Phyllopoda of Australia. 253 



than half the length of the shell, terminating posteriorly in a 

 distinct obtuse angle, thence declining obliquely hindwards, and 

 later merging into ventral margin in a narrow curve. Front deep, 

 leaving dorsal line without any angle, thence forming a regular 

 broad curve, set vertically. Ventral margin evenly convex. 

 Lines of growth, about ten ridges, each fringed with short, thick 

 bristles ; sculpture reticulate near the margin, becoming irregu- 

 larly hexagonal more distally. 



The animal is crowded within the shell, and quite normal to 

 the genus. It is characterised by a very prominent rounded 

 area in front of the confluent eyes, and the upper posterior limit 

 of the head segment projects backwards a little, but not nearly 

 so marked as in E. packardi. 



The branchial feet, compared with E. packardi, are consider- 

 ably broader, and the stylet produced from the fifth endite 

 (calling the coxal lobe the first) is only one — not two — jointed. 

 The hands of the two first pairs of legs are subquadrate, being 

 wider proximally than E. packardi ; the margin of the outer 

 side is almost straight, the inner straight for half its distance, 

 when it is abruptly cut inwards, forming a right-angled projec- 

 tion. This marks the origin of the thumb, which is half the 

 length of the hand, and is directed directly downwards, not 

 deflected outwards as in E. packardi ; also in that species the 

 inner margin gradually widens from the proximal to the distal 

 end, unbroken by any angular projection. 



The last few segments of tlie trunk have no spines, or only 

 minute ones, but more anteriorly they have a transverse series of 

 slender ones gradually increasing in size and number (about 10)^ 

 but these are not set on such prominent elevated projections, nor 

 are they quite so numerous, as in E. packardi. 



The tail segment is short and deeply concave al)ove ; in front of 

 the anal setae there is a single pair of short, straight denticles, broad 

 at the base and acutely pointed. The paired ridges bear but a 

 few very small irregularly set denticles, and terminate in a stout 

 upturned and curved one of normal size, that of each plate being, 

 as is usual in the genus, deflected at different angles. The 

 movable claws are comparatively short, and the inner margins, 

 clothed with feathered setae for about half their length.
