Lermeopodidee; Chondracanthida seem to me to differ much more, and Ascomyzontidxe do 
not show any real relationship. 
The authors quote and criticise at great length all that has been written about this 
family, but in their eagerness to exhaust the matter, they seem to go a little too far. They 
give a long quotation from H. Kréyer: »Monografisk Fremstilling af Slegten Hippolyte’s 
nordiske Arter (Kg). Danske Vidensk. Selsk. Skrifter, Nat. Math. Afh. IX, 1842, p. 263—64) 
in order to prove that this excellent investigator was the first to discover an animal of this 
family, and. that his specimen belonged to the genus Choniostoma. ‘They quote the passage 
in Danish (p. 368—69) and in a French translation; the latter is correct, except in three 
points, of which one may be called a very free translation, whereas the others are indeed 
important mistakes and will be mentioned presently. “Kroyer states that he has found a 
specimen of Hippolyte gibba (from Spitzbergen), whose carapace was much swollen on both 
sides; however, he found no Bopyrid in it, but about a score of sub-globular, yellowish white 
bodies of different size (from °/5‘’ to nearly 11/2‘’ in diameter), which were lying free and 
unconnected side by side. He supposes them to be eges of an unknown parasite and adds: 
»the smaller ones I found filled with a yolk-like, granulous substance« {»de mindre af dem 
har jeg fundet opfyldte af en eggeblommeagtig, grynet Masse«|, which Giard and Bonnier 
translate as follows: »Les plus petits étaient remplis d'une masse grenue ressemblant a des 
oeufs«, but this gives a very different meaning from the word »yolk-like«, and may quite 
well be understood, as if the globules were ovisacs containing the eggs of a Choniostoma, 
though Kréyer’s expression does not imply such an idea at all. Kréyer continues: »In the 
larger globules, which were probably very near maturity, I have noticed a rather long 
(6—7'), thin, vermiform body. It may be, that some leech-like animal develops itself out 
of these eggs« [»i de storste, som rimeligviis vare nerved Modenhed, har jeg iagttaget et 
temmelig langt (6—7‘“) tyndt, ormedannet Legeme. Maaske udvikler der sig altsaa af 
disse Aig et igleagtigt Dyr«|. Judging from the two sizes indicated by Kroyer, we might 
suppose that the larger globules were females, the smaller ones ovisacs of a Choniostoma, 
but it seems to me very improbable, that a naturalist like Kroyer should not have seen 
that the small globules in reality contained eggs or larve, instead of supposing their 
contents to be a yolk-like, granulous substance, and his statement that he found a vermiftorm 
body about 13—15 millim. in length in the large globules, must in my opinion do away with 
any idea that it could be the female of a Choniostoma (comp. my description of this genus 
later on). But then, how shall we explain that Giard and Bonnier could advance such an 
opinion? Well, in their translation of Kréyer’s description of the contents of the large 
globules, they translate the first words: »7 de storste« |»/m the larger ones«| by: »prés des 
plus gros« which gives quite a different meaning, allowing this remarkable, vermiform body 

to be taken for a free animal belonging to another class. Thus two faults in their trans- 
lation of Kroyer lead them to find a similarity which does not really exist between a Cho- 
niostoma with its ovisacs and Kréyer’s description. IT am unable to tell what the objects
