hinge without any definite angle, thence receding in a bold curve 

 to join tlie ventral margin ; the latter almost straight, posteriorly 

 ascending somewhat and merging into an evenly rounded tip. 

 FetJiale of similar shape, but with back more vaulted. 



Head with rostral expansion in female short and generally 

 acute at the tip, but sometimes obtuse like E. dahli ; in the male, 

 compared with that species, very much longer, and not acutely, 

 but bluntly, pointed. 



Legs, 20 pairs. Male with two first pairs of legs subchelate, 

 subapical appendage long, three-jointed ; hands in lateral view 

 subquadrate, inner margin above the thumb-like projection with 

 an angular prominence. Fourth leg not having a rudimentary 

 joint to fifth endite as in E. dahli, remaining pairs as in the 

 female, except that in the latter the ninth and tenth pairs have 

 the proximal lobe of the exopodite with a long thread-like 

 appendage. Tail long, with the two longitudinal dorsal ridges 

 almost straight, each possessing very many (about 20) acute little 

 denticles, also from 3-5 pairs in front of the anal setae only 

 slightly larger than the others. Movable caudal claws evenly 

 curved upwards, and not more than the proximal half bearing 

 feathered setae ; in E. dahli they are much straighter, and the 

 greater part of their length bears feathered setae. 



Size. — ^?, length about 9 mm., width variable; $ , rather less 

 in length and proportionately narrower. 



Distribution. — Neighbourhood of Rivoli Bay, South Australia 

 (Brady) ; Upper Onkaringa Creek, Central Australia (S. and H.); 

 Cheltenham, Southern Victoria ; and, if my supposition of its 

 being synonymous with E. sordida. King, is correct, also New 

 South Wales. 



Remarks. — I have been enabled to examine specimens of this 

 species collected from the same neighbourhood as the types came 

 from, also a few specimens fi'om Victoria. The latter agree in 

 all respects with the former except that the shape of the shell 

 posteriorly is deeper and more broadly rounded. As in other 

 species of Eulimnadia males occur in much fewer numbers than 

 females. 



4. Eulimnadia victoriensis, sp. nov. (PI. XXXITL). 



Description. — Shell smooth, very thin and translucent, much 

 compressed, without any umbones ; lines of growth inconspicuous,
