As to the specific name Giebel says, " With regard to the 

 name, Denny has adopted the Linnean name, while Bur- 

 meister has transformed Nitzsch's Greek name {oxyrhynchm) 

 into Latin. As it is certainly inadmissible to name^ this 

 parasite after its host, Burmeister's denomination, as published 

 before Nitzsch's, must be regarded as having the first right. 

 Burmeister was certainly, in the wrong to convert Nitzsch s 

 Greek name into the Latin one, as he ought to have preserved 

 the right of priority for Nitzsch ; on the other hand, however, 

 he published his name first, and this name has since taken 

 its place in literature, so that it does not seem advisable to 

 change it again. 



The Sharp-headed Ox-louse lives on the neck and head of 

 cattle. It is very sluggish, and moves but rarely from its 

 place ; it usually remains quite quiet, with its proboscis buried 

 in the skin, so that it requires some effort to remove it from 

 the ox. Its eggs it deposits near the base of the hairs of its 

 host. They are always attached so that the micropylar appa- 

 ratus is turned towards the tip of the hair. Moreover there 

 is generally only one nit upon a hair, rarely two, and these 

 attached at some distance from each other. Only once I found 

 three upon one hair, placed immediately over one another, 

 and in different stages of development. It is principally upon 

 badly nourished and young animals that these lice are para- 

 sitic. I must not pass without notice the fact that, as in the 

 case of very many lice of the family Pediculidse, the number 

 of females is considerably in excess of that of the males. 

 Thus among about one hundred females I found only seven

The best means of keeping away these visitors, which are 

 so unwelcome to the farmer, are undoubtedly cleanliness, 

 careful currying, and good feeding. But if the parasites 

 make their appearance they may be got rid of, according to 

 Taschenberg (14, p. 102), by combing the infested animals 

 with a close-toothed comb, by washing with a mixture of 

 soap, benzine, and water, or with a decoction of semen staphy- 

 sagrice, or tobacco in water, by rubbing in Persian insect- 

 powder or grey mercurial ointment, and other remedies. 

 Quite recently Falkenberg's chemical factory at Griinai 

 Berlin, has advertised " Parasite neck-rings," by wearing 

 which " any animal may with certainty and without danger 

 be freed from parasites (lice, fleas, &c.) within twenty-four 

 hours, and preserved in a clean state." Nevertheless I cannot 

 help having some little doubt as to the efficacy of this last- 

 named remedy.
