabicus Ciev. C. dorsispinatns Thomps. & Se. 

 = C. notoceras Clev. Labidoeera pectinata Thomps & Se. = 

 L. similis Clev. My names are thus to be exchanged for those 

 given by Thomps. & Se.
