1. A. per stem (Oken, 1818) Fischer, 1827— Host: 
Gallus g alius. 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.

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: Guana jay 
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.

4. D. nitens Neumann, 1897.- — -Hosts : Equm 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) .
