just above the insertion of the caudal setæ, 2 somewhat 

 stronger, juxtaposed spines occur. The caudal claws are 

 well developed, and of a structure very similar to that in 

 the genus Eulimaclia. 



The eyes (see figs. 5 & 6) are wholly confluent, constitu- 

 ting a single organ placed immediately within the most promi- 

 nent part of the frontal face. It is of moderate size, and 

 when viewed in front (fig. 6), exhibits, in its upper part, a 

 small incision as a trace of the original duplicity of the 

 organ. 



The ocellus (ibid.) occurs at some distance below the eye, 

 and nearer to it than to the tip of the rostrum. It exhibits 

 the usual prismatic shape. 



The antennulæ (see fig, 5) are comparatively more fully 

 developed than in Eulimadia, attaining about half the length 

 of the head. They are thread-like and very flexible, being 

 divided into a number of distinctly-defined articulations, each 

 of which forms anteriorly a rounded expansion densely clothed 

 with olfactory papillæ. 



The antennæ (see fig. 3) are very fully developed, and of 

 a structure similar to that in Eulimadia. The rami are com- 

 posed of from 12 to 14 articulations. 



The oral parts (see fig. 5) are also constructed upon the 

 very same type as in that genus. 



The legs are 20 in number, being, as in Eulimadia, of a 

 rather uniform appearance, and membranous consistency. Though 

 constructed upon the same type as in that genus, they ex- 

 hibit, on a closer comparison, several Avell-marked diiferences 

 (see fig. 7). The stem is comparatively more expanded in its 

 proximal part and has the terminal part less sharply defined 

 from the former. The coxal lobe is strongly curved, almost 

 falciform, and tapers to an acute point. It is provided inside 

 with the usual transverse row of curved setæ, and is moreover 

 clothed on the outer edge Avith numerous delicate, jointed
