A revision of the African genus Myonycteris Matschie, 1899 (Mammalia, Megachiroptera) Naturalis
Bergmans, W..
The fruit bat genus Myonycteris Matschie, 1899, is considered to contain only two valid taxa: the species M. torquata (Dobson, 1878) inhabiting the forest blocks in West Africa and Central Africa, and M. brachycephala (Bocage, 1889) from the island of São Tomé. M. wroughtoni Andersen, 1908, and M. leptodon Andersen, 1908, are considered synonyms of M. torquata. The subgenus Phygetis Andersen, 1912, proposed for the species brachycephala only, is sunk into the synonymy of Myonycteris. A number of new (collecting) localities for torquata is recorded, among which the first one in Nigeria. Data are included on morphological variability, sexual dimorphism, ecology and biology. The possible type locality of torquata, and some evolutionary trends within the genus...

A revision of the genus Mastixia (Cornaceae) Naturalis
Matthew, K.M..
A revision of the genus in its entire range of distribution is presented. Out of more than 50 published specific names, 9 species (with 13 subspecies or varieties) are recognized, in addition to 4 new species and one new subspecies. The two subgenera Pentamastixia and Tetramastixia of Wangerin (1910) are shown to be artificial. Two new subgenera, Manglesia Matthew (2 species) and Mastixia (II species) are established. The former is separated on the basis, among others, of stamens (8), calyx (subtruncate), inflorescence branches (4- angular), and fruits (with swollen septum). The last character is expected to be of value in identifying fossil fruits. This subgenus has a disjunct distribution, broken up into two small areas, one continental, the other W....

A short review of the Surinam Loricariinae; with additional information on Surinam Harttiinae, including the description of a new species (Loricariidae, Siluriformes) Naturalis
Boeseman, M..
INTRODUCTION The present paper forms the continuation of a series pretending to cover at least most of the Surinam representatives of loricariid armoured catfishes (for earlier papers, see Boeseman, 1968, 1969, 1971, and 1974), but for various reasons it is less extensive in scope than its forerunners. The main reasons are that, (1) it seems unnecessary to repeat the general information provided in the earlier papers, especially since the employed methods, the provided measurements (see fig. 1), and the localities (fig. 2) or habitats are the same, or at least similar (exceptions: measurements and counts up to "caudal base" in fact are up to the end of the last, small scute of the lateral series, while in some of tables, to the total (or axial) length, the...

A SIMPLE ANALYSIS OF ACREAGE RESPONSE TO SOME AGRICULTURAL PROGRAMS AgEcon
Danin, Yigal.
The purpose of this paper is twofold: (a) To analyze the effect of some common agricultural programs on the planted area of a crop. This will be done with the framework of a simple model mostly by graphical methods. (b) To comment on an estimative procedure by which a support price, which is linked to acreage restrictions, is transformed to an "effective support price." Three programs will be analyzed, namely, unlinked support price, link support price and diversion payment.

A statistical relationship between individual heights and periods of storm waves ArchiMer
Cavanie, Alain; Arhan, X; Ezraty, X.
The goal of this short communication is to present a theoretical joint probability distribution for wave heights and periods developped in 1975 at the Centre 0céanologique de Bretagne. This research program was proposed and financially supported by the Association de Recherche Action des Elements (group fomed of 9 french companies or government agencies) which also carried out analysis of 200 twenty minute storm wave recordings in the North Sea selected from Waverider data kindly placed at our diaposal by the United Kingdom Offshore Operators Association.

A synopsis of the Malesian species of Osmoxylon (including Boerlagiodendron), Araliaceae Naturalis
Philipson, W.R..
A synopsis is given of the genus Osmoxylon, Araliaceae, in Malesia and the Bismarck Archipelago, including also one species of the Solomon Islands. In the introduction arguments are given why the genus Boerlagiodendron is merged with Osmoxylon. In all 41 species are recognized and are keyed out. Of each species the synonymy is given, as well as the distribution and collections examined; sometimes critical notes on affinity and variability are added. Two names of which the types are apparently lost and which could not be satisfactorily placed are added as insufficiently known. Nine new species have been described and 20 new combinations appeared to be necessary. Full descriptions of all species will appear in the Flora Malesiana treatment of Araliaceae to...
