The Vibilia?, like the Hyperice, the Phronimce, and the OxycephaU, have always 

 been recognized and niaintained in their true characters, ft-om the foundation of the genus 

 in 1830 to these days. This probabh' depends only on the habitus of the animals 

 being so striking that it could not be mistaken even by naturalists little experienced 

 in carcinological matters. The Vibilite are the only Hyperids which have from the 

 iirst been pointed out as an independent group in opposition to the other Hyperids. 

 H. MtLNE Edwauds in 1840 (see above) ranged the genus Vibilia in the first tribe of 

 the Hyperids, viz. »Tribu des Hyperines gamniaroideso. Dana, following Milne Ed- 

 wards, 1852 placed the genus in his tamily Hy]jerida3, as the tirst subfamily Vibi- 

 linas, but he added no new species to the genus. It contained then only two species, Vi- 

 hilia Peroni,X]\c iyinc-äX one of Milne Edwards, and Vibilia Jeangernrdi, described in 1845 

 by Lucas') from the Mediterranean. C. Spence Bate in 1862^) increased the number of 

 species to four — Vibilia Edicardm and V. affinis being the new ones — but rejected the 

 subfamily Vibilina^ of Dana and ranged the genus Vibilia among the other members of 

 the family Hyperida? between Hyperia and Cylloi)us. In the year 1872 Claus (see above) 

 restituted the Vibilife as a division of its own, proposing the new family-name Vibilidaj, 

 Avhich has been since retained in the zoological hand-books. 



The family contains many species, but according to my apprehension these may all 

 be easily ranged within the old genus, so that there is no reason to establish any new 

 genera in the family. 



Genus 1. VIBILIA, H. MILNE EDWARDS, 1830. 



Diagn. Giput parvum, fere quadratum. Oculi ovati vel subovati. Pedes pereii primi paris simplices 

 non chelati, pedes secuudi paris plus minusve subcheliformes. Femora pedum septinii 

 paris articulis sequentibus coujunctis non longiora. Telson niaguum, lingulatum. 

 The head is small, almost quadrangular. The e>/es are ovate or subovate. The first pair of 

 pereiopoda are simple, not cheliform, the second pair are more or less subcheliform. The 

 femora of the seventh pair are not longer than the following joints together. The telson 

 is large, tongue-shaped.
