The head is rostratc, longcr lliau tlic Krst two pereional segments. The eyes are large, cir- 

 cular. The flagellum of the first pair of antennai is lanceolate, acute, shorter than the head. 

 The pereiopoda are short, robust, not hirsute. The secoud pair with verv short carpal pro- 

 cess. The tibiie of the third and fourth pairs are broad but not tumid, the dactyli are 

 long. The fifth aud sixth pairs are a little longer than the third and fourth; the femora 

 are broad, truncatc-ovate; the dactyli are middle-sized. The second and third »rdi! segments 

 are coalesced. The posterior corners of the last segment are not produccd. The peduucles 

 of the first and second pairs of uropoda are shorter than the rami, that of the third pair 

 longer than the corresponding rami. The telson is small, semicircnlar, much shorter than 

 half the peduncle of the last pair of uroj)oda.

Syn. 1887. Vibilia macropis, C. BOVAIjLIUS. »Systunuitic-iil list of tlic Ainpliipoda Hyperiidcii». IMli. t. K.

This species is very intefesting becau.se through the high developiuent of its e}"es 

 it eonnects the Vibilit/ce with the fyllo ijodidte; in all otlier vespect.s it i.s a true Vibilia, 

 though perhaps also the rami of the fii"st two pairs of uropoda may bear some re.sem- 

 blance to those organs in the Ci/llopodiclce. 



The /icaij is almost as long as deep, the ro.strum is very short, shorter than a fifth 

 of the length of the head. 



The eyes occupy almost the \vholc of the sides of the head; they consist each of a 

 little more than 300 ocelli. 



The fir.'<t pair of nntcniue (Pl. \"I11, fig. 2) are pro\ided with a \-ery stout peduncle, 

 the basal joiiit is longer than the two foUowing together. The flagelluni tapers evenly 

 towards the apex, the first joint is not twice as long as the peduncle (10:7), with some 

 few, very short spines along the upper margin. The terminal joints, two in number, are 

 comparatively large, provided Avith a few minute liairs.
