 Protiste endoparasite de la Tique, Rhipicephalus sanguineus, du 

 Gondi {Ctenodactylus gundi). [Cryptoplasma rhipicepJiali, gen. et.,

Rhipicephalus sanguineus, Latr., is one of the most common parasites 

 of the gondi, a rodent occurring in south Tunis. This tick is found also 

 on the dog, rabbit and some birds and may be connected with the cases 

 of Toxoplasma among these hosts. It is probably a transmitter of 

 Piroplasma quadrigeminum, NicoUe, with which the gondi is infected 

 to a high degree. Investigations in connection with Toxoplasma led 

 to the discovery of a new parasite, Cnjptoplasma rhipicephali, occurring 

 in the alimentary tract or body cavity of a single nymph. This parasite 

 is described and compared with the Haemogregarine of the gecko, 

 Tarentola mauritunica.

 a Peruvian Disease. — Jl. of Parasitology, Urbana, III, ii, no. 2, 

 December 1915, pp. 67-73, 1 fig. 



The disease known as " Uta," occurring on the west face of the 

 Andes in Peru, has been proved to be due to a Leishmania, and Forci- 

 poimjia utae and F. toivnsendi, native to the western Andean region, 

 appear to be proved capable of transmitting this parasite, which is 

 voided by them from the anus while feeding. Infection must take 

 place when the bites are rubbed. The seasonal prevalence of the 

 disease from November to April, which are the rainy months, coincides 

 with the period of greatest prevalence of the insects. It may prove 

 that these midges, while normally confining their attacks to other 

 insects, have become accustomed, during their periods of greatest 

 abundance, to transfer their attacks to man owing to a shortage of 

 the food-supply. That other insects also transmit Leishmania is 

 very probable. Certain Tabanids probably carry the organism of 

 " apaicha " in the eastern rain-forest region. In the Amazonas 

 province of Peru the natives accuse a new species of Ornithodoros 

 alhed to 0. turicata, Duges, of carrying " uta " by its bites, but this is 

 considered improbable. Fleas, bed-bugs and ticks seem excluded in 

 the case of this disease and other Peruvian leishmaniases, as the 

 lesions are practically confined to the exposed parts of the body.

 scutalum. — Jl. of Parasitology, Urbana, III., ii, no. 2, December 

 1915, pp. 80-86. 



Sheep fed upon insects containing the larvae of Gongylonema scutatum, 

 become infested with this Nematode. Its eggs are present in their 

 faeces and hatch out when swallowed by insects of various species. 

 Gongylonema larvae have been found in various species of dung beetles 

 collected from sheep manure, namely, Aphodiusfemoralis, A. granarius, 

 A. finietarius, A. coloradensis , A. vitfatus, Onihophagus hecate, and 

 0. pennsylv aniens. They have also developed in various species of 

 Aphodius and in the cockroach, Phyllodromia {Ectobia) gernvinica.
