BRITISH ENTOMOSTRACA. 
Bose, in his * Hist. Nat. cles Crust/ edit. Buffon, par 
Deterville, 1802, gives a very interesting account of this 
genus, as does also Latreille, in his * Hist. Nat. des Crust, 
et Ins./ edit. Button, par Sonnini, 1802 ; but they only 
mention Muller’s species. 
Ramdohr in 1805 published his little work on the 
Monoculi, * in which he gives some very excellent details 
concerning the anatomy of the Cypris, accompanied by 
some very good figures ; but his work does not seem to 
be known to almost any of the succeeding naturalists 
who have written upon the Cypris. He only describes 
in this work the Cypris strigata of Muller; but in 1808, 
in a paper in the ‘ Magaz. Gesell. Nat. Berlin/ he de- 
scribes at considerable length three additional species 
which had not been noticed before. 
M. Daudebart de Ferussac fils, in a memoir in the 
‘ Ann. du Mus. d’Hist. Nat./ vii, 1806, describes one new 
species, and Risso, in his ‘ Hist. Nat. des Crust, des Env. 
de Nice/ 1816, two others; but though these additions 
were made to the number of known species, and although 
Latreille, in Cuvier’s c Regne Animal,’ 1817, and Lamarck, 
in his ‘Hist. Nat. des Anim. sans Vert.,’ 1818, give a 
variety of details relating to the genus generally, little real 
knowledge concerning the anatomy of the inhabitants of 
the tiny shells was conveyed to us (for Ramdohr’s work 
and paper seem to have attracted scarcely any notice), 
till M. Straus published his admirable paper on the 
genus Cypris, in the seventh volume of the ‘ Mem. du 
Mus. d’Hist. Nat.,’ 1821 ; containing a most elaborate 
, anatomical description of the genus, with a notice, and 
figures of three new species, not described by Muller. 
About the same period as Straus read his paper before 
the Academy, appeared Jurine’s splendid work on the 
Monoculi, replete with interesting details of the genus 
generally, and with beautiful figures of eighteen species. 
But we find no reference made by either of these authors 
to the previous labours of Ramdohr.
