to the same extent as the millimetre-scale, where the ultimate 
divisions are tenths. In this way I have been able to get 
accurate measurements of the various parts of the body, from 
which some interesting comparative results were obtained. 
Further investigation showed this Copepod to be an entirely 
ew form; and this opinion was confirmed by Dr. Brady, to 
whom some specimens were submitted. I propose to name it 
Gotdelia japonica. 
After carefully examining many individuals, and comparing 
them with descriptions of parasitic and semi-parasitic Copepods, 
I find they most resemble the Herstlizde, as described by Claus *, 
Canu 7, and Kossmann {. The affinities of this family are still 
uncertain, and, though Gozdelia japonica is apparently related 
to this group, yet itis more truly endo-parasitic than either of the 
three known genera which have so far made up the family. But 
apart from the difficulty arising out of the unsettled condition of 
the affinities of this family, I find that its name, Herszlide, is 
already occupied by a well-known family of Spiders, possessing 
also the genus Hersilia; there is, moreover, a genus Hersilia in 
the Coleoptera and also in the Diptera. On looking up the 
literature on these four different groups, it is clear the name 
belongs—by right of priority—to the Arachnida: as the spider 
Hersilia (Audouin) appears in 1825-27 in Savigny’s ‘ Description 
de ’Egypte.’§ The next to receive the name was the beetle of the 
family Chrysomeline, which was christened in 1834 by Dejean || , 
It was not until November 2nd, 1839, that Dr. A Philippi 4 
found the Crustacean, which he called Hersilia apodiformis, 
describing it as “Ein neues Genus der Entomostraceen.”’
