BRITISH ENTOMOSTRACA. 
Hitherto it had been described either as the Cancer 
salinus or the Gammarus salinus, according as authors 
chose to adopt the name given to it by Linnaeus or 
Fabricius. Latreille, however, in the first edition of 
‘ Cuv. Regne Anim./ 1817, describes it as a species of 
Branchipus, referring it correctly to the Phyllopoda ; and 
Leach, in the c Diet. Sc. Nat./ 1819, following up the 
arrangement, founded the genus Artemia to receive it, 
in which it has remained ever since. 
More recently the Artemia salina has been studied with 
care by Mr. Thompson, who, in the fifth number of his 
‘Zoological Researches/ 1884, informs us he received 
some specimens of it from Lymington, and though the 
adults all died, he succeeded in hatching the ova con- 
tained in the brine, and bringing the young to maturity. 
He readily distinguished the male from the female, and 
has given a number of figures, illustrating the anatomy of 
the adult animal, and the various changes which the young 
undergo in their progress to maturity. 
More lately still, M. Joly, of Montpellier, having found 
the species abundant in the salt-marshes in that neigh- 
bourhood, and more especially in the salt-pits or reservoirs, 
has devoted much attention to its study, and published a 
lengthened description of its anatomy and habits in the 
‘ Ann. Sc. Nat./ 1840. It seems curious, however, that 
he does not appear ever to have seen the males, and even 
asserts that Schlosser must have mistaken the young in- 
sect for the male, and that the horn-like antennae, which 
he describes, must have been the provisional feet of the 
young before they had assumed the adult form. Appa- 
rently he had not seen the memoir of Thompson. In other 
respects his paper contains the fullest description, with the 
most copious and most accurate account of the manners 
and habits of this little creature, that has been published, 
and is concluded by a lengthened disquisition as to the 
cause of the red colour which frequently distinguishes 
them, and which tinges the whole water in which they 
occur with the same hue.
