into different generic groups. De Blainville informs us, 
that a year or two before that, in 1814, during a journey 
to England, he had been led to see the necessity of sepa- 
rating them into different genera also ; but that he was 
induced to assign them a place amongst the Entomozoa, 
or articulated animals, viewing them, he says, “ as an ano- 
malous group of worms.” He acknowledged, as Oken 
had done, the relations which evidently existed between 
them and the Caligidse, but still did not incline to refer 
them to the Crustacea. This view of these curious animals 
he published in 1816, in his ‘ Prodromus de Classification 
nouv. du RegneAnim.,’ without at the time being aware 
what Oken had previously done. 
In 1817 Cuvier adopted the view taken by Bose, and 
in his ‘ Regne Animal’ placed the Lernese amongst the 
intestinal worms. There is nothing very instructive in 
this detail of the difficulties felt by systematic writers in 
knowing or determining where these curious, and at first 
sight bizarre - looking animals should be placed. Little 
was known of their habits, manners, or mode of propa- 
gation, and though as we have seen, their near relations 
with the Caligi had been observed by several authors, 
they had not sought to resolve the question by deeper 
anatomical researches, or investigations into their mode 
of life and habits. Their true position, however, was soon 
about to be ascertained. Soon after Cuvier had published 
the first edition of his celebrated work, the ‘Regne 
Animal/ a Erench physician at Havre, M. Surriray, made 
the important discovery that the ova were contained in 
the long filaments suspended from the abdomen, and that 
the young, when born, bore no resemblance to their 
parent, but on the contrary were extremely similar to the 
young of the Cyclops. De Blainville recorded the fact 
in the ‘Journal de Physique/ 1822, in his excellent 
article, “ Lernea,” and fully admitted the truth of 
Surriray’ s statement. In this article he remarks the near 
approach of his last genus among the Lerneadse to the 
last of the Caligidae, and traced the almost insensible gra-
