names. My object this year was imperfectly attained by the 

 capture of five or six specimens of this species, but I was fortu- 

 nate in obtaining a much greater prize in an ostracod — Cypris 

 ornata, Miiller, new to the British fauna, and scarcely inferior 

 to any in size and beauty. The gathering was interesting in 

 another respect — several individuals of species usually white or 

 whitish in colour, were distinctly tinted with green, not as a mere 

 superficial stain, but in clouded patches evidently entering into 

 the substance of the shell : these were Candona Candida, Cypris 

 gihba, and Limnicythere inop)inata. The fact is useful as show- 

 ing that colour must not be accepted as at all a constant or in- 

 variable character, even in species v/hich seem to be most stedfast 

 in that respect. The following list embraces all the Ostracoda 

 found at Fulwell.

Carapace of the female, seen from the side, oblong, subreni- 

 form, higher in front than behind, greatest height situated a 

 little in front of the middle and equal to half the length : extre- 

 mities rounded, the posterior much narrowed, superior margin 

 much elevated (almost gibbous) about the anterior third, thence 

 sloping with a gentle curve backwards, inferior sinuated in the 

 middle ; seen from above oblong-ovate, widest in the middle, 

 thence tapering evenly to the extremities which are pointed, 

 greatest width considerably less than half the length. The shell
