1804, or better in 1794, for Hermann's work appeared ten 

 years after his death by the care of his father, Pycnogonids were 

 called miles too , and so it cannot surprise us that Hermann 

 placed these animals into his Holeira without any objection. But 

 he brought the genus Phalanglum into this group with some doubt. 

 He says p. 11 : 



c( J'ai ajouté le genre des faucheurs {phalangium) , qui 7ne paroit 

 offrir le même caractère , en n'y comprenant cependant que la pha- 

 langium opilio et les espèces semblables, à l'exclusion de celles, 

 qui en diffèrent trop. » 



3 The oldest name for the group of Oribates and its congeners 

 is that given by Dugès in 1834 viz: Onôa^^ei ; also used by Gervais 

 Apt III p. 153. Afterwards Koch chose the expression Carabodides in 

 his Uebersicht des Arachnidensystems, 1842. Van der Hoeven created 

 the term Notaspidea in his Handboek der Dierkunde 1849 , p. 669; 

 Nicolet called it Oribatidés {Oribatidae) , 1855, which term was 

 also used by GERSXäCKER in his Handbuch für Zoologie H. p. 342. 

 1863, by Harting in his Grondbeginselen der Dierkunde HI. 

 p. 350 , who cited as synonym Van der Hoeven's Notaspidea, 

 1870; by Donnadieu, 1875, in his Recherches sur les Tétraniques; 

 by Gervais and Van Beneden, 1869, in their Zoologie medicale, 

 1869. H, p. 455. and by Mégnin, 1876, in the Journal d'Ana- 

 tomie et de Physiologie , XH , 293. — Grube called these mites 

 Carabodidae in 1859 (Arch. Nat. Liv. Ehst. Kurl. (2) I, p. 434, 

 461); Anderson Oribatides in 1863 (Oefv. Kong. Vet. Acad. Förh. 

 p. 186); Canestrini and Fanzago Oribatidi in 1877 (Att. R. 

 1st. Ven. Sc. Lett. Art. (5) HI) and Oribatiui in 1877 (Att. R. 

 1st. Ven. Sc. Lett. Art. (5) IV, p. 8). 



4. — - Müller denied by Linné and De Geer? — As I said 

 above, Müller created the genus Hi/drachna already in 1769, 

 and not in 1776, in his Zool. Dan. Prod., as is so often believed 

 and asserted. In the preface of his valuable work , entitled ìììjdrachnae , 

 quas in aquis Daniae palustribus detexii, etc. . . ., Lipsiae,1781 , 

 he tells us, p. V:
