| The chemical composition of salt licks and the diet of the mountain tapir (Tapirus pinchaque) were studied in the upper montane rain forests (2900-3700 m), in the Parque Regional Natural Ucumari and Parque Nacional Natural Los Nevados, Colombia. We collected water samples from the salt licks, 28 feces and voucher specimens of plants with tapir browsing sign. The chemical analysis of the water from salt licks showed higher concentrations of Na, N-NH4 y N-NO3when compared to the water of a nearby stream used as control. The nitrogen of the water at the salt lick is probably being fixed by Nostoc, a Cynobacteria associated with Gunneramanicata and G. magnifolia, two plants located in the upper part of the rocky cliff from where the water drains to the salt... |

| Proporcionamos los primeros registros de plantas (frutos, semillas) consumidas por Heteromys australis en un bosque premontano, norte de la Cordillera Central, Colombia. El 23.26% de los roedores capturados presentaron restos cuantificables en sus abazones. Encontramos restos de Wettinia kalbreyeri, W. fascicularis (Palmae), Pouteria sp. (Sapotaceae), Nectandra lineatifolia (Lauraceae), Chusquea sp. (Poacea) y una especie no identificada de la familia Sapotaceae. Las semillas de palmas representaron 51.51% del peso relativo de los restos, siendo probablemente un recurso disponible durante varios meses del año y uno de los más importantes en la dieta de este roedor. |

| Documentamos el hallazgo de dos individuos de C. centralis en un fragmento de bosque húmedo tropical de los Andes colombianos. Las características craneales del espécimen colectado (MHNUC 0441) concuerdan con las suministradas para C. centralis, excepto en la forma del proceso coronoide de la mandíbula. Los murciélagos estaban perchados a 2 m sobre el suelo, en el envés de una hoja que presentó orificios pequeños utilizados para anclar sus pies. Es posible que Centronycteris modifique el sustrato para adecuar su refugio. El análisis del contenido intestinal sugiere flexibilidad en su comportamiento de forrajeo, buscando insectos posados en la vegetación, y también mediante cacería aérea. |

| Thirty seven species and subspecies of ammonites of the families Ancyloceratidae Gill, 1871, and Heteroceratidae Spath, 1922, are described. The following new taxa are described; Crioceratites (Paracrioceras) leyvaensis, C. (P.) royogomezi, C. (P.) cabreraensis, Pedioceras multicostatum, Pseudocrioceras guanense, Kutatissites creutzbergi, K. densecostatus compactus, K. etayosernai, K. grandis, K.? galanensis, Ammonitoceras galanense, A. giganteum, Hamiticeras ventrotuberculatum, H. longum, Hemihoplites (Matheronites) ridzewskyi sachicaensis, Colchidites riosuarezi, C. pseudovulanensis, C. guanensis and C. striatosulcatus. Moreover, one new genus, Laqueoceras gen. nov., with the type species L. laqueus sp. nov., is proposed. |

| From June till December 1987 an inventory of the excavating sponges of the Santa Marta area, Colombian Caribbean, was made by scuba diving to depths not exceeding 18 m. Sixteen species were recorded and compared morphologically, using spicule sizes, papillae shapes, and excavation characteristics. Four littleknown species are fully described and illustrated by submarine color photographs in situ. One appears to be a new species: Axinyssa flavolivescens, belonging to a genus not known to excavate so far. The other three species could not be identified with certainty: Aka äff. xamaycaensis, Aka aff. brevitubulata, and Cliona aff. flavifodina. A key to the excavating sponges of the area studied is provided. |

| A large amount of unidentified material of the Neotropical genus Guatteria (Annonaceae) is lying on herbarium shelves around the world. Here twelve species are described in an attempt to reduce this amount of unidentified material. Next to this, previously unidentified material is now assigned to G. asplundiana, G. microcarpa, G. pastazae, and G. scalarinervia, four previously described but poorly known species, thus providing a clearer circumscription of these species. Furthermore, G. discolor and G. megalophylla appear to have a wider distribution than previously thought. Lastly, G. macrantha, a curious species only known from the type, is excluded from the genus and referred to Uvaria. With the description of twelve new species and the synonymizing of... |

| On the basis of new and published palaeontological and stratigraphical data, the qualitative and quantitative variations in the Barremian-early Albian ammonite fauna of Colombia have been documented and analyzed. The position adopted here is that in the early Barremian the Andean Province became replaced by the Caribbean Subprovince in Colombia. The Caribbean Subprovince became separated as an independent unit from the Andean Province on the generic level (Buergliceras, Pedioceras), but especially on the species level. In the middle/upper Aptian many new endemic genera and subgenera appeared; Juandurhamiceras, Neodeshayesites, Laqueoceras, Zambranoites, Riedelites and Pseudoptychoceras. Besides, many endemic middle Aptian species of other, non-endemic... |

| Lower Cretaceous plant fossils are described systematically from marine deposits near Villa de Leiva (Boyaca region, Colombia). Specimens originating from the same localities kept at the Florida Museum of Natural History (Gainesville) were included in the systematic description. The plant fossils belong to the Pteridophyta, the Cycadophyta, the Coniferophyta, and to taxa of uncertain affinity which, following previous authors, are referred to the angiosperms. Two new species of Coniferophyta are described, viz. Cupressinocladus hoedemaekeri sp. nov. and Brachyphyllum winklerprinsii sp. nov. Also, Thuites sutamarchensis Huertas is transferred to the genus Cupressinocladus. Fossil plants, Lower Cretaceous, Leiva Region, Colombia. |
