1. A. persicus (Oken, 1818) Fischer, 1827. — Host: 
Gallus gallus. Localities : Provinces of Havana, Matanzas, 
and Santa Clara. This species has been known in the is- 
land for many years. The country-people call it and its 
larvae “garrapatillas.” As in other countries, it has been 
shown rather frequently in Cuba that this parasite trans- 
mits spirochetosis of poultry. 
G. Ornithodoros Koch, 1844 
2. 0. megnini (Duges, 1883) Neumann, 1896. Host: 
Equus caballus. Locality: Province Havana. It does not 
appear to be common. I have only encountered it once, on 
a native horse, and I cannot assure that it is actually in- 
digenous. If it is shown later not to be indigenous, it 
should be struck out from the list. 
3. 0. marginatus Banks, 1910. Locality: Guanajay 
Mountains, Prov. Pinar del Rio. It is restricted to bats. 
Two larvae, possibly of this species, were taken by Mr. P. 
Bermudez off a bat, Eumops glaucinus (Wagner), at 
Caibarien, Prov. Santa Clara. 
II. Ixodidx Murray, 1877 
G. Dermacentor Koch, 1844 
4. D. nitens Neumann, 1897. — Hosts: Equus caballus, 
Bos taurus, and also Epicrates angulifer Bibron. Localities : 
Provinces of Havana, Pinar del Rio, Santa Clara, Matanzas, 
and Camaguey. This tick was first recorded from Cuba by 
N. S. Mayo (1906). It is widely distributed over the entire 
island. I have found it parasitizing indiscriminately 
equines and bovines, but more particularly the former, in 
the ears, in the region of the anus and perineum. I have 
found it also once on a “Maja de Santa Maria” (Epicrates 
angulifer) captured at Calabazar de Sagua (Prov. Santa 
Clara) . 
G. Rhipicephalus Koch, 1844 
5. R. sanguineus (Latr., 1806) Koch, 1844. — Host: 
Canis familiaris. Localities: Provinces of Havana, Ma-
