Abstract:Notre connaissance des chauves-souris habitant la partie cotiere occidentale de la Haute-Guinee est encore tres incomplete. Les prospections ont cependant dejä conduit a de nombreux resultats surprenants. Ce district est en effet remarquable au point de vue , biogeographique et faunistique, en ce qu'il forme une "zone de passage entre la zone cotiere couverte de foret primaire a Test et les savanes du nord et du nord-ouest et que les elements faunistiques correspondants s'y melangent. De nombreux elements prop… Show more
“…It is interesting to note that although L. angolensis and R. aegyptiacus have been found in Guinea sharing the same cave (Eisentraut and Knorr, 1957), they have different bat flies. This probably results from the bats using different parts of the cave, jR. aegyptiacus being able to venture into darker parts because of its ability to echoiocate.…”

“…Nous avons collecte 49 specimens de cette espece consideree com me peu commune par Rosevear (1965); sur cette serie nous avons pu constater l'homogeneito de la forme du tragus ( fig. 1) Monard (1939) decrit N. aethiopica guineensis forme aurantiaca sur un spocimen de Guinee Bissau; Eisentraut et Knorr (1957) notent que des exemplaires de Guinoe sont nettement brun-rouge tre; Fain (1953) observe toutes les gradations de couleur entre brun-gris et orange vif sur une sorie originaire du Ruanda-Urundi. II est done clair que ces variations de couleur ne sont lioes ni la taxinomie, ni une variation geographique, mais peuvent etre soit de simples differences individuelles, soit des modifications liees la reproduction ou Tage des sujets.…”
“…Hipposideros jonesi: The single female is rather large in comparison to specimens from western Guinea published by Eisentraut and Knorr (1957;4;;, 3 and ascribed this to a morphological cline, with populations from the west (Sierra Leone) being significantly smaller than populations from the east (Ghana). However, specimens from even further east (central Nigeria) are smaller than those from Ghana and populations from Mali, Burkina Faso and Côte d'Ivoire show considerable variation as well (J.…”
