and fleshy and armed along the inner edge with a long row of many 

 teeth, the terminal heing cylindrical in shape and pointed at the ex- 

 tremity. The superior antennae are four-jointed, and the front of 

 the head is of a quadi'angular shape. The ovarian sac in the fe- 

 male is long and rather slender, and appears to be notched at the

The body in this genus consists of the same number of segments 

 as in tlie three preceding, is soft and without covering, but is more 

 slender in shape, and has the caudal segment simply bilobed at the 

 extremity, instead of being armed with two large plumose fins. The 

 inferior antennae in the male are large, flat-shaped, broad, and di- 

 vided into two articulations. The basal joint has neither the antenni- 

 form appendage of Branchipus and Streptocephalus, nor the compli- 

 cated digitiform and fan-shaped apparatus of Chirocephalus. They 

 inhabit salt water, frequently even in water which is very highly 

 charged with salt. They swim upon their backs. 



The genus Eulimene was founded by Latreille in 18!7, in Cuv. 

 Regn. An. 1st edit. iii. 68 ; that of Artemia by Leach in 1819, in 

 the Diet. Sc. Nat. xiv. The term Eulimene, however, had been pre- 

 viously used by Peron for a genus of Acalepha, and though the name 

 Artemia is liable to objections from its construction (Artemia for 

 Artemis), I prefer adopting it to burdening the nomenclature with 

 another sjmonym. ' ' .^^niiii. ju. iv

This species, which seems to have been first observed by M. 

 Schlosser, in the salt-pans at Lymington, is nearly white, slender, 

 and about half an inch in length. The abdomen is long, fully as 

 long as the body, and the caudal segment is simply divided into two 

 small lobes, which give origin to several short setae. The inferior
