hairs round the lateral and posterior margins ; two or 

 three pairs of shorter, but otherwise similar hairs 

 arising from the ventral surface and extending beyond 

 the hind margin ; and two longitudinal rows each of 

 about four or five similar hairs on the notogaster. 



Oribata avenifera (p. 264), — Since the publication of 

 vol. i of this book Berlese has described and figured 

 in his ' Acari, &c. Ital.,' fasc. xxx, an Oribata which he 

 calls 0. jjunctum ; as far as I can judge from the plate 

 and description, it appears to be identical with 0. 

 avenifeia. 



.The tibise of the second pair of legs in this species 

 have projections like those of the fourth pair. 



S err arms micro cephalus (p. 272). — Long subsequent 

 to my pointing out the exceptional mandibles of this 

 species and the necessity for creating a new genus to 

 receive it and any similar forms, which genus I called 

 " Serrarius," Prof. Berlese, who apparently had over- 

 looked my paper on the subject and the first volume of 

 this book, remarked the same thing, and founded a 

 genus which he called Neozetes upon precisely the same 

 species and characters ('Acari, &c. Ital.,' fasc. xx, 

 March, 1885); he called his species /^isi/er, identifying 

 it, for some reason which is not explained nor altoge- 

 ther apparent, with Koch's Oribates fiisifer (Heft 81, 

 fig. 3), and giving Nicolet's name of microcejphala as a 

 synonym ; he also gave another species of the genus, 

 which he called Neozetes bicomis. In his notes to the 

 same work, fasc. iii, p. 24, published in April, 1885 

 (the notes are separate fasciculi) Prof. Berlese states 

 that Prof. Canestrini and I have described this species 

 as Leisoma microcephala, which, in my own case, is 

 perfectly true as regards my paper in the ' Journal of 

 the Royal Microscopical Society ' in March, 1879, but 

 Prof. Berlese omits to state that in my paper in the 

 same Journal in January, 1883, and again in the first 

 volume of this book, 1 pointed out that it was not a
