The Rhipicephalus capensis Koch, noted by me in the 

 journal, same page, were recognised by Prof. Neumann as a new 

 species: Rhipicephalus evertsi Nn., described by him in the Me- 

 moires de la Société Zoologique de France, 1897, p. 405 — 407. 

 I have only to rectify the passage that these animals were caught 

 by Dr. Everts. In 1890 Dr. Everts, of the Hague, received them 

 only from Transvaal.

Fabricius already found in 1779 an Acarus in Fucus which 

 he described as follows : 



» Acarus fucorum pallidus ; lineis duabus flexuosis nigris, pedihus 

 posticis brevissimis incurvis. Corpus parvum, pediculo minus, totum 

 pallidum, lineis duabus dorsalis flexuosis nigris. Pedes octo breves, 

 unguiculati, postici brevissimi, incurvi'\ 



I ara convinced of it, that his Acarus fucorum is the same 

 animal as my mite of Cherbourg (vide supra, p. 278). The mite 

 is pale, and has two curved black lines, when seen on its back. 

 (These lines are two tracts of the intestine, filled with opake
