314 Mr. P. H. Gosse on a supposed new Genus 



Bellidia Huntii, Gosse. 



As this is the only species known, no diagnosis can be 

 given ; but it may be thus described : — 



Beak simple, small, rounded, smooth, acute. 



Internal antennee of two filaments, the one projecting, the 

 other erect and strongly ciliated on one side (e) ; seated very 

 little above the external pair. 



External antennae one third as long as the body. Basal 

 plates very large ; in form one-fourth of a long ellipse ; a 

 single tooth in the outer edge, near the tip {h). 



First pair of feet small and short, both didactyle, consi- 

 milar ; the thumb gibbous, solid ; the movable finger some- 

 what shorter, slender, finely pointed, much curved, colourless, 

 and translucent {d). 



Second feet moderately long, very slender, didactyle ; hand 

 minute ; both arm and wrist many -jointed. 



Outer foot-jaws long, strong, foot-shaped ; the terminal joint 

 armed with strong teeth on the upper edge. 



Eyes not covered by any vault of the carapace, but project- 

 ing above the rostrum. 



Abdomen abruptly bent, much as in Ilippolyte ; attenuated 

 rapidly (a). 



Legs moderately long ; all monodactyle. 



Tail-plates large ; the outermost showing no trace of trans- 

 verse division (c). 



Length three quarters of an inch from end of rostrum to 

 end of tail. 



The specimen was a female, heavily laden with advanced 

 spawn : the ova large, globular, densely attached to the fringes 

 of the false feet, and thus increasing the apparent depth of the 

 animal'. 



Colour : a dark rich lake-crimson, marked, on the cephalo- 

 thorax and abdomen, with well-defined vertical stripes of 

 brilliant opaque white, imparting a zebra-like aspect to the 

 creature. The head bears two longitudinal stripes of white on 

 each side. The entire length of the back is dark red, with a 

 broad white stripe running down the median line. All the 

 limbs red. The ova of a dark sea-green hue. 



With considerable afiinity to the family Crangonidce on the 

 one hand, and to the Palgemonidge on the other, this little 

 creature is separated from the former by the chela3, from the 

 latter by the rostrum. It must be placed in the Alpheadte. 



With A Ipheus it agrees in the minute rostrum and in the
