698 Mfi. H. G, JACKSON ON THE 



specimens weve all females. An examination of Chilton's 

 original specimens of novce-zecdandice showed that the antennse 

 were shorter iu the female than in the male, and that the females 

 agreed entirely with Budde-Lund's cursor. Fragments of a 

 specimen, labelled "Z. cursor (male)," from Chile, in Budde-Lund's 

 collection, proved to have subclielate 1st legs like those of the 

 male of the oiovce-zealandice. The cursor described by Budde- 

 Lund is therefore synonymous with Dana's novce-zealandice. 



Dana's original account oi L. cursor i\9)02) figures and describes 

 the telson as triangulate. Budde-Lund was misled by the locality 

 of his specimens into crediting Dana with an error on that point, 

 and hence gave a description of L. novce-zecdandice from S. America 

 (specimens of which he thought he had not seen) under the 

 name of L, ctorsor. The latter species has not apparently been 

 found since Dana described it from " Valparaiso." 



The matter is of considerable interest, as Chilton has already 

 had occasion to observe (1909 a & 1915) the similarity of fauna of 

 South America and New Zealand in connection with other 

 terrestrial and aquatic forms. 



Figured and described in detail by Chilton (1901).

Male specimen described. 



Length 20 mm. Breadth 9 mm. 



Surface rather coarsely granular. JiJi/es large and separated by 

 less than their horizontal length. Antennce long and slender ; 

 flagellum reaching as far back as hind border of last thoracic 

 somite, peduncle to hind border of 2nd. Antennse slightly 

 shorter in the female. Flagellum with 29 small and slender 

 segments. Goxcd plates very faintly marked on 2nd, 3rd, and 4th 

 thoracic somites. In the female they are very distinct on the 

 corresponding somites. Abdomen not abruptly contracted. 

 Telson triangulate; median process bluntly rounded; postero- 

 la.teral processes acute, but not projecting as far back as median 

 process ; accessory processes represented by undulations. Mouth- 

 parts : 2nd maxilla bilobed, but without hairy bristles on inner 

 side. Maxillipede palp with five distinctly separate segments. 

 Propodus and carpus of 1st peros,opod(m. male only) each produced 

 on inner side to a flat plate-like expansion ; free borders each 

 fringed with a comb of exceptionally long and markedly equal 

 setse. The plates are obliquely striated. TJropods (separate) 

 12"5 mm. The uropods on the female specimens wei^e shorter in 

 proportion than these, which possibly, however, did not belong to 

 the specimen described above. (In an 18 mm. female the uropods 

 measured 8*5 mm.)
