Paeamicippa, M.-Udicards. Eostrum less vertically deflexed. 

 Anterior legs in the male with the palm enlarged, shorter, smooth ; 

 fingers, when closed, meeting only at the ends. Type Farami- 

 cippa platipcs (Riippell) . 



The eyes are, I believe, retractile in both genera ; and the cha- 

 racters derived from the orbital and antennal region are subject to 

 variation. 



Family III. PERICERIDiE. {Maiens cryptophthalmes, M.-Edwards, 



part. ) 



Eyes retractile within the small circular and well-defined orbits, which 

 are never incomplete as in the Maiida?. Basal antennal joint well 

 developed, and constituting the greater portion of the inferior wall of 

 the orbit ; this joint is usually very considerably enlarged. 



Subfamily 1. PERiCERiNyE. (Sec Plate XIII. figs. 4, 5.) (Pericerina;, 



Stimpson.) 



Carapace more or less subtriangular in shape. Rostrum well deve- 

 loped. Second joint of antennae not dilated. Anterior legs with the 

 fingers acute at the tips. 



In this subfamily are included those which may be regarded as 

 the typical genera of this family, in which the spines of the ros- 

 trum are well developed, and often in contact with one another. 

 The interorbital space is very broad, and the orbits tubular ; the 

 basal joint of the antenna) very much enlarged, the epistoma 

 short, the legs of ftioderate length, and the fingers acute at 

 tips. One or two of the genera {Scyra, 8plienocarcinus), in which 

 the basal antennal joint is least developed, are related to the 

 Epialtinse. 



§ Nostrum emarginate at apex only. 



LiBiNiA, Leacli. Carapace orbiculate-triangular, convex, spi- 

 nose. Pra)ocular spine distinct. Basal joint of antennje mode- 

 rately enlarged. Legs of moderate length. Type Lihinia emar- 

 yinafa, Leach. 



Peionoehynchus, Jacquinot Sf Lucas. Carapace subtriangular. 

 Pra30cular spine absent. Kostrum broad, lamellate, deflexed and 

 emarginate at its distal end. Basal joint of antennae greatly en- 

 larged. Type Frionorhynchus £Jdwardsn, Jacq. & Lucas.
