| In this paper a survey is given of the geographic variation and the subspecies of Corvus enca (Horsfield). For that purpose the collections of the Rijksmuseum van Natuurlijke Historie in Leiden and the Zoölogisch Museum in Amsterdam were studied and compared with the literature. My examinations resulted in the following division of subspecies: - Corvus enca compilator Richmond: Malaya, Sumatra, Simalur, Nias, Borneo, (Rhio Archipelago). - Corvus enca enca (Horsfield): Java, Bali, Celebes, Sula Islands, (Mentawei Islands). - Corvus enca violaceus Bonaparte: Ceram (and perhaps Buru). - The birds from Mindoro, Samar, Mindanao, Palawan, Balabac and Luzon possibly belong to two or three subspecies. Geographic variation also appears to exist among the... |

| Individual, sex, age, seasonal and geographic variation of size and plumage coloration of Lesser Whitethroat Sylvia curruca (Linnaeus, 1758) was studied on more than 1100 bird skins from all parts of its breeding range. The results of analysis of birds from the south-eastern part of the breeding range of the species support the validity of five light-coloured subspecies: halimodendri Sushkin, 1904, telengitica Sushkin, 1925, snigirewskii Stachanow, 1929, minula Hume, 1873, and margelanica Stolzmann, 1897. Their diagnoses and ranges are refined and supplemented. Numerous phenotypically intermediate birds from intergradation zones between the subspecies show that these five together with the two northern darkcoloured forms S. c. curruca and S. c. blythi... |

| Notes on the geographic distribution and subspecific taxonomy of Sais rosalia (Cramer) (Lepidoptera, Nymphalidae, Ithomiini), including the first records in Paraguay. This paper provides comments on the subspecific taxonomy and geographic distribution of Sais rosalia (Cramer, 1779) (Lepidoptera, Nymphalidae, Ithomiini), as well as an up-to-date distributional map, complemented with unpublished distributional data based on specimens deposited in the Coleção Entomológica Pe. Jesus S. Moure, Curitiba, Brazil and the Museo de Historia Natural, Lima, Peru. The following synonyms are proposed: Sais rosalia camariensis Haensch, 1905 syn. rev. as junior subjective synonym of Papilio rosalia Cramer, 1779 and Sais rosalia brasiliensis Talbot, 1928 syn. rev. as... |

| The Geoffroy's cat Leopardus geoffroyi (d'Orbigny & Gervais, 1844) is a small cat found in the Southern Cone of South America and, depending on the author, four or five subspecies have been usually recognized (L. g. geoffroyi, L. g. paraguae, L. g. euxanthus, L. g. salinarum and L. g. leucobaptus), mainly based on external morphological characters, such as color pattern of the pelage. In order to clarify the taxonomy of L. geoffroyi, I analyzed approximately 200 specimens housed in museums. I have examined the external and craniodental morphology in quantitative and qualitative terms in the search for patterns of congruent characters that would indicate the existence of taxonomic units. Twenty craniodental measurements were taken and tested by... |

| ABSTRACT The tigrina Leopardus tigrinus (Schreber, 1775) is a small-sized Neotropical spotted cat found from northern Argentina and southern Brazil to Costa Rica. Four subspecies are traditionally recognized: L. t. tigrinus (Schreber, 1775) from northern Brazil, the Guianas and eastern Venezuela; L. t. pardinoides (Gray, 1867) from western Venezuela, Colombia, Ecuador and Peru; L. t. guttulus (Hensel, 1872) from southern Brazil, Paraguay and northern Argentina; and L. t. oncillus (Thomas, 1903) from Costa Rica. We studied external and craniodental morphology in quantitative and qualitative terms from 250 specimens in order to clarify the taxonomic status of tigrina. Based on the characters analyzed in this study, we recognize three diagnosable... |
