1. The occurrence of Syngamus nasicola Linstow, 1899, in sheep, cattle and goats in the West Indies is recorded.
2. The species is re-described, on the basis of West Indian material and cotypes from deer and goat.
3. The species is contrasted with S. laryngeus Railliet, 1899, with which it has affinities and has hitherto been thought to be identical.
4. Special emphasis is laid on the use of the internal structure of the buccal capsule in differentiating the two species.
5. Syngamus kingi is compared with S. nasicola and it is concluded that the two species are identical, in which case S. kingi becomes a synonym of S. nasicola.
