On the Entomostraca of Berwickshire. :}()? 



from the second articulation of the tail arise the sexual organs in 

 either sex. This species approaches the C. chelifer of Muller, but 

 differs in many points when closely examined. In Muller's species 

 there are no articulations to the body, which gradually tapers to the 

 tail, and which he describes as " Jarciminis facie." The superior 

 antennae are only of three articulations ; the inferior, which he calls 

 " palpi," of two. The organs beneath these, which I call " palpi " 

 are furnished with a claw, and only of one articulation, whilst the 

 last pair of particular members, have only the shorter of the two 

 bodies of which they are composed, serrated, the longer being entire. 

 The male in Muller's figure has not the bullae on antennae. 



2. Cy there reniformis. Nova species. Sea-shore at Berwick and 

 Eyemouth, &c. Shell reniform ; flesh-coloured ; covered with hairs ; 

 both extremities of equal size ; antennae furnished with numerous 

 short setae to all articulations ; anterior feet falcate, entire ; all the 

 feet furnished with claws. This species approaches the C. viridix 

 of Muller, but differs in colour, in both extremities of shell being 

 equal, and in anterior feet not being serrulated. It differs from 

 C. lutea in shell being covered with hairs. 



3. C. alba. Nova species. Shore near Dunbar. Shell white, 

 transparent, hairy, acute at posterior extremity, and broader at 

 anterior ; a rim round edge of shell whiter than the rest of shell ; 

 antennas beset with short setae at each articulation. 



4. C. variabilis. Nova species. Shore at Cockburnspath and 

 Eyemouth. Shell glaucous, without hairs, ovate, anterior narrower 

 than the posterior extremity ; anterior legs falcate, and furnished 

 with pretty strong claws; antennas slender, without sets. This 

 species varies much in colour and markings. Some specimens are 

 white, with two black fasciae, one at posterior margin, and the other 

 across centre of shell, while the posterior extremity is marked 

 besides by a beautiful reddish or bright bronze spot ; other specimens 

 are of a light flesh colour, with the edges of shell slightly greenish, 

 and the body of the shell marked with dark streaks running across. 

 Some are altogether of a fine flesh colour ; while others again are of 

 a very dark brown. All the varieties, however, agree in shape of 

 shell, in size, &c, merely differing in colour and marking. Future 

 observations may perhaps determine them to be of two different 

 species. 



5. Cypris Joanna. Nova species. Pool near Abbey St. Bathans. 

 Shell roundish, ovate, narrower anteriorly than posteriorly; of a 

 brown colour, with an orange mark across back of shell and lower 

 margin ; shell beset all round with rigid hairs, and covered with 

 minute black points or dots ; setae of antennae numerous, about twelve 

 or more. Resembles C. vidua a good deal in shape, but differs 

 totally in colour and markings. Differs from C. pilosa somewhat 

 in shape, and in not being glabrous, but marked all over with black 

 roughish-looking points. 



(5. C. minuta. Nova species. Pool on Beaumout water at Yet- 

 holm. Shell broader posteriorly than anteriorly; elevated and 

 rounded on upper margin ; slightly sinuated on under margin ; hairv 

 all round; of a light brown colour with a tinge of green ; body of
