Colour. 



Vibilia a/finis, Spence Bate. 

 Facsimile from Sp. Bate. Catal. Amph. Crust. Brit. Museum, pi. 49, fig. 8. 



Caput leviter rostratum, segmentis duobus primis pereii multo longius. Flagellum antennarum 

 primi paris elongatum, lanceolatum, capite cum segmentis duobus primis pereii multo lon- 

 gius. Pedes pereii curti, non hirsuti. Tibia? pedum tertii ac quarti parium non tumidae. 

 Pedes quinti ac sexti parium pedibus tertii et quarti paullo longiores, femora lata, ovata. 

 Pedes uri ultimi paris precedentes non superant. Telson parvum. 



The head is feebly rostrate, much longer than the first two pereional segments. The flagel- 

 lum of the first pair of antenna' is elongate-ovate, much longer than the head and the 

 first two pereional segments together. The pereiopoda are short, not hirsute. The tibiae 

 of the third and fourth pairs are not tumid. The fifth and sixth pairs are only a little 

 longer than the third and fourth; the femora are broad, ovate. The last pair of uropoda 

 do not reach beyond the preceding pairs. The telson is small. 



Length. 7 mm.

I have not seen any specimen of this species, but it seems to be well characterised by 

 its long superior antenna 3 , which are much longer than in any other known species. 



The head is as long as deep. 



The eyes are small. 



The first pair of antenna' have the peduncle half as long as the head, three-jointed; 

 the first joint is as long as the two following together, the flagellum is three times longer 

 than the peduncle, with the apex acute. 



The second pair of antenna? are slender, not longer than the first pair. 



The first pereional segment is as long as the second, the fourth is the longest. 



The first two pairs of pereiopoda are short, slender. The lower hinder corner of 

 the carpus of the second pair is produced anteriorly. 



The second and third ural segments are coalesced (?). 



The telson is squamiform.
