THE CRUSTACEA OF XEW JERSEY. 



/o 



Also shorter and more slender claw in addition to terminal claw. 

 Color of shell yellowish-green, and marked with three broad 

 characteristic dark, or dusky, to dark greenish transverse bands 

 extending over dorsal surface. Shell also covered with short 

 sparse hairs. Length 0.54 to 0.70 mm. 



Remarks. — Found at South Dennis, near Florence and at Tren- 

 ton, during the past year. It does not appear to have ever been 

 recorded from New Jersey before, though likely is to be found 

 everywhere during proper seasons. 



Several times in the spring I have found thousands above 

 Bristol, in Pennsylvania, in temporary pools, and as some of them 

 were stained somewhat dark, owing to the infusion of old leaves, 

 suspect that p>ossibly De Kay's Cypris hispida may have been 

 colored from a similar cause? This species was also found in 

 examination of the stomach contents of young sturgeons (Aci- 

 penser hrevirostrum) secured in the fall of 191 1 at Torresdale. 

 Pennsylvania. 



Sharpe says of it : "This species is ubiquitous, and I have yet 

 to know of a pond or stream in which it has not made its home. 

 It is seemingly always present in aquaria, and appears to play 

 the role of scavenger, thriving in situations to which other 

 Ostracoda seem to be totally unadapted. \'iewed with a low 

 power these creatures present a very pretty appearance as the}- 

 rapidly swim about, the banded shell at once attracting attention." 



I have allowed De Kay's Cypris hispida to fall provisionally 

 with this species, as it was likely a discolored specimen. De Kay's 

 description is as follows : 'A'alves when viewed together, re- 

 semble a minute ^lodiola. Epidermis uniform jet-black, and 

 covered with numerous whitish rigid hairs. Length, .09 to .1 

 mm." De Kay appears to never have examined living examples. 

 Possibly the jet-black coloration may be due to preservation, or 

 the condition of the water in which it was found. Xo writer 

 since De Kay's time appears to have met with it. In any case 

 De Kay's specific name cannot be used as it is preoccupied for 

 a species of Candona.
