Bibliographical History. — A species of this genus is 
figured by Herbst, in the Berlin c Gesellsch. Skrift./ 1780, 
and described under the name of “ See-laus vom Hemor- 
fisch /’ but the genus was first established by M. Latreille 
(Cuv. Begne An., iv, 1829), to receive the species of 
Caligus described by Muller under the name of Caligus 
productus. It was not remarkably well characterised or 
defined, being taken from the figure merely of that species, 
as given by Muller ; but it has been adopted by succeed- 
ing naturalists to a greater or less extent, and latterly 
more distinctly defined and limited by M. Edwards, in his 
f Hist. Nat. Crust/ Burmeister, in the £ Nov. Act. Acad. 
Nat. Cur./ xvii, objected to the name, and proposed that 
of Dinematura, as being more euphonious and more 
grammatically constructed. Judging, however, from his 
figures and descriptions, it is evident that his genus 
Dinematura is quite different from the Dinemoura of 
Latreille, taking the Caligus productus as the type ; and 
as M. Edwards very properly points out (1. c. iii, 463, 
note), it is synonymous with the genus Nogaus of Leach, 
already well defined by that author several years previously. 
M. Edwards, in adopting this genus, as distinct from 
Pandarus of Leach, points out distinct generic characters, 
and sets it upon a better foundation than had heretofore 
* Prom two ; vr\\ia, a thread ; and ovpa , a tail.
