134 History of British Entomostraca. 



The figure given by Muller is much better than that of Jurine. 

 Shell somewhat of a rhomboidal form ; rounded at posterior, and 

 truncated as it were at anterior margin ; glabrous, with a few hairs 

 on posterior margin ; surface of shell as it were reticulated, or, as 

 Muller says, marked with small points impressed into, or as it were 

 excavated out of shell. Upper part of shell is nearly of a white co- 

 lour ; lower portion, anterior margin, and part of posterior one,|of 

 a black colour, shaded with a yellowish green ; filaments of anterior 

 feet long. A very pretty and well-marked species.

The figure given by Joblot, referred to above, appears to me to 

 be undoubtedly the Candida, though, curiously enough, Muller him- 

 self refers it to his pubera, while Straus again refers it to hisyw*- 

 ca. The figure given by Muller is not good, that of Jurine is much 

 better. The shell is smooth and shining, but fringed round the 

 margins with fine hairs of a pure white-colour, with a pearly lustre, 

 nearly opaque, ventricose : anterior extremity narrower and flatter 

 than posterior, which is arched ; upper margin raised, lower some- 

 what reniform ; filaments of anterior feet consist of only three or 

 four short hairs ; animal generally creeps near the bottom of the 

 vessel in which it is kept.
