ABSTRACT
Entomelas duellmani n. sp. (Rhabditida: Rhabdiasidae) from the lungs and Skrjabinodon cortagoensis n. sp. (Oxyurida: Pharyngodonidae) from the intestines of Mesaspis monticola (Sauria: Anguidae) are described and illustrated. E. duellmani is the sixth species assigned to the genus and is the third species described from the Western Hemisphere. It is easily separated from other neotropical species in the genus by pre-equatorial position of its vulva. Skrjabinodon cartagoensis is the 24th species assigned to the genus and differs from other neotropical species in the genus by female tail morphology.

Seventy-four specimens of Falcaustra lowei n. sp. were recovered from the intestines of 9 of 42 (21%) Tarahumara frogs. Rana tarahumarae, from Sonora, Mexico. F. lowei is the 14th Nearctic species to be described and belongs to that group of species possessing a pseudosucker, namely F. catesbeianae, F. chabaudi, F. chelydrae, F. mexicana, and F. wardi. The new species can be readily differentiated from these by the arrangement of caudal papillae and length of spicules. Priority description of F. affinis is established and F. concinnae is removed from synonymy with F. affinis. In addition to F. lowei, 3 species of Digenea, Glypthelmins quieta, Haematoloechus breviplexus, Langeronia macrocirra; 1 species of Eucestoda, Ophiotaenia magna; 7 species of Nematoda, F. inglisi, Foleyellides striatus, Oswaldocruzia pipiens, Rhabdias ranae, Subulascaris falcaustriformis, Physaloptera sp. (larvae): and 1 species of Acanthocephala, an unidentified oligacanthorhynchid cystacanth, were found.

From Hispaniola, an island in the West Indies, 6 species of anoles, Anolis cristatellus, Anolis etheridgei, Anolis eugenegrahami, Anolis hendersoni, Anolis monticola, and Anolis olssoni were examined for helminths. Helminths representing 2 species of trematodes, Mesocoelium monas and Urotrema scabridum; 1 species of cestode, Oochoristica maccoyi; 11 species of nematodes, Atractis scelopori, Oswaldocruzia lenteixeirai, Parapharyngodon cubensis, Skrjabinoptera leiocephalorum, Trichospirura teixeirai, Ascarops sp., Physocephalus sp., Porrocaecum sp., Rhabdias sp., Acuariidae gen. sp. and Cosmocercidae gen. sp.; and 1 species of acanthocephalan, Centrorhynchus sp., were found. Skrjabinoptera leiocephalorum, Ascarops sp., and Physocephalus sp. from A. cristatellus and all helminths recovered from the other 5 anole species represent new host records.

Four hundred and fifteen Anolis acutus from St. Croix, U.S. Virgin Islands were examined for helminths. Three nematodes, Ascarops sp. (larvae), Parapharyngodon cubensis, and Spauligodon caymanensis, and 2 acanthocephalans, Centrorhynchus sp. and Oligacanthorhynchus sp. (cystacanths), were found. The highest prevalence (47%) and mean intensity (21.3) were recorded for S. caymanensis. Anolis acutus is a new host record for each of these helminth species.

Examination of the stomach contents of 115 Caiman yacare Daudin, 1802, from Paraguay revealed the presence of the nematodes Brevimulticaecum baylisi (Travassos, 1933), Brevimulticaecum stekhoveni (Baylis, 1947), Contracaecum sp. of Railliet and Henry, 1912, Dujardinascaris paulista (Travassos, 1933), Eustrongylides sp. of Jagerskiold, 1909, Micropleura vazi Travassos, 1933, and Ortleppascaris alata (Baylis, 1947). Nematode prevalence was 28%; greatest species prevalence (14%) was found for B. baylisi. Greatest mean intensity, 25.4, was for Contracaecum sp. All occurrences are new host and distribution records.
