Tlndow seems to have been tiie fu'st to recognize this s])ecies, though its occurreiire upon tlie swan {dytiHus untsuiiis) malccs it rather strange that it sliouhl liave escai)ed observation so long. It is a very small species, as would be interred t'vom the name, and this may account in part for its not luiving been earlier n<»ticed. It has not been recorded from this country, but may be looked for ujjon our species of swans, as the lice infesting these birds are generally widely distrib- uted. LOTISE OF THE (JUINKA I'lG. (dyroiniH iiracU'm Nitzsch.) The guinea pig is ])erhai)s a rather unimportant factor among the domesticated animals, hut it sup- ports its duo (piota of parasites nevertheless, and they require a brief mention, at least. They are quite in- teresting in strn(!tnre, differing largely from any of the species considered hitherto. The one to first receive notice, and probably the one here given, was referred to by Schraidi under the name of roiicitlus porcclli, but Nitzsch, in 1S18, <le- scribed it as (h/ropus gra- cilis, a name which has been used by all subsequent writers. It is referred to generally by writers on the subject, and would seem to be a fairly com- mon species where guinea i)igs are kept. It has not been met with in this country so far as records show, but may l)e looked for with great probability of success in any place where guinea pigs are kept in
