The Vibilise, like the Hyperice, the Phronimce, and the Oxycephaly have always 

 been recognized and maintained in their true characters, from the foundation of the genus 

 in 1830 to these days. This probably 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 Vibiliae are the only Hyperids which have from the 

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

 H. Milne Edwards in 1840 (see above) ranged the genus Vibilia in the first tribe of 

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

 wards, 1852 placed the genus in his family Hyperidse, as the first subfamily Vibi- 

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

 bilia Per oni, the typical one of Milne Edwards, and Vibilia Jeangerardi, described in 1845 

 by Lucas 1 ) from the Mediterranean. C. Spence Bate in 1862 2 ) increased the number of 

 species to four — Vibilia Edwardsi and V. afjinis being the new ones — but rejected the 

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

 the family Hyperids between Hyperia and Cyllopus. In the year 1872 Claus (see above) 

 restituted the Vibilia3 as a division of its own, proposing the new family-name Vibilidee, 

 which 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. 



Diagll. Caput parvum, fere quadratuin. Oeuli ovati vel subovati. Pedes pereii primi paris simplices 

 non chelati, pedes secundi paris plus minusve subcheliformes. Femora pedum septimi 

 paris articulis sequentibus conjunctis non longiora. Tels'on magnum, lingulatum. 

 The head is small, almost quadrangular. The eyes 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.
